Excellent Fatigue Strength And Wear Resistance Scr440 Steel Supply - China

SCr440 steel is an excellent alloy structural steel with high fatigue strength and good wear resistance.

It is widely used in the manufacture of medium-speed and medium-load mechanical parts, such as gears, shafts, worms, spline shafts, etc.

Its performance characteristics and technical parameters are as follows: Mechanical properties of SCr440 steel

- Tensile strength: ≥980 MPa

- Yield strength: ≥785 MPa

- Elongation: ≥9%

- Sectional shrinkage: ≥45%

- Impact energy: ≥47 J

- Impact toughness value: ≥59 J/cm²

- Hardness: ≤207 HB in annealing state, and can reach about 54 HRC after surface quenching These properties show that SCr440 steel has high strength and toughness, can withstand large alternating loads, and exhibits excellent fatigue strength.

After quenching and tempering treatment, SCr440 steel has excellent comprehensive mechanical properties, good machinability, and outstanding wear resistance, which is suitable for manufacturing parts requiring high wear resistance and fatigue strength.

In summary, SCr440 steel, with its excellent fatigue strength and wear resistance, combined with good toughness and machinability, has become an ideal material for manufacturing medium-speed, medium-load mechanical parts.

Its performance can be further improved through reasonable heat treatment process to meet the use requirements under complex working conditions.
