Stainless Steel Hardness Test Method and Convenstion Table

99 rows · Stainless steel hardness is usually defined as a property of the surface that represents how resistant the material is to indentation, scratch or wear. A higher hardness means a higher resistance and a higher difficulty to perform machining or any other similar operations on the material.

Stainless Steels - Specifications, Grades and Properties

May 20, 2005 · Hardness of Stainless Steel. Hardness is the resistance to penetration of the material surface. Hardness testers measure the depth that a very hard indenter can be pushed into the surface of a material. Brinell, Rockwell and Vickers machines are used. Each of these has a different shaped indenter and method of applying the known force.
