Gear Hardness Technology
between AfSI 4140, a leanalloy steel withpoor hardenability, and AI;S~4340. a rich alloy steel. In order to compare the hardenability of a material. end quench (Jominy) values are widely used as an indicator of a steel's hardenability, Since the quench is so critical to the resulting microstructure, it is necessary to verify the results with an ...
