Product Description
A2 Tool Steel /1.2363/X100CrMoV5/SKD12 - Versatile Cold Work Steel
AISI A2 Tool Steel is an air-hardening chromium alloy tool steel classified under the 'A' group in ASTM A681. It is a versatile steel that offers safer hardening, reduced distortion, and improved wear resistance compared to O1 tool steel. A2 steel strikes a balance between the wear resistance of O1 oil-hardening tool steel and the high carbon, high chromium content of D2 tool steel.
Heat treatable, A2 tool steel offers a hardness range of 57-62 HRC and provides good toughness with medium wear resistance. It is relatively easy to machine and is widely used in applications that require both wear resistance and toughness, making it ideal for a variety of cold work tooling applications.

AISI A2 Tool Steel | 1.2363 | X100CrMoV5 | SKD12 - Heat Treatment
Stress Relieving
After grinding or machining, heat to 670-700°C and hold for at least 2 hours per 25mm thickness, then cool in the furnace to reduce cracking risks.
Annealing
Heat to 899°C (1650°F), hold for 2 hours per inch of thickness, then cool slowly to 650°C (1200°F). Reheat to 732°C (1350°F) for 3 hours and cool slowly to room temperature.
Hardening
-
Preheating: 1200-1380°F (650-750°C)
-
Austenitizing: 1700-1780°F (925-970°C), typically around 1720-1760°F (940-960°C).
Tempering
Heat to the desired temperature and hold for 25 minutes per cm of thickness. Temper at 200°C for hardness and strength balance, or at 350°C for more strength. Minimum holding time: 2 hours per inch of thickness.
Quenching
Quench in martempering bath at 360-430°F (180-220°C) or 840-1020°F (450-550°C), then cool in air. For small tools, use oil.
Nitriding
For surface hardness and wear resistance:
Nitrocarburizing
2-hour treatment at 1060°F (570°C) gives surface hardness of 900 HV1 with a case depth of 0.0004-0.0008" (10-20 µm).
This heat treatment ensures AISI A2 Tool Steel has optimal hardness, toughness, and wear resistance for various cold work applications.
