– 0.37- 0.45% Carbon (C)
– 1.40-1.70% Nickel (Ni)
– 0.40-0.70% Chromium (Cr)
– 0.40-0.70% Molybdenum (Mo)
– 0.25% Silicon (Si)
– 0.60-1.00% Manganese (Mn)
These elements contribute to the overall mechanical properties of the steel, including its strength, hardness, toughness, and wear resistance.
The technical properties of 40NiCrMo22 steel grade include:
– Tensile strength: 1000-1300 MPa
– Yield strength: 800-1100 MPa
– Elongation: 11-14%
– Hardness: 270-300 HB
These properties make 40NiCrMo22 steel suitable for applications requiring high tensile strength and good impact resistance, such as gears, shafts, and other heavy-duty machine components.
Understanding the chemical composition and technical properties of 40NiCrMo22 steel grade is important for selecting the appropriate material for specific engineering applications.
