remastersys, astm a681 type a2AISI A2 tool steel is one of A group cold works steel in ASTM A681 standard. 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 type A2 steel is intermediate in wear resistance between O1 oil-hardening tool steel and high-carbon, high-chromium tool steel. AISI Steel A2 is heat treatable and will offer a hardness in the range 57-62 HRC. ASTM grade A2 steel delivers good toughness with medium wear resistance and is relatively easy to machine.
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.

Steels of the type A2, A3, A4, A6, A7, A8, A9, and A10 form air-hardening, medium alloy, cold work steels or group A steels. Sufficient amounts of manganese, molybdenum and chromium present in group A steels provide full hardness in sections comprising thickness of at least 100 mm (4 in.) in diameter when air cooled.
A2 Flat Ground, is an air hardening chromium alloy die steel that replaces O1 Flat Ground when safer hardening, less distortion and increased wear resistance are required. Characteristics of A2 Flat Ground include - good machinability, high compressive strength, very good non-deforming properties, deep hardening, and high dimensional stability , astm a681 type a2
A2 is an AOD air hardened tool steel that has good toughness and excellent dimensional control after heat treatment. This grade has improved wear resistance as compared to the O series (oil hardened) tool steels.
Products Tool Steel Size Tolerances. Tool Steel is stocked to tolerances per ASTM A681-08. Round bars are turned to plus tolerances to allow customers to finish to the nominal diameter. Flat bars are ground on the thickness to plus tolerances ranging from +.015 to +.090 depending on the thickness of the material.

The actual grade of the material is ASTM A681(0-1). What I have found thus far is that ASTM does not publish strength or hardness specifications for A681 (and most other) tool steels. Their very purpose is to be made into a tool of some sort and then heat treated to obtain the desired mechanical properties.
The A2 tool steel sheet has been precision ground, meets American Society for Testing and Materials International ASTM A681 specifications, and has an oversized tolerance. The A2 tool steel grade has better wear resistance than O1 and W1 tool steels, and maintains good dimensional stability when hardened in air following heat treatment.

The O1 tool steel sheet has been precision ground and polished, meets American Society for Testing and Materials International ASTM A681 specifications, and has a standard tolerance. The O1 tool steel grade has better machinability than A2 tool steel.
ASTM A681 T20813 / H13 is a kind of Hot Work Die Steel who has a better hot strength, high toughness, in the mid level temperature. ASTM A681 T20813 / H13 Hot Work Die Steel usually use to manufacture the compression mold for aluminium casting, the tools and core , bar, press forging die, plasic mould and so on for hot extrusion and tresis .
ASTM A681 - 08 flanges, Pipe Fitting, Steel Pipe, Heat Exchanger and Reducer, Gasket, Tee, Pipe Fitting, Tube Plate, have all specifications. With many yeas production experience, strict control ASTM 11Q chemical composition and ASTM 11Q mechanical properties.
AISI A2 is an air-hardening tool steel containing 5 pct chromium. It replaces O1 when safer hardening, better dimensional stability, and increased wear-resistance are required. Use for dies, punches, and similar forming and blanking tools as recommended for Type O1, but where less distortion in heat-treatment or better wear-resistance is required.
