Properties and applications
Alloy steels 18KH2N4VA, 18CrNiMo7−6, 17CrNiMo6 can be subjected to carburizing, improvement and hardening with following tempering. The final physical and mechanical parameters of these steels following:
- Limit strength is 1050 MPa;
- The plastic limit is 800 MPa;
- Elongation — 12%;
- The relative narrowing of the cross section to 50%.
- Hardness after annealing is not higher than HB 270;
- Toughness — 780…1175 kJ/m2 (smaller values correspond to hire with a greater thickness).
After heat treatment, the rolled sheet data of steels used for stamping products, the operation of which is associated with high requirements for strength, wear resistance and fatigue strength. Resistance is maintained up to temperatures of 420…4500 C. the Weldability of steels — limited.
