Understanding The Brinell Hardness Scale Developed in 1900 by Swedish engineer Johan August Brinell, the Brinell hardness scale is used to test the hardness of metal. The Brinell test is one of the main three tests of hardness in the steel industry, along with the Vickers and the Rockwell hardness tests. The method involves indenting a test material with a hardened steel or carbide ball that is 10 mm in diameter with a load of 3000......

Case Hardening Of Steel Gives It The Edge In Some Situations Case hardening is a processing method used to harden low-carbon steel. Carbon and alloy steels are most often case hardened. You will find this true in applications such as knife blades and other similar uses.In this process, the surface of the steel that is treated has carbon added to it. The result is an outer layer of steel that is hard, with an inside core that remains softer and pliable.Case...... Similar Editorial : by sfrom. | Source : Science Project Ideas
