From Strength to Resistance: How 13CrMo4-4 Steel Benefits Construction

The specification of 13CrMo4-4 steel includes its mechanical properties and chemical composition, both of which contribute to its benefits in construction applications.

Mechanical Properties:
– Tensile Strength: 440-590 MPa
– Yield Strength: 290-490 MPa
– Elongation: 22-28%
– Impact Toughness: ≥35 J/cm²
– Hardness: ≤ 195 HB

Chemical Composition:
– Carbon (C): 0.08-0.18%
– Silicon (Si): ≤0.35%
– Manganese (Mn): 0.40-1.00%
– Phosphorus (P): ≤0.025%
– Sulfur (S): ≤0.020%
– Chromium (Cr): 0.70-1.15%
– Molybdenum (Mo): 0.40-0.60%
– Nickel (Ni): ≤0.30%

The mechanical properties of 13CrMo4-4 steel, such as high tensile and yield strength, indicate its ability to withstand heavy loads and stresses in construction. Its high impact toughness ensures its durability and resistance to cracking under dynamic loads.

The chemical composition of 13CrMo4-4 steel, with a balance of elements like carbon, silicon, and manganese, enhances its strength and hardenability. Chromium and molybdenum provide good corrosion resistance and improve its high-temperature strength and creep resistance. The low sulfur and phosphorus content make it suitable for welding and prevent brittleness.

Overall, the combination of its mechanical properties and chemical composition makes 13CrMo4-4 steel a reliable and effective material for construction applications, particularly in high-temperature and high-stress environments.
