S460ML steel mill chemical and mechanical property

Standing at a new historical starting point, we adapt to the requirements of supply side structural reform, adhere to the overall strategy of "innovation driven, quality leading, S460ML steel mill quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the S460ML steel mill International leading steel materials supplier.

The defects of S460ML steel mill, wear-resistant plate in rolling process can be divided into raw material defects, surface spot defects, plate shape defects and edge defects. The so-called raw material defects refer to some defects caused by raw materials and kept or remained in the cold rolling process. The defects of raw materials usually include bubbles, inclusions, iron sheet pressing in, raw material scratches and roll marks. The stain defect of wear-resistant plate is mainly caused by the oil on the surface of strip steel and the iron powder produced during rolling, which is left on the surface of strip steel after rolling.

Bridge steel S460ML steel mill is required to have higher strength, toughness, load and impact of rolling stock, and good fatigue resistance, low temperature toughness and atmospheric corrosion resistance. With the development of domestic railway construction towards high speed and heavy load, railway bridge steel developing in the direction of high speed, heavy load, long span, beautiful and novel structure, and full welding, higher requirements are imposed on the properties of steel for bridges. In particular, the development of cross-sea bridges has put forward higher requirements on the corrosion resistance of steel for bridges.

Alloying elements can strengthen the properties of structural steels. S460ML steel mill, Alloy structural steel has suitable hardenability. After proper metal heat treatment, the microstructure is uniform sorbite, bainite or very fine pearlite. Therefore, alloy structural steel has higher tensile strength and yield ratio (generally about 0.85), higher toughness and fatigue strength, and lower ductile brittle transition temperature. Alloy structural steel can be used to manufacture machine parts with larger section size.

S460ML steel mill, 09CuPCrNi-A weather resistant steel is origined in China. Its equivalent grades are JIS SPA-H, BS WR50A, Corten steel, etc. The Cu, P, Cr, Ni are important elements that gave 09CuPCrNi-A weather resistant steel its weathering ability. The Cu content of 09CuPCrNi-A steel is 0.25–0.50, P content is 0.060-0.12, Cr content is 0.30-1.25, Ni content is 0.12-0.65. For 09CuPCrNi-A steel coil ≤ 4mm, the min. yield strength is 310Mpa, min. tensile strength 440Mpa. For 09CuPCrNi-A steel sheets >4mm, the min. yield strength is 345Mpa, min. tensile strength 480Mpa.

We have a professional production team and high-quality production equipment, and we also have a great S460ML steel mill advantage in price, with its own factory, large-scale production to reduce the price. Strictly control each production line to ensure the S460ML steel mill production of high-quality steel plates, steel pipes and other products that meet customer requirements.
