AISI 420 UNS S42000 Cold Rolled Stainless Steel Strip Coil And Sheet
Grade 420 is a “descendant” of the martensitic grade which was invented by Harry Brearley in Sheffield in 1913.
It is a hardenable stainless steel used for its basic corrosion resistance, high strength and wear resistance.

Stainless 420 grade combines the following characteristics:
Controlled balance of mechanical properties by hardening and tempering
High wear resistance
Cost effectiveness due to low chromium content and absence of nickel
Magnetic
Thermal expansion comparable to carbon steel
Not easy to weld
