Hardness Testing
Hardness testing for steel is based upon applying pressure to the steel surface and measuring the depth of the indentation. The three major measurement systems are :-
The Brinell hardness test consists in indenting the metal surface with a 10-mm-diameter steel ball at a load of 3,000 kg mass (∼29400 N). For soft metals the [...]
Hardness Testing Hardness testing for steel is based upon applying pressure to the steel surface and measuring the depth of the indentation. The three major measurement systems are :- The Brinell hardness test consists in indenting the metal surface with a 10-mm-diameter steel ball at a load of 3,000 kg mass (∼29400 N). For soft metals the load is reduced to 500 kg to avoid too deep an impression, and for very hard metals a tungsten carbide ball is used ... Read More
