High carbon martensitic stainless steel sheets 8Cr17, 8Cr17MoV


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

In some respects it behaves similarly to tool steels.

Stainless Type 440B attains a hardness of Rockwell C 58 when heat treated and has been used for cutlery, hardened balls

and similar parts. This steel makes fair permanent magnets.
