nm400 weathering steel professional supplier in China

The company has always adhered to the principle of "genuine goods at low prices", put an end to the sale of fake and shoddy NM400 weathering steel products, do not deceive customers, treat customers in good faith, truly consider for customers and give advice. To provide reference opinions, and to treat customers with integrity. Consequently, we have won a lot of NM400 weathering steel stable cooperated customers over the years in the international market. Our steel materials are widely used in power stations, bridges, ship manufacturing, offshore platforms, heavy machinery, oil and gas pipelines, tanks and so on fields.

The wear-resistant plate has high wear resistance and good impact properties. It can be laser cut, bent, welded, etc., and can be connected with other structures by welding, plug welding, screw connection and other methods. The whole process of inspection and repair It has the characteristics of time-saving and convenient. Products NM400 weathering steel are widely used in manufacturing industries such as metallurgical industry, coal, concrete, power engineering, laminated glass, mining, decorative building materials, brick kilns, etc.

The mechanical properties of 20MnV steel are as follows: tensile strength 785 MPa, yield strength 590 MPa, elongation after fracture 10%, reduction of area 40%, impact absorption energy 55 J. NM400 weathering steel, 20MnV steel has good properties, good strength, toughness and plasticity, good hardenability and machinability. After carburizing, 20MnV steel can be directly quenched without secondary quenching to improve the core structure. The weldability of 20MnV steel is good, but there is temper brittleness at 300-360 ℃ during heat treatment.

Now many manufacturers will use CNC equipment to complete the steel plate cutting processing, this processing method is also gradually increasing, but if you want to make the processing effect meet the specifications and standards, the control requirements of operation technology are also relatively high. Now there are many kinds of steel plate cutting, during the actual processing, it is necessary to select the appropriate processing method according to the cutting requirements of steel plate, so as to achieve the ideal processing effect for NM400 weathering steel.
