    May 29, 2015 · The rockwell hardness of M390 at 58 HRC is 58 HRC. Would M390 at 58 HRC ever be M390 at 60 HRC? But to be serious for a minute, if someone wants a tough steel, they should probably look at another steel instead of dropping the hardness below optimal for a steel not meant to be "tough."

  10. Hardness, Brinell Hardness, HBW, HRB, HRC, Rockwell 22

    Rockwell C Hardness: A designation of hardness, usually of steel or Corrosion Resistant Alloys, measured by pressing a specially shaped indenter against a clean prepared surface with a specific force. The machine making the indention also measures the depth of the indention and provides a numerical value for that depth.

  11. Hardness testing methods: Rockwell, Brinell and ...

    Jul 28, 2017 · Its important that engineers specify hardness testing methods correctly to ensure timely heat treatment and avoid costly delays. Common hardness testing methods are introduced below. Rockwell Hardness. This method tests the hardness of steel parts by applying loads to parts via either a tungsten carbide ball or a spheroconical diamond indenter.

  12. Rockwell hardness scales - Sizes

    Rockwell hardness numbers are usually used to describe the hardness of metals, although they are also used for some plastics. Like the Brinell hardness scale, the Rockwell scale is based on measuring the depth of the indentation made by pressing a diamond point, or a ball, into the material.
