Toolman Special Steels is proud to produce and offer A2(1.2363) - This alloy is one of the cold work, medium air hardening type tool steels. It contains chromium and molybdenum with a relatively high (1 %) carbon content and is capable of deep hardening from air quench so as to minimise distortion. It can be hardened through air cooling. A2’s wear resistance lies between that of O1 and that of D2 tool steel so that it is suitable for common materials in many applications
