Rockwell hardness (HR) is an indentation hardness test that is determined with a hard steel ball, that is forced into the specimen surface. The test is accomplished by bringing the specimen into contact with the penetrator and allowing the penetrator to be slowly forced into the specimen surface by a series of weights acting through a system of levers. After the load is released, a dial pointer or LED screen indicates the hardness number.
