Introducing the hardness conversion formula and table for Rockwell Hardness (HRC, HRB) to Brinell Hardness (HB or BHN) by Dandong Foundry in China.
Brinell Hardness (HB) A hardened steel ball of a certain size (generally 10mm in diameter) is pressed into the surface of the material with a certain load (generally 3000kg) and held for a period of time. After the load is removed, the ratio of the load to its indentation area, the ...

Rockwell hardness The rockwell hardness (HR) test was measured using rockwell hardness when the sample was too small or the brinell hardness (HB) was greater than 450. Test method is to use a diamond cone apex Angle of 120 degrees or diameter is 1.59 mm / 3.18 mm steel ball, under ...
