42CrMo4 is a European standard high-strength alloy structural steel, also known as DIN 1.7225 steel.
42CrMo4 steel plate features:
High strength: 42CrMo4 alloy steel after quenching and tempering treatment, has a high yield strength and tensile strength, can withstand greater pressure and load.
Good toughness: 42CrMo4 alloy steel toughness is better, not easy to crack, can adapt to some impact and vibration of the working environment.
Good wear resistance: The alloying elements contained in 42CrMo4 alloy steel can form some carbides, improve the wear resistance of steel, and are often used to manufacture some wear-resistant parts that need to be used for a long time.
The chemical composition of 42CrMo4 includes carbon (C), silicon (Si), sulfur (S), manganese (Mn), phosphorus (P), chromium (Cr), and molybdenum (Mo). Among them, the carbon content is between 0.38 and 0.45%, the silicon content is not more than 0.40%, the allowable residual content of sulfur and phosphorus is not more than 0.035%, the chromium content is between 0.90 and 1.20%, and the molybdenum content is between 0.15 and 0.30%.
42CrMo4 steel plate application:
Automotive industry: 42CrMo4 special steel is often used in automotive parts, such as engine parts, suspension systems and drive shafts. Its excellent wear resistance and high strength help to improve the performance and life of the car.
Aerospace sector: In the aerospace sector, the high material requirements make 42CrMo4 ideal for the manufacture of aircraft and rocket parts. Its superior strength and wear resistance ensure the safety and reliability of the aircraft.
Mechanical manufacturing: 42CrMo4 alloy steel is often used to manufacture high-precision and high-load mechanical parts, such as gears, shaft parts, bolts, etc. At the same time, it is also suitable for the manufacture of integrated forming electrical and electronic molds.
