SKD61 is the Japanese JIS equivalent of H13 steel.<\/p>\n      <p>H13 is widely used in American and international specifications. SKD61 is used in Japanese and Asian market specifications.

The &#8220;4&#8221; indicates about 0.4% carbon. &#8220;Cr5&#8221; indicates about 5% chromium. &#8220;Mo&#8221;, &#8220;Si&#8221;, and &#8220;V1&#8221; indicate molybdenum, silicon, and vanadium additions.<\/p>\n\n      <div class=\"aobo-table-wrap\">\n        <table class=\"aobo-table\">\n          <thead>\n            <tr><th>Chinese Grade<\/th><th>Common International Equivalent<\/th><\/tr>\n          <\/thead>\n          <tbody>\n            <tr><td>4Cr5MoSiV1<\/td><td>H13 \/ 1.2344 \/ SKD61 \/ X40CrMoV5-1<\/td><\/tr>\n          <\/tbody>\n        <\/table>\n      <\/div>\n\n      <p>For export communication, Chinese suppliers often write this material as H13 \/ 1.2344 \/ SKD61 \/ 4Cr5MoSiV1.

UNS T20813 is the Unified Numbering System designation for H13 tool steel.<\/p>\n      <p>H13 is the common grade name. T20813 is the UNS identification code for the same tool steel grade.<\/p>\n\n      <div class=\"aobo-table-wrap\">\n        <table class=\"aobo-table\">\n          <thead>\n            <tr><th>Designaci\u00f3n<\/th><th>System<\/th><th>Significado<\/th><\/tr>\n          <\/thead>\n          <tbody>\n            <tr><td>H13<\/td><td>AISI \/ SAE \/ ASTM<\/td><td>Common grade name<\/td><\/tr>\n            <tr><td>T20813<\/td><td>UNS<\/td><td>Unified material identification code<\/td><\/tr>\n          <\/tbody>\n        <\/table>\n      <\/div>\n\n      <p>The &#8220;T&#8221; in UNS T20813 identifies the material as a tool steel. In technical documents, UNS T20813 helps avoid confusion when multiple grade-naming systems are used together.<\/p>\n      <p>If a drawing specifies UNS T20813, a supplier can normally quote H13 tool steel, provided the material meets the required standard, condition, inspection, and documentation requirements.<\/p>\n\n      <h2>Why These Grades Are Treated as H13 Equivalents<\/h2>\n      <p>H13, 1.2344, SKD61, 4Cr5MoSiV1, X40CrMoV5-1, and UNS T20813 are treated as equivalents because they are based on the same chromium-molybdenum-vanadium hot-work steel design.<\/p>\n      <p>A typical H13 composition is:<\/p>\n\n      <div class=\"aobo-table-wrap\">\n        <table class=\"aobo-table\">\n          <thead>\n            <tr><th>Elemento<\/th><th>Rango t\u00edpico<\/th><\/tr>\n          <\/thead>\n          <tbody>\n            <tr><td>Carb\u00f3n<\/td><td>0.32\u20130.45%<\/td><\/tr>\n            <tr><td>Cromo<\/td><td>4.75\u20135.50%<\/td><\/tr>\n            <tr><td>Molibdeno<\/td><td>1.10\u20131.75%<\/td><\/tr>\n            <tr><td>Vanadio<\/td><td>0.80\u20131.20%<\/td><\/tr>\n            <tr><td>Silicio<\/td><td>0.80\u20131.20%<\/td><\/tr>\n            <tr><td>Manganeso<\/td><td>0.20\u20130.60%<\/td><\/tr>\n          <\/tbody>\n        <\/table>\n      <\/div>\n\n      <p>This alloy balance gives H13 steels good hot strength, toughness, hardenability, and resistance to thermal fatigue. Chromium supports hardenability. Molybdenum improves resistance to softening at high temperatures. Vanadium contributes to wear resistance and tempering resistance.<\/p>\n      <p>The final performance still depends on steelmaking quality, forging quality, section size, heat treatment, and inspection requirements. This is why equivalent grades should be confirmed by both grade name and order specification.<\/p>\n\n      <h2>Is 1.2343 the Same as H13?<\/h2>\n      <p>No. 1.2343 is not the same as H13 \/ 1.2344.<\/p>\n      <p>This distinction is important because 1.2343 and 1.2344 are easy to confuse. 1.2344 is the DIN \/ EN equivalent of H13. 1.2343 is the DIN \/ EN equivalent of H11.<\/p>\n\n      <div class=\"aobo-table-wrap\">\n        <table class=\"aobo-table\">\n          <thead>\n            <tr><th>Calificaci\u00f3n<\/th><th>Common Equivalent<\/th><th>Relationship to H13<\/th><\/tr>\n          <\/thead>\n          <tbody>\n            <tr><td>1.2344<\/td><td>H13<\/td><td>Direct equivalent<\/td><\/tr>\n            <tr><td>1.2343<\/td><td>H11<\/td><td>Related hot-work tool steel, but not the same grade<\/td><\/tr>\n          <\/tbody>\n        <\/table>\n      <\/div>\n\n      <p>H11 and H13 are both chromium-based hot-work tool steels, but they are not identical.
