Everything You Need to Know About 35CrMo4 Steel Grade

[ad_1] 35CrMo4 is a low-alloy steel with good tensile and yield strength as well as excellent toughness and fatigue strength. It is commonly used in the manufacturing of automotive, heavy engineering, and industrial equipment. Here is everything you need to know about the 35CrMo4 steel grade:

Mechanical Properties:
– Tensile strength: 800-1000 MPa
– Yield strength: 650 MPa
– Elongation: 15%
– Hardness: 217 HB
– Impact strength: 100 J

Technical Properties:
– Density: 7.85 g/cm3
– Thermal conductivity: 42 W/mK
– Specific heat capacity: 460 J/kgK
– Electrical resistivity: 0.22 x10^-6 Ωm
– Modulus of elasticity: 210 GPa

Chemical Composition:
– Carbon (C): 0.32-0.40%
– Silicon (Si): 0.17-0.37%
– Manganese (Mn): 0.50-0.80%
– Phosphorus (P): 0.035% max
– Sulfur (S): 0.04% max
– Chromium (Cr): 0.80-1.10%
– Molybdenum (Mo): 0.15-0.25%

The combination of these mechanical, technical, and chemical properties makes 35CrMo4 steel grade suitable for a wide range of applications, including the manufacturing of gears, shafts, and other components subjected to high stress and fatigue. When heat treated, it can also exhibit good wear resistance and improved strength properties.
