Chemical composition of nm400 material sheet structural

Application of 30CrMnSiA steel, NM400 material:30CrMnSiA steel is generally used after quenching and tempering 30CrMnSiA steel is mainly used to manufacture various important parts with high load and high speed, such as gears, shafts, clutch friction plates, sprocket wheels, grinding wheel shafts, shaft sleeves, bolts, nuts, etc 30CrMnSiA steel is also used for manufacturing wear-resistant parts with low working temperature and variable load welding components, such as blades, valve plates and non corrosive pipes and pipes of high-pressure blowers,NM400 material.

NM400 material,The selection principle of steel plate for high-rise building is: it can not only make the structure safe and reliable, but also can save steel and reduce the cost. Different use conditions should have different quality requirements. In terms of the mechanical properties of steel such as NM400 material, yield point, tensile strength, elongation, cold bending property, impact toughness etc. are the indicators to measure the quality of steel. In the design of steel structure, the appropriate steel should be selected according to the characteristics of the structure. The selection of steel is not only an economic problem, but also related to the safety and service life of the structure.

"Our mill has three production lines:1).2500mm production line (Width: 1600-2300mm, Thickness: 6-30mm, Annual capacity: 1,600,000 Tons; 2).3500mm production line (Width: 2000-3050mm, Thickness: 10-80mm, Annual capacity: 2,000,000 Tons; 3).4300mm production line (Width: 1500-4100mm, Thickness: 6-300mm, Annual capacity: 1,800,000 Tons; The weight of each ingot can reach 44 tons, which is at the leading level in China. In addition, we have a 1700mm hot-rolled coil production line (width range: 900-1550mm, thickness range: 1.2-25.4mm, annual production capacity: 3.5 million tons."
