Delving Into the Mechanical Properties of 14CrMo45 Steel Grade

The chemical composition of 14CrMo45 steel grade typically includes:

– Carbon (C): 0.10-0.17%
– Silicon (Si): 0.10-0.35%
– Manganese (Mn): 0.40-0.70%
– Phosphorus (P): ≤ 0.035%
– Sulfur (S): ≤ 0.035%
– Chromium (Cr): 0.85-1.15%
– Molybdenum (Mo): 0.45-0.65%
– Nickel (Ni): ≤ 0.30%
– Copper (Cu): ≤ 0.30%

These elements contribute to the overall strength, toughness, and corrosion resistance of the steel.

The mechanical properties of 14CrMo45 steel grade include:

– Ultimate Tensile Strength: 370-490 MPa (Mega Pascals)
– Yield Strength: ≥ 220 MPa
– Elongation: ≥ 22%
– Reduction in Area: ≥ 55%
– Hardness: ≤ 170 HB (Brinell Hardness)

These mechanical properties determine the ability of the steel to resist external forces, withstand deformation, and maintain structural integrity under different conditions.
