20 MNCR5
Carbon Steel 20MnCr5 is a commonly used alloy steel known for its high strength, toughness, and wear resistance. It belongs to the European standard EN 1.7147 (DIN 17210) and is widely utilized in various industrial applications where high surface hardness and good core strength are required. Let's delve into the specifics of 20MnCr5 steel:
Steel Properties
Tensile Strength: Typically ranges from 600 to 850 MPa (87 to 123 ksi) depending on the heat treatment condition.
Yield Strength: Varies widely based on the heat treatment and can range from 450 to 600 MPa (65 to 87 ksi).
Elongation: Around 10-16% in the normalized or annealed condition.
Hardness: Typically, the hardness after heat treatment ranges from 180 to 250 HB (Brinell Hardness).
Application
Automotive Industry: Gears, shafts, camshafts, and other transmission components.
Mechanical Engineering: Heavy-duty gears, pinions, spindles, and crankshafts.
General Engineering: Bolts, studs, hydraulic fittings, and structural components requiring high strength and wear resistance.
