20Cr3MoWV Introduction
20Cr3MoWV is a hardened and tempered alloy steel. It is a kind of Quenched and tempered alloy steel which involves two processes of heat treatment: quenching and tempering. The steel has higher strength and toughness and superior wear resistance compared with other steels. It is generally used for parts that require high strength and fatigue strength.
20Cr3MoWV Chemical composition
20Cr3MoWV steel contains the following elements: carbon, silicon, manganese, chromium, molybdenum, vanadium, nickel, and phosphorus. The carbon content of 20Cr3MoWV is between 0.15-0.20%, the silicon content is between 0.15-0.35%, the manganese content is between 0.80-1.00%, the chromium content is between 1.30-1.50%, the molybdenum content is between 0.15-0.30%, the vanadium content is between 0.02-0.04%, the nickel content is between 0.15-0.25%, and the phosphorus content is between 0.030-0.060%.
20Cr3MoWV Mechanical Properties
The mechanical properties of 20Cr3MoWV steel depend on the heat treatment process. Generally, the mechanical properties of quenched and tempered 20Cr3MoWV Steel is higher than that of non-hardened steel. The yield strength of 20Cr3MoWV steel is 1250-1450MPa, the tensile strength is 1650-1820MPa, and its hardness is between 42-48 HRC.
20Cr3MoWV Applications
20Cr3MoWV steel is widely used for high strength and fatigue strength parts, such as machine tools parts, shafts, gears, pinions, bushings, axles, rods, bolts and other machine parts. It is also used in the automotive and transportation industries for wheels, shafts, and other parts that require high strength. 20Cr3MoWV steel is also used in the manufacturing of agricultural machinery and construction machinery. This steel is also used in the production of machines used in the production of paper, textile, rubber, and other industrial products.
Conclusion
20Cr3MoWV steel is a quenched and tempered alloy steel. It has high strength and fatigue strength and good wear resistance. It is widely used in various industries, such as automotive, agricultural machinery, and construction machinery. The mechanical properties of 20Cr3MoWV steel depend on the heat treatment process. It can be used to make machine tools parts, shafts, gears, pinions, bushings, axles, rods, bolts and other machine parts.
