Understanding the Strength and Durability of 36CrNiMo4 Steel Grade

[ad_1] The 36CrNiMo4 steel grade is a low-alloy steel known for its high strength and durability. It is commonly used in the manufacturing of heavy-duty components such as gears, shafts, and crankshafts.

Mechanical Properties:
– Tensile Strength: 900-1100 MPa
– Yield Strength: 650-800 MPa
– Elongation: 12-15%
– Hardness: 248-302 HB

Technical Properties:
– Density: 7.85 g/cm3
– Young’s Modulus: 210 GPa
– Poisson’s Ratio: 0.3

Chemical Composition:
– Carbon (C): 0.32-0.40%
– Silicon (Si): 0.4%
– Manganese (Mn): 0.5-0.8%
– Phosphorus (P): 0.025% max
– Sulfur (S): 0.02% max
– Chromium (Cr): 0.9-1.2%
– Nickel (Ni): 0.9-1.2%
– Molybdenum (Mo): 0.15-0.30%

These properties make 36CrNiMo4 steel grade highly suitable for applications requiring high strength, good toughness, and high fatigue strength.
