High carbon stainless steel sheets 7Cr17, 7Cr17Mo, 7Cr17MoV

 

This high-carbon high-chromium martensitic stainless steel is designed to provide stainless properties with excellent hardness.

It has moderate corrosion resistance as-annealed which has permitted its use in mild environments.

In some respects it behaves similarly to tool steels.

 

Type 440A attains a hardness of Rockwell C 56 and maximum toughness when heat treated.

Stainless Type 440A has been used for pivot pins, dental and surgical instruments, cutlery, valve parts, etc.

This steel makes fair permanent magnets.  

 

440A modified 7Cr17MoV stainless steel contains special element vanadium, - a strong carbide former. The vanadium carbides are also very stable and do not dissolve during heat treatment.
