ASTM A681 specification covers the chemical, mechanical, and physical requirements for available wrought alloy tool steel products, which include hot or cold finished steel bar, steel plate, steel sheet, strip, rod, wire, or forgings etc.
Material in accordance with ASTM A681 specification is classified by chemical composition. There are Hot Work Tool Steel, Cold Work Tool Steel, Shock-Resisting Steels, Special-Purpose Tool Steels, Plastic Mold Tool Steel. Common steel grades: H11, H13, A2, D2, D3, O1, P20 etc.
AISI S7 tool steel is a shock-resistant air hardening steel. AISI S7 steel has exceptional impact properties plus the highest hardenability of shock resisting grades of tool steel.
AISI O2 Steel is an oil hardening tool steel supplied in the annealed condition. ASTM O2 steel is widely used for universal use. It's similar to AISI O1 grade tool steel, with addition of Mo element.
AISI D6 tool steel is a 12% chromium alloy cold work tool steel.We supply good quality of AISI D6 and equipvalent DIN 1.2436/X210CrW12 or JIS SKD2 steels.
ASTM/AISI A2 tool steel is a versatile, air hardening chromium alloy tool steel that replaces O1 tool steel when safer hardening, less distortion and increased wear resistance are required.
AISI H12 steel is a 4.75~5.5% chromium, general-purpose hot work tool steel. ASTM/AISI H12 Steel is a deep-hardening, air-hardening steel that exhibits minimal size change during heat treatmnet.
H10 Tool Steel is one chromium hot-work tool steel that exhibits excellent resistance to softening at elevated temperature. H10 tool steel is recommended for difficult hot work tooling applications.
AISI P20 Steel Plate Material is a versatile, low-alloy tool steel that is characterized by good toughness at moderate strength levels. The special purpose mold steel P20 steel plate is commonly used for plastic injection mold cavities and tooling.
AISI D2 tool steel is a high carbon, high chromium tool steel (12% chrome) with extremely high wear resisting properties, heat treatable to 60-62 Rc. D2 is very wear resistant but not as tough as lower alloyed steels.
H13 Tool Steel is chromium hot-work tool steels. Due to H13 steel excellent combination of high toughness and fatigue resistance, AISI H13 hot work tool steel is used more than any other tool steel in tooling applications.
