L6 Tool Steel Properties<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">L6 tool steel is categorized as a low-alloy special-purpose tool steel, belonging to the \u201cL\u201d series in the American Iron and Steel Institute (AISI) classification system. Its specific UNS (Unified Numbering System) designation is T61206.&nbsp;<\/p>\n\n\n\n<h3 id=\"4-eael-table-of-content\" class=\"wp-block-heading\">3.1 Mechanical Properties<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Hardness<\/strong><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">It has a flexible range of hardness depending on its condition and treatment:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The hardness range in the annealed state is 183-212 HB, with good machinability. After heat treatment (working hardness), the hardness is&nbsp;45-62 HRC, and after quenching, it can reach a hardness of approximately&nbsp;64 HRC. The hardness <span style=\"box-sizing: border-box; margin: 0px; padding: 0px;\">required for woodworking saws is&nbsp;45-50 HRC, while the hardness of general-purpose tools after low-temperature tempering ranges&nbsp;from 58 to&nbsp;<\/span>62 HRC.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Tenacidad<\/strong><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">L6 material has better toughness compared to many high-carbon oil-hardening grades. This high toughness makes it an excellent choice for tools and components subjected to shock or impact loading. While tensile ductility might be lower at lower tempering temperatures, it significantly improves when tempered above 315\u00b0C (600\u00b0F). L6 also has excellent torsional ductility after appropriate&nbsp;heat treatment.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Wear&nbsp;Resistance<\/strong><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The wear resistance is moderate, lower than that of other tool steels, such as&nbsp;<em><a href=\"https:\/\/aobosteel.com\/es\/o1-tool-steel\/\"><mark style=\"background-color:rgba(0, 0, 0, 0);color:#0693e3\" class=\"has-inline-color\">O1<\/mark><\/a><\/em>&nbsp;or W1.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Hot Hardness and Resistance to Softening:<\/strong><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">L6 tool steel has low hot hardness and low resistance to softening when tempered. Consequently, it is generally not recommended for applications involving service at elevated temperatures. For high-heat environments, dedicated hot-work steels would be more suitable.<\/p>\n\n\n\n<h3 id=\"5-eael-table-of-content\" class=\"wp-block-heading\">3.2 Machinability&nbsp;<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The machinability is medium. The presence of nickel, while beneficial for toughness, makes it slightly less machinable than comparable grades without nickel, such as L2 tool steel.<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-7387b849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"1024\" src=\"https:\/\/aobosteel.com\/wp-content\/uploads\/2025\/07\/L6-1024x1024.avif\" alt=\"L6 tool steel\" class=\"wp-image-9197\" srcset=\"https:\/\/aobosteel.com\/wp-content\/uploads\/2025\/07\/L6-1024x1024.avif 1024w, https:\/\/aobosteel.com\/wp-content\/uploads\/2025\/07\/L6-300x300.avif 300w, https:\/\/aobosteel.com\/wp-content\/uploads\/2025\/07\/L6-150x150.avif 150w, https:\/\/aobosteel.com\/wp-content\/uploads\/2025\/07\/L6-768x768.avif 768w, https:\/\/aobosteel.com\/wp-content\/uploads\/2025\/07\/L6-12x12.avif 12w, https:\/\/aobosteel.com\/wp-content\/uploads\/2025\/07\/L6.avif 1080w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">L6 tool steel<\/figcaption><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><strong>Interested in L6 tool steel?<\/strong> <strong>Please fill out the form below to contact us now!<\/strong><\/p>\n\n\n\n<div class=\"wp-block-contact-form-7-contact-form-selector\">\n<div class=\"wpcf7 no-js\" id=\"wpcf7-f16042-o1\" lang=\"en-US\" dir=\"ltr\" data-wpcf7-id=\"16042\">\n<div class=\"screen-reader-response\"><p role=\"status\" aria-live=\"polite\" aria-atomic=\"true\"><\/p> <ul><\/ul><\/div>\n<form action=\"\/es\/wp-json\/wp\/v2\/pages\/9357#wpcf7-f16042-o1\" method=\"post\" class=\"wpcf7-form init\" aria-label=\"Formulario de contacto\" novalidate=\"novalidate\" data-status=\"init\" data-trp-original-action=\"\/es\/wp-json\/wp\/v2\/pages\/9357#wpcf7-f16042-o1\">\n<fieldset class=\"hidden-fields-container\"><input type=\"hidden\" name=\"_wpcf7\" value=\"16042\" \/><input type=\"hidden\" name=\"_wpcf7_version\" value=\"6.1.6\" \/><input type=\"hidden\" name=\"_wpcf7_locale\" value=\"en_US\" \/><input type=\"hidden\" name=\"_wpcf7_unit_tag\" value=\"wpcf7-f16042-o1\" \/><input type=\"hidden\" name=\"_wpcf7_container_post\" value=\"0\" \/><input type=\"hidden\" name=\"_wpcf7_posted_data_hash\" value=\"\" \/>\n<\/fieldset>\n<p><span class=\"wpcf7-form-control-wrap\" data-name=\"your-name\"><input size=\"40\" maxlength=\"400\" class=\"wpcf7-form-control wpcf7-text wpcf7-validates-as-required\" autocomplete=\"name\" aria-required=\"true\" aria-invalid=\"false\" placeholder=\"Su nombre *\" value=\"\" type=\"text\" name=\"your-name\" \/><\/span>\n<\/p>\n<p><span class=\"wpcf7-form-control-wrap\" data-name=\"your-email\"><input size=\"40\" maxlength=\"400\" class=\"wpcf7-form-control wpcf7-email wpcf7-validates-as-required wpcf7-text wpcf7-validates-as-email\" autocomplete=\"email\" aria-required=\"true\" aria-invalid=\"false\" placeholder=\"Correo electr\u00f3nico *\" value=\"\" type=\"email\" name=\"your-email\" \/><\/span>\n<\/p>\n<p><span class=\"wpcf7-form-control-wrap\" data-name=\"your-message\"><textarea cols=\"40\" rows=\"4\" maxlength=\"2000\" class=\"wpcf7-form-control wpcf7-textarea wpcf7-validates-as-required\" aria-required=\"true\" aria-invalid=\"false\" placeholder=\"Mensaje *\" name=\"your-message\"><\/textarea><\/span>\n<\/p>\n<p><input class=\"wpcf7-form-control wpcf7-submit has-spinner\" type=\"submit\" value=\"Enviar consulta\" \/>\n<\/p><p style=\"display: none !important;\" class=\"akismet-fields-container\" data-prefix=\"_wpcf7_ak_\"><label>\u0394<textarea name=\"_wpcf7_ak_hp_textarea\" cols=\"45\" rows=\"8\" maxlength=\"100\"><\/textarea><\/label><input type=\"hidden\" id=\"ak_js_1\" name=\"_wpcf7_ak_js\" value=\"53\"\/><script>\ndocument.getElementById( \"ak_js_1\" ).setAttribute( \"value\", ( new Date() ).getTime() );\n<\/script>\n<\/p><input type='hidden' class='wpcf7-pum' value='{\"closepopup\":false,\"closedelay\":0,\"openpopup\":true,\"openpopup_id\":16052}' \/><div class=\"wpcf7-response-output\" aria-hidden=\"true\"><\/div>\n<input type=\"hidden\" name=\"trp-form-language\" value=\"es\"\/><\/form>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n<h2 id=\"6-eael-table-of-content\" class=\"wp-block-heading\">4. Heat Treatment of L6 Tool Steel<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">L6 tool steel heat treatment\u00a0process involves four primary steps: preheating, austenitizing (hardening), quenching, and tempering.<\/p>\n\n\n\n<h3 id=\"7-eael-table-of-content\" class=\"wp-block-heading\">4.1 Precalentamiento<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The preheating temperature for L6 tool steel is&nbsp;<strong>1200\u00b0F (650\u00b0C)<\/strong>, with a holding time of&nbsp;<strong>10 to 15 minutes<\/strong>, or until the material is uniformly heated. Avoid prolonged soaking, as it can disrupt molecular structure and cause adverse effects in subsequent processes. For large or complex L6 components, it is recommended to heat slowly within the range of&nbsp;<strong>650\u2013760\u00b0C (1200\u20131400\u00b0F)<\/strong>. If placing the material directly into a furnace already heated to the preheating temperature, it is advisable to first position the material above the furnace to remove chill.<\/p>\n\n\n\n<h3 id=\"8-eael-table-of-content\" class=\"wp-block-heading\">4.2 Hardening (Austenitizing)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The hardening temperature is&nbsp;<strong>1525\u00b0F (830\u00b0C).<\/strong>&nbsp;Some sources list it as 790\u2013870\u00b0C (1450\u20131600\u00b0F) or 790\u2013845\u00b0C (1454\u20131553\u00b0F). This process is influenced by both time and temperature. The soaking time should be sufficiently long to ensure the workpiece is fully heated. During this process, the steel\u2019s microstructure transitions from ferrite-pearlite to austenite, and the alloy carbides dissolve.<\/p>\n\n\n\n<h3 id=\"9-eael-table-of-content\" class=\"wp-block-heading\">4.3 Quenching<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The objective of quenching is to cool the austenite rapidly enough to transform it into a hardened martensitic structure. L6 tool steel is primarily an oil-hardened steel. It has good hardenability and achieves the required hardness through oil quenching. After quenching, parts should be cooled to <strong>125-150\u00b0F (52-65\u00b0C)<\/strong>.<\/p>\n\n\n\n<h3 id=\"10-eael-table-of-content\" class=\"wp-block-heading\">4.4 Tempering<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">When the part temperature drops to&nbsp;<strong>125-150\u00b0F (52-65\u00b0C)<\/strong>, tempering can be performed. Tempering reduces internal stresses, improves steel&#8217;s toughness, and adjusts its hardness. L6 is often tempered once, but multiple tempering is recommended to reduce residual austenite and relieve stress. The holding time is 2 hours per inch (25mm) of cross-section.<br>The resulting hardness can be controlled by varying the tempering temperature.<\/p>\n\n\n\n<p class=\"has-text-align-center wp-block-paragraph\"><strong>Hardness-Tempering Temperature Relationship Table for L6 Steel<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Temperatura de templado<\/strong><\/td><td><strong>Rockwell C<\/strong><\/td><\/tr><tr><td>As quenched<\/td><td>64<\/td><\/tr><tr><td>300\u00b0F\/150\u00b0C<\/td><td>63<\/td><\/tr><tr><td>400\u00b0F\/205\u00b0C<\/td><td>63<\/td><\/tr><tr><td>500\u00b0F\/260\u00b0C<\/td><td>61<\/td><\/tr><tr><td>600\u00b0F\/315\u00b0C<\/td><td>59<\/td><\/tr><\/tbody><\/table><figcaption class=\"wp-element-caption\">Experimental Conditions: 1.

The forging temperature must not fall below 845\u00b0C (1550\u00b0F).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">L6 steel must never be normalized after forging; instead, it should be annealed. L6 tool steel has good hardenability, so it should be cooled from the forging temperature more slowly than by air cooling. L6 steel can be buried in heat-insulating media such as lime, mica, or diatomaceous earth to slow cooling, prevent cracking, and keep the steel in a semi-soft state for subsequent processing.<\/p>\n\n\n\n<h3 id=\"12-eael-table-of-content\" class=\"wp-block-heading\">4.6 Annealing and Stress Relieving<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">L6 steels should not be normalized due to their high hardenability, but instead, they should be annealed after forging and before hardening. The&nbsp;annealing&nbsp;temperature for L6 is&nbsp;<strong>870\u00b0C (1598\u00b0F)<\/strong>. Stress relieving is sometimes performed after rough machining and before final machining, usually by heating to&nbsp;<strong>650-730\u00b0C (1200-1350\u00b0F)<\/strong>&nbsp;to minimize distortion during hardening.<\/p>\n\n\n\n<h2 id=\"13-eael-table-of-content\" class=\"wp-block-heading\">5.
