420 stainless steel is a modification of 410, has a higher carbon content to increase hardness, improve strength and give better wear resistance.

420 stainless steel displays good resistance to scaling in continuous service up to 650oC. Its use however at these higher working temperatures results in a substantial drop in tensile strength and hardness, plus a reduction in corrosion resistance.It is therefore not recommended for use at working temperatures above 400oC.
