MATERIAL TESTING
HARDNESS TESTING !"#$%&&'(%)(
This hardness test is used primarily with iron and steel casting. In Brinell test a Brinell Hardness Number (BHN) is determine by pressing a hardened steel ball (10 mm in diameter) into the surface of a specimen with a force of 500 kg and 3000 kg for soft and hard materials, respectively.

A Rockwell test is a penetration test in which a diamond cone is used for hard materials and a hardened steel ball (1/16 inches in diameter) for soft materials. The Rockwell hardness is determined from the depth of penetration and is read directly from a dial.
