A2 tool steel is an air hardened grade steel containing 5% chromium. 

A2 is known for its good toughness and excellent dimensional stability in heat treatment. These characteristics make it a multifunctional tool steel with good performance and price. 

A2 steel is somewhere between oil-hardened and D2 high-carbon, high-chromium tool steel.


Characteristics of A2 tool steel:

Very good without deformation

Deep hardening

High dimensional stability after quenching and tempering

Good machining

High compressive strength
