Hardenability of Steel: 4 Factors | Metallurgy
The following points highlight the four main factors affecting the hardenability of steel. The factors are: 1. Grain Size 2. Austenitising Temperature and Time 3. Carbon Content of the Steel 4. Alloying Elements in Steel. Factor # 1. Grain Size: Grain boundaries are the preferential nucleation sites for ferrite and pearlite. If austenitic grain size is large, the grain boundary [...]
