Who makes cutting of nm400 plate steel plates

The company specializes in the research and development, production and sales of cutting of NM400 plate seamless pipes, longitudinally welded pipes, large-diameter welded pipes, API 5L welded pipes, spiral welded pipes, and large-diameter thick-walled straight seam steel pipes. The company has cutting of NM400 plate five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,cutting of NM400 plate rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.

According to the guarantee conditions of delivery, China and some countries divide the ordinary carbon steel into three categories: Class A steel, which only guarantees the mechanical properties, not the chemical compositions； Class B steel, which only guarantees the chemical compositions, not the mechanical properties; special steel (Class C steel), which not only guarantees the chemical compositions, but also the mechanical properties. Class C steel cutting of NM400 plate is often used to manufacture important structural parts. Density of ordinary carbon steel: 7.85 g / cm3.

Advantages of cutting of NM400 plate, stainless steel: 1. Chemical properties: the chemical and electrochemical corrosion resistance of stainless steel is the best in steel, second only to titanium alloy. 2. Physical properties: stainless steel has good heat resistance, high temperature resistance, low temperature resistance and even ultra-low temperature resistance. Stainless steel can work safely at - 270℃ - 400℃ for a long time. No matter at high or low temperature, no harmful substances will be precipitated, and the stainless steel material properties are quite stable.

cutting of NM400 plate, The hardened wear-resistant plate is quenched and hardened as a whole, and the martensite in the metallographic structure improves the overall hardness, and the micro hardness and macro hardness are basically the same. Cemented carbide and T10, even if the macroscopic hardness of T12 steel and cemented carbide after quenching is basically the same, the wear resistance of cemented carbide is much higher than that of T12 steel, because there are a large number of carbides in cemented carbide .

cutting of NM400 plate, No. 20 steel belongs to high-quality carbon steel.No. 20 steel means steel with an average carbon content of 0.20%;The thermal conductivity of No. 20 steel at 315℃ is 48 W/m℃;No. 20 steel is generally not quenched, the general treatment method is carburizing or normalizing;The yield strength of No. 20 steel is not less than 250MPa;The tensile strength of No. 20 steel is not less than 420MPa;Elongation of No. 20 steel is not less than 25%;The reduction of area is not less than 55%;The density of cutting of NM400 plate and No. 20 steel is 7.85kg/cm3

We have a professional production team and high-quality production equipment, and we also have a great cutting of NM400 plate advantage in price, with its own factory, large-scale production to reduce the price. Strictly control each production line to ensure the cutting of NM400 plate production of high-quality steel plates, steel pipes and other products that meet customer requirements.

From the order to the delivery, there are three quality inspections to ensure that the qualified rate of finished products is more than 100%. We promise that every order will be tracked in a timely manner to ensure that customers can receive goods safely and constantly listen to their opinions and suggestions, reflect on our own problems, and let customers feel at ease. We have a large warehouse in Shanghai and Tianjin, which can provide customers with sufficient sources of supply.
