Very few steels carry the name and legacy of A-2 tool steel; it is a versatile, air hardening; and characterized by good toughness and excellent non-deforming properties in heat treatment.

A-2 is intermediate in wear resistance compared by many experienced, seasoned pros as being somewhat between O-1 and D-2.

Its effective combination of strength and toughness means guaranteed performance at an affordable price and immediate steel name recognition.

NJSB A2 works like a 1% carbon and arrives full annealed to 12/22Rc, but, when heat treated, will easily pull as high as 62Rc.

With a long outstanding history, when looking for a classic air hardening tool steel, A2 is a winner time and again, year after year.
