080M46 Steel Grade: An Overview of its Composition and Mechanical Properties

[ad_1] 080M46 is a medium carbon engineering steel that is known for its excellent strength, toughness, and hardenability. The steel is commonly used in applications requiring high tensile strength and good wear resistance.

Chemical Composition:
– Carbon (C): 0.43-0.50%
– Silicon (Si): 0.10-0.40%
– Manganese (Mn): 0.60-0.90%
– Phosphorus (P): max 0.035%
– Sulfur (S): max 0.040%

Mechanical Properties:
– Tensile Strength: 700-850 MPa (megapascal)
– Yield Strength: 460 MPa (minimum)
– Elongation: 14% (minimum)
– Reduction in Area: 40% (minimum)
– Hardness: 201-255 Brinell

Some important technical properties of 080M46 steel include good weldability, machinability, and resistance to deformation. It can be readily heat treated to achieve higher hardness and strength.

Common uses of 080M46 steel include gears, chain links, shafts, and other highly stressed components in machinery and automotive industries. It is often used as a replacement for higher cost alloy steels due to its similar properties at a more affordable price.
