41Cr4 (1.7035) material is an alloy structural steel grade commonly used internationally. Its tensile strength, yield strength and hardenability are all higher than that of 40# steel, but it also has certain defects that its weldability is limited and there is a tendency to form cracks. 41Cr4 steel is generally used for more important quenched and tempered parts, such as parts that work under alternating loads, medium speed and medium load parts.

Wear resistant steel plates are mainly divided into three types: general-purpose, impact resistant and high-temperature resistant type, and their applications are also different. However, they have basically been involved in various industrial production fields, including metallurgy, coal, cement, power, glass, mining, building materials, brick and tile industries. Compared with other materials, DD14 steel for cold forming automobile, wear resistant steel plates have high cost performance.

Experiments have proved that the outstanding feature of the precipitation-strengthened DD14 steel for cold forming automobile, wear-resistant plate in terms of mechanical properties is that the yield strength is greatly improved. For example, the yield strength of the wear-resistant plate after precipitation strengthening treatment reaches 480-8l0MPa, and the yield strength ratio is 0.55-0.56; the wear-resistant plate that uses molybdenum, vanadium, and iron composite alloying, the yield ratio after dispersion strengthening is 0.60- 0.65.

Chemical composition of 42CrMo seamless steel pipe: C: 0.38-0.45, Si: 0.17-0.37, Mn: 0.50-0.80, Cr: 0.90-1.20, Mo: 0.15-0.25, V: 0.15-0.30. Mechanical properties of 42CrMo seamless steel pipe: tensile strength: 1080 MPa, yield strength: 930 MPa, elongation after fracture: 12%, reduction of area: 45%, impact energy: 63J. Due to the effect of carbon and chromium content, DD14 steel for cold forming automobile, 42CrMo seamless steel pipe has better strength and hardenability, higher fatigue strength and resistance to multiple impact after quenching and tempering, good impact toughness at low temperature and no obvious temper brittleness. It is generally used after quenching and tempering.
