Since its establishment, the company has always adhered to the enterprise spirit of "solid feet and lofty ideals, dare to create and take responsibility, and dedicate to work". After years of careful management, the company has achieved the double improvement of S550MC steel for car parts capital strength and scale expansion, gained wide recognition and general praise from all walks of life, further realized specialized and large-scale operation and optimized allocation of resources, and effectively improved the S550MC steel for car parts overall strength, competitiveness and anti risk ability of the company.

Q355NH material is a Chinese steel grade to GB/T 4171-2008 atmospheric corrosion resisting structural steel. There are five steel levels under Q355NH: Grade A, B, C, D, and E. Q355NH structural steel sheet is mainly used in vehicles, containers, construction, towers or other structural parts and other structures. It has good resistance to atmospheric corrosion. We supply S550MC steel for car parts, Q355NH steel plates thickness less than 120mm.

The S550MC steel for car parts, wear-resistant steel plate has the characteristics of high strength, impact resistance, beautiful appearance, high performance, high efficiency, and high cost performance, and has a broad application prospect. The wear-resistant steel plate adopts a combination of plate and beam as a whole to carry a fully welded structure. Since the plate used is thinner, in order not to reduce the strength of the plate and reduce the deformation, try to use spot welding to form a cavity, which is the structural feature and technical key of the wear-resistant steel .

Although S550MC steel for car parts, low carbon steel has excellent plasticity, toughness and processing technology, its strength is low and its corrosion resistance is not strong enough. On the basis of ordinary low carbon steel, the low alloy structural steel with high strength, high toughness, good weldability and corrosion resistance can be obtained by adding a small amount of alloy elements and the total amount is less than 3%. Manganese is the main additive element in this kind of steel, and its content is about 1% ~ 1.6%.

A335 P22 steel pipe belongs to ferrite alloy steel nominal pipe for high temperature use. Chemical composition of A335 P22 steel pipe: C 0.10-0.20, Mn 0.30-0.80, P ≤ 0.025, S ≤ 0.025, Si 0.10-0.50, Mo 0.44-0.65. Mechanical properties of A335 P22 steel pipe: tensile strength 415mpa, yield strength 205 MPa. S550MC steel for car parts, A335 P22 steel pipe is characterized by good process performance, less sensitivity to the heating temperature of heat treatment, good welding performance, good plasticity, and low strength, especially the high temperature rupture strength is lower than 12Cr1MoV steel. When used at the same temperature and stress, its wall thickness is about 30% thicker than 12Cr1MoV Steel.
