– Carbon (C): 0.40-0.45%
– Chromium (Cr): 1.50-1.80%
– Aluminum (Al): 0.70-1.20%
– Molybdenum (Mo): 0.40-0.60%
In addition to these major components, the composition may also include small amounts of other elements such as manganese, phosphorus, sulfur, and silicon.
The mechanical properties of 41CrAlMo7 steel grade are as follows:
– Tensile strength: 900-1100 MPa
– Yield strength: 700-850 MPa
– Elongation: 13-17%
– Hardness: 270-320 HBW
These properties make 41CrAlMo7 steel grade suitable for applications that require high strength, good toughness, and resistance to wear and fatigue. It is commonly used in the manufacturing of gears, shafts, and other components in automotive, aerospace, and machinery industries.
