708M40 steel is a widely used steel grade known for its reliability in tough applications. Its mechanical properties make it a popular choice for components that require high strength and wear resistance.
Mechanical properties:
– Tensile strength: 850-1000 MPa
– Yield strength: 700-850 MPa
– Elongation: 14-18%
– Hardness: 248-302 HB
Chemical composition:
– Carbon (C): 0.36-0.44%
– Silicon (Si): 0.10-0.40%
– Manganese (Mn): 0.60-1.00%
– Phosphorus (P): 0.035% max
– Sulfur (S): 0.040% max
– Chromium (Cr): 0.90-1.20%
– Molybdenum (Mo): 0.20-0.35%
These properties and composition make 708M40 steel suitable for applications such as gears, shafts, crankshafts, and other components for heavy-duty machinery and equipment. Its combination of high strength, good ductility, and good wear resistance makes it a reliable choice for demanding industrial applications.
