The Strength and Durability of 816M40 Steel Grade

The 816M40 steel grade, also known as EN24, is a low alloy steel with high strength and good ductility. It is commonly used in the aerospace, automotive, and oil and gas industries for its excellent mechanical properties and durability.

Mechanical Properties:
– Tensile Strength: 850-1000 MPa
– Yield Strength: 680-800 MPa
– Elongation: 12-14%
– Impact Strength: 25 Joules

Chemical Composition:
– Carbon (C): 0.36-0.44%
– Manganese (Mn): 0.45-0.70%
– Silicon (Si): 0.10-0.35%
– Chromium (Cr): 0.90-1.40%
– Molybdenum (Mo): 0.20-0.35%
– Nickel (Ni): 1.30-1.70%

The 816M40 steel grade is also heat treatable, which allows for further improvement in its mechanical properties. Its high strength and durability make it suitable for components subjected to high stress and heavy loads, such as gears, shafts, and crankshafts.
