311-Type 7 steel is a medium carbon, low alloy steel with a typical chemical composition of 0.30% carbon, 1.0% manganese, 0.15% silicon, 0.025% phosphorus, and 0.025% sulfur. It also contains small amounts of other alloying elements such as chromium, molybdenum, and nickel.
The mechanical properties of 311-Type 7 steel typically include a tensile strength of 600 MPa, yield strength of 520 MPa, and an elongation of 16%. This steel grade is known for its high strength, toughness, and wear resistance, making it suitable for applications in industries such as automotive, construction, and manufacturing.
Its applications include manufacturing of heavy duty machinery components, gears, axles, crankshafts, and shafts. Additionally, it is used in the production of high strength fasteners, cutting tools, and steel plates for structural applications. Due to its high strength and toughness, 311-Type 7 steel is preferred for applications that require a combination of strength and durability.
