Product Usage

Alloy 420 is used for a variety of applications where good corrosion and outstanding hardness is necessary. It is not usually used at temperatures exceeding 800^oF (427^oC) due to quick hardening and loss of corrosion resistance. Examples of applications that use alloy 420 include:Cuttery,Knife blades,Surgical instruments,Needle valves,Shear blades,Scissors,Hand tools,etc.
