20 MNCR5

20MnCr5 is a high-strength, tough, and wear-resistant alloy steel widely used in various industrial sectors. It conforms to the European standard EN 1.7147 (DIN 17210) and is known for its ability to achieve high surface hardness while maintaining good core strength. This makes it an ideal material for applications requiring durability and resistance to wear.

Steel Properties

20MnCr5 steel typically exhibits a tensile strength range of 600 to 850 MPa (87 to 123 ksi), depending on the heat treatment condition. The yield strength ranges from 450 to 600 MPa (65 to 87 ksi), and elongation is around 10-16% in the normalized or annealed condition. After heat treatment, the hardness typically ranges from 180 to 250 HB (Brinell Hardness), offering a good combination of strength and wear resistance.

Application

20MnCr5 is extensively used in the automotive industry, especially for manufacturing gears, shafts, camshafts, and transmission components that require high strength and surface hardness. In mechanical engineering, it is utilized for heavy-duty gears, pinions, spindles, and crankshafts that must withstand high loads and stresses. Furthermore, it finds use in general engineering applications, such as bolts, studs, hydraulic fittings, and structural components, where high strength and wear resistance are essential.
