its condition and heat treatment. Supplied H13 is normally annealed for machining, usually around 220&ndash;241 HB. After quenching, standard sections may reach about 51&ndash;54 HRC, while large sections can show lower core hardness.<\/p>\n      <p>After tempering, finished H13 tools are commonly adjusted within about 38&ndash;55 HRC. Many hot-work tools work around 40&ndash;48 HRC, with lower hardness often used for heavy shock and higher hardness used where wear resistance is more important.<\/p>\n      <p>Final hardness can change with section size, austenitizing temperature, cooling rate, tempering practice, and test position. For most H13 tooling, the target is balanced hardness, not maximum hardness.<\/p>\n      <p>Aobo Steel supplies H13 tool steel in an annealed condition for bulk orders, including round bar, flat bar, plate, and forged block.

Large inserts are often kept at a lower hardness to reduce the risk of cracking, while smaller inserts can be made harder when wear resistance is more important.<\/p>\n      <p>For forging dies, impact severity is the main concern. Hammer forging normally requires lower hardness than press forging because the loading is more sudden and severe. If hardness is pushed too high, the die may crack before wear becomes the main problem.<\/p>\n      <p>For extrusion tooling, the tool function matters. Dies, mandrels, dummy blocks, rams, liners, and containers should not automatically be assigned the same hardness, as they experience different thermal and mechanical loads.<\/p>\n      <p>A simple selection rule is when wear and plastic deformation dominate; a higher working hardness may help. When cracking, chipping, severe impact, or thermal fatigue dominate, a lower or more balanced hardness is usually safer.<\/p>\n    <\/main>\n\n    <section class=\"aobo-final-cta\">\n      <div>\n        <h2>Need H13 Steel for Hot-Work Tooling?<\/h2>\n        <p>Send your required grade, size, quantity, condition, and application.
