id=\"3-eael-table-of-content\" class=\"wp-block-heading\">Properties<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Tool steel H11 possesses an exceptional combination of attainable hardness, red hardness (hot hardness), toughness, and wear resistance.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Strength: It can be heat-treated to yield strengths of 0.2% well above&nbsp;1380 MPa (200 ksi)&nbsp;and ultimate tensile strengths exceeding&nbsp;2070 MPa (300 ksi).&nbsp;<\/li>\n\n\n\n<li>Hardness: Normal working hardnesses typically range from 40 to 55 HRC. For applications such as aluminum die casting, a preferred hardness of 47 HRC is noted. In die casting, H11 dies can be hardened to 42\u201352 HRC; inserts and cores to 46\u201352 HRC; plungers to 46\u201350 HRC; slides to 46\u201352 HRC; shot sleeves to 44\u201348 HRC; and nozzles to 32\u201342 HRC. For hot forging punches and dies, hardness typically ranges from 44\u201348 HRC. Hot-rolling mill rolls (for short runs and low temperatures) are made of H11 at 40\u201348 HRC. Hot swaging dies are typically 48\u201352 HRC.<\/li>\n\n\n\n<li>Hot Hardness\/Red Hardness:&nbsp;Good temper resistance, maintaining high hardness and strength at elevated temperatures. It resists softening during continuous exposure to temperatures up to 540 \u00b0C (1000 \u00b0F). While its hot hardness is lower than some other hot-work steels, such as H19 or H21, it still retains hardness better than other medium-alloy steels at higher temperatures. Hot Hardness\/Red Hardness is a very important property for hot-work tool steels.<\/li>\n\n\n\n<li>Toughness and Ductility:&nbsp;Good ductility and impact strength. It has better resistance to brittle fracture than higher-alloy-content steels such as H14, H19, and H21. Electroslag remelting (ESR) or vacuum arc remelting (VAR) processes can significantly improve ductility and toughness.<\/li>\n\n\n\n<li>Fatigue Resistance: This material offers high fatigue resistance and thermal stability over a temperature range of 75 to 540\u00b0C (167 to 1000\u00b0F). Compared with 4340 steel that has undergone the same high-intensity heat treatment, H11 has better fatigue strength.<\/li>\n\n\n\n<li>Wear Resistance: Its wear resistance is lower than H13&#8217;s.<\/li>\n\n\n\n<li>Weldability:&nbsp;It&nbsp;is readily weldable, even in heavy sections.&nbsp;<\/li>\n\n\n\n<li>Machinability:&nbsp;Good machinability, rated around 70% of a standard 1% carbon steel.<\/li>\n\n\n\n<li>Thermal properties: It has a relatively low coefficient of thermal expansion and a thermal conductivity of 26 W\/m\u00b7K.<\/li>\n\n\n\n<li>Corrosion Resistance: Above-average resistance to oxidation and corrosion.<\/li>\n\n\n\n<li>Heat Checking Resistance: Good resistance to thermal fatigue (heat checking).<\/li>\n<\/ul>\n\n\n\n<h2 id=\"4-eael-table-of-content\" class=\"wp-block-heading\">H11 Tool Steel Heat Treatment<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Precise&nbsp;<em>heat treatment<\/em>&nbsp;of H11 tool steel is crucial to achieving optimal performance as a 5% chromium hot-work die steel and an&nbsp;ultrahigh-strength steel, similar to H11 Modified and H13. This process tunes the microstructure for demanding factory tooling.&nbsp;<\/p>\n\n\n\n<h3 id=\"5-eael-table-of-content\" class=\"wp-block-heading\">Forging<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">This steel is easily forged, with a suitable forging temperature range of&nbsp;1120 to 1150\u00b0C (2050 to 2100\u00b0F). We recommend&nbsp;preheating the billet to 790-815\u00b0C (1450-1500\u00b0F), then uniformly heating it to the forging temperature. The forging temperature must&nbsp;NOT&nbsp;be lower than&nbsp;925\u00b0C (1700\u00b0F). If the temperature drops near this level, it must be reheated before continuing the forging process.<\/p>\n\n\n\n<h3 id=\"6-eael-table-of-content\" class=\"wp-block-heading\">Austenitizaci\u00f3n<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Austenitizing, the primary hardening step, involves heating to transform its structure into austenite. This allows uniform conversion and dissolution of alloying elements and carbides.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Preheating:&nbsp;Preheat H11 to 760-815 \u00b0C (1400-1500 \u00b0F) before austenitizing to minimize thermal shock and cracking, especially for this high-alloy material.<\/li>\n\n\n\n<li>Austenitizing Temperatures and Soaking Times:&nbsp;The Austenitizing Temperature is 995-1025 \u00b0C (1825-1875 \u00b0F). The soaking time is 20 minutes + 5 minutes per 25 mm (1 inch) of thickness.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Holding at the austenitizing temperature ensures uniform transformation and dissolution.<\/p>\n\n\n\n<h3 id=\"7-eael-table-of-content\" class=\"wp-block-heading\">Temple<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">After austenitizing, H11 steel is rapidly quenched to form hard martensite. H11 is an air-hardening steel that provides uniform hardening throughout large sections with minimal residual stresses and dimensional changes. Air cooling is the standard and preferred method for H11 tool steel. While air cooling is standard, oil quenching from 995 \u00b0C (1825 \u00b0F) is a possible alternative. H11 and other hot-work tool steels must&nbsp;never be water-quenched, as this can lead to cracking.<\/p>\n\n\n\n<h3 id=\"8-eael-table-of-content\" class=\"wp-block-heading\">Templado<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">After hardening,&nbsp;tempering&nbsp;H11 tool steel by reheating to a lower temperature is crucial for improving toughness, relieving stress, and stabilizing properties. Steel H11 is a secondary hardening steel. It achieves its best performance when tempered at temperatures above 510\u00b0C (950\u00b0F). We recommend performing multiple tempering treatments on it to achieve optimal toughness and extend tool life. Allow the parts to cool to room temperature between tempering cycles to minimize residual austenite.&nbsp;<\/p>\n\n\n\n<p class=\"has-text-align-center wp-block-paragraph\"><strong>Table of Hardness and Tempering Temperature for H11 Steel<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td class=\"has-text-align-center\" data-align=\"center\"><strong>Temperatura de templado<\/strong><\/td><td class=\"has-text-align-center\" data-align=\"center\"><strong>Rockwell C<\/strong><\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">As quenched<\/td><td class=\"has-text-align-center\" data-align=\"center\">56<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">700\u00b0F\/370\u00b0C<\/td><td class=\"has-text-align-center\" data-align=\"center\">54<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">800\u00b0F\/425\u00b0C<\/td><td class=\"has-text-align-center\" data-align=\"center\">55<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">900\u00b0F\/480\u00b0C<\/td><td class=\"has-text-align-center\" data-align=\"center\">57<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">1000\u00b0F\/540\u00b0C<\/td><td class=\"has-text-align-center\" data-align=\"center\">56<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">1100\u00b0F\/595\u00b0C<\/td><td class=\"has-text-align-center\" data-align=\"center\">46<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">1200\u00b0F\/650\u00b0C<\/td><td class=\"has-text-align-center\" data-align=\"center\">36<\/td><\/tr><\/tbody><\/table><figcaption class=\"wp-element-caption\">Experimental Conditions: 1.

The cooling rate is&nbsp;22-40\u00b0C\/h (40-75\u00b0F\/h). The hardness after annealing is&nbsp;192-229 HB.<\/p>\n\n\n\n<h3 id=\"10-eael-table-of-content\" class=\"wp-block-heading\">Other Important H11 Heat Treatment Considerations<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Normalizing:&nbsp;This process is generally&nbsp;not recommended&nbsp;for H11 or H13 tool steels due to the high risk of cracking, particularly when surface decarburization occurs.<\/li>\n\n\n\n<li>Stress-Relief:&nbsp;After H11 has been processed, such as grinding, welding, or EDM (electrical discharge machining), we strongly recommend stress-relief treatment at 650\u00b0C. This treatment should be carried out at a temperature 14\u201328\u00b0C (25\u201350\u00b0F) lower than the previous tempering temperature. After stress relief, cool slowly at a maximum rate of 300\u00b0C\/h to prevent the formation of new stresses.<\/li>\n\n\n\n<li>Cryogenic Treatment:&nbsp;Sub-zero treatment (e.g., -73\u00b0C \/ -100\u00b0F) can reduce retained austenite; however, H11\u2019s high tempering temperatures usually make it unnecessary to achieve maximum secondary hardening.<\/li>\n\n\n\n<li>Surface Protection:&nbsp;Protecting its surfaces from oxidation and decarburization during high-temperature treatments, such as austenitizing and annealing, is vital. This is often achieved using controlled atmospheres, vacuum furnaces, or salt baths.<\/li>\n<\/ul>\n\n\n\n<h2 id=\"1-eael-table-of-content\" class=\"wp-block-heading\">Aplicaciones<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Die Casting Dies<\/li>\n\n\n\n<li>Forging Dies<\/li>\n\n\n\n<li>Extrusion Tools<\/li>\n\n\n\n<li>Hot Shear Blades:<\/li>\n\n\n\n<li>Aerospace Components<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"500\" height=\"500\" data-id=\"6292\" src=\"https:\/\/aobosteel.com\/wp-content\/uploads\/2025\/04\/H11-TOOL-STEEL-FLAT.avif\" alt=\"H11 Tool Steel\" class=\"wp-image-6292\" srcset=\"https:\/\/aobosteel.com\/wp-content\/uploads\/2025\/04\/H11-TOOL-STEEL-FLAT.avif 500w, https:\/\/aobosteel.com\/wp-content\/uploads\/2025\/04\/H11-TOOL-STEEL-FLAT-300x300.avif 300w, https:\/\/aobosteel.com\/wp-content\/uploads\/2025\/04\/H11-TOOL-STEEL-FLAT-150x150.avif 150w, https:\/\/aobosteel.com\/wp-content\/uploads\/2025\/04\/H11-TOOL-STEEL-FLAT-12x12.avif 12w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><figcaption class=\"wp-element-caption\">H11 tool steel<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"887\" height=\"887\" data-id=\"10004\" src=\"https:\/\/aobosteel.com\/wp-content\/uploads\/2025\/08\/1.2343-steel.avif\" alt=\"1.2343 steel\" class=\"wp-image-10004\" srcset=\"https:\/\/aobosteel.com\/wp-content\/uploads\/2025\/08\/1.2343-steel.avif 887w, https:\/\/aobosteel.com\/wp-content\/uploads\/2025\/08\/1.2343-steel-300x300.avif 300w, https:\/\/aobosteel.com\/wp-content\/uploads\/2025\/08\/1.2343-steel-150x150.avif 150w, https:\/\/aobosteel.com\/wp-content\/uploads\/2025\/08\/1.2343-steel-768x768.avif 768w, https:\/\/aobosteel.com\/wp-content\/uploads\/2025\/08\/1.2343-steel-12x12.avif 12w\" sizes=\"auto, (max-width: 887px) 100vw, 887px\" \/><figcaption class=\"wp-element-caption\">1.2343 tool steel<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"600\" data-id=\"8787\" src=\"https:\/\/aobosteel.com\/wp-content\/uploads\/2025\/06\/1.2343.webp\" alt=\"1.2343 tool steel\" class=\"wp-image-8787\" srcset=\"https:\/\/aobosteel.com\/wp-content\/uploads\/2025\/06\/1.2343.webp 600w, https:\/\/aobosteel.com\/wp-content\/uploads\/2025\/06\/1.2343-300x300.webp 300w, https:\/\/aobosteel.com\/wp-content\/uploads\/2025\/06\/1.2343-150x150.webp 150w, https:\/\/aobosteel.com\/wp-content\/uploads\/2025\/06\/1.2343-12x12.webp 12w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><figcaption class=\"wp-element-caption\">1.2343 tool steel<\/figcaption><\/figure>\n<\/figure>\n\n\n\n<div class=\"wp-block-group has-ast-global-color-8-background-color has-background is-layout-constrained wp-block-group-is-layout-constrained\">\n<div class=\"wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button has-custom-width wp-block-button__width-100 popmake-16052\"><a class=\"wp-block-button__link wp-element-button\">Formulario de solicitud de cotizaci\u00f3n abierta<\/a><\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n<script type=\"application\/ld+json\">{\n    \"@context\": \"https:\\\/\\\/schema.org\\\/\",\n    \"@type\": \"Product\",\n    \"name\": \"Forged H11 \\\/ 1.2343 \\\/ SKD6 Hot Work Tool Steel Round Bar\",\n    \"image\": \"https:\\\/\\\/aobosteel.com\\\/wp-content\\\/uploads\\\/2025\\\/04\\\/H11-TOOL-STEEL-FLAT.avif\",\n    \"description\": \"High-quality Forged H11 (1.2343 \\\/ SKD6) Hot Work Tool Steel directly from Aobo Steel factory.
