Effect of the quenching cooling rate on the properties of steel 15KhGNMFA
- 30 Downloads
Mechanical properties of steel 15KhGNMFA after quenching at cooling rates ranging from 5 to 50,000 K/h are studied. Three ranges of cooling rates ensuring stable properties of the steel are determined. Recommendations are given as to the use of steel 15KhGNMFA for commercial production of components of high-load presses and other articles in accordance with the strength requirements.
