Type 420J2 stainless steel is martensitic steel, which is
inexpensive and very resistant to corrosion. It offers corrosion
resistance both in industrial and domestic environments, as well as
in the mild atmosphere.
It provides resistance to many chemicals, acids, petroleum
products, steam, and household cleaners. Type 420J2 is the
preferred stainless-steel choice for knife manufacturers.
In comparison with 440 grades, stainless-steel type 420J2 provides
better strength and good resistance to impact when it is in
tempered and hardened conditions.
