NM400 use for bridge thickness is more than 300mm

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 NM400 use for bridge 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 NM400 use for bridge overall strength, competitiveness and anti risk ability of the company.

What does steel S460N stand for? the letter S is short for Structural steel. The number 460 stand for the minimum yield strength is 460MPa for S460N steel. The character N is for Normalised rolling when produce in mill. For steel plates S460N, our minimum order quantity shall be above 10 tons for each thickness. For NM400 use for bridge, S460N hot rolled steel plate specification available, our plate thickness ranges from 8mm to 200mm.

Wear-resistant plates are very easy to understand from the literal. They are steel plates designed for large-area wear conditions. Because of its outstanding wear resistance, wear plates have their own unique uses, such as mining machinery and equipment. Ore processing, transportation of ore, ore and equipment often produce severe friction. NM400 use for bridge, General steel plates cannot be subjected to friction for a long time and are easily damaged. Wear plates are very effective in solving this problem.

NM400 use for bridge Weldability refers to the performance of the weld joint with the expected quality requirements obtained by common welding methods under specific structure and process conditions. Weldability is generally judged by the crack sensitivity and the change of mechanical properties of weld zone. The ability of steel materials to withstand bending without cracking at room temperature is called cold bending. The greater the bending capacity before crack, the better the cold bending performance of the steel material.

The difference between NM400 use for bridge, 10# seamless steel pipe and 20# seamless steel pipe: 1. Chemical composition Chemical composition of 10# seamless steel pipe: C: 0.07-0.13, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.15, Ni: 0.30, Cu: 0.25. Chemical composition of 20# seamless steel pipe: C: 0.07-0.23, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.25, Ni: 0.30, Cu: 0.25 2. Mechanical properties 10# seamless steel pipe: tensile strength: 335 MPa, yield strength: 205 MPa, elongation: 31%. 20# seamless steel pipe: tensile strength: 410 MPa, yield strength: 245 MPa, elongation: 25%.

The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
