2021-6-15 · What is Hardness of Steels Definition. Hardness of Steels. High-carbon steel has approximately 0.60 to 1.00% carbon content. Hardness is higher than the other grades but ductility decreases. Brinell hardness of high-carbon steel is approximately 200 MPa. In the figure, there is the iron–iron carbide (Fe–Fe3C) phase diagram.Hardening of Metals: 4 Methods Metallurgy,2 天前 · The resultant microstructure of a fully hardened steel should consist of martensite. In practice, it is very difficult to have a completely martensitic structure by hardening treatment. Some amount of austenite is generally present in the hardened steel. This austenite existing along with martensite is referred to as retained austenite.
2016-5-16 · It is the general characteristic of the steel materials which shows that processes which increase their YS also decrease their ductility.
