Properties and application
Medium-carbon structural alloy steel of the considered grades is characterized by good machining ability. The steels are used for parts whose operating conditions require high strength and wear resistance with sufficient toughness of the core. Such parts include critical gears, gears, shafts,
Mechanical characteristics of volumetric rolled steels are as follows:
- ultimate strength, MPa - 1250 ... 1450;
- ultimate ductility, MPa - 750...900;
- Relative elongation, %, not less than 11...12;
- Relative narrowing, % - 45...50;
- Brinell hardness, HB - not more than 248.
