Properties and applications
The considered steel is intended for production of forgings and finished parts with high temperature resistance. The steel is well heat-treated, the main type of heat treatment is considered to be an improvement. Superior shafts, axles, gears and other similar products can have a large size and a complicated configuration. Weldability of steel is limited.
The main mechanical characteristics of steels of this type that underwent quenching and tempering are:
- The limit of temporary resistance, MPa — 850…900;
- Yield strength, MPa 735 785…;
- Elongation, % — 13 11…;
- The relative narrowing of the cross section % — 39…40;
- Impact strength, kJ/m2 — 55…60;
- Brinell hardness number, HB — 270…320.
