Analysis of nm400 steel grade social inventory

The cold rolling precision bright pipe system produced by our factory has smooth appearance, uniform wall thickness, no oxide layer and high precision. The inner hole of NM400 steel grade steel pipe can be divided into round, spline and plum blossom, which is widely used in automobile, motorcycle, electric power, petrochemical, ship, aerospace, bearing, pneumatic components, oil cylinder, boiler equipment, medical equipment, fitness equipment and other industries. Materials can be divided into: 10#, 20#, 35#, 45#, 40Cr, 16Mn, etc. According to the needs of users, we can make all kinds of national standard non-standard precision pipes. Special NM400 steel grade materials and specifications can be ordered in advance.

ASTM A285 steel can be made into a variety of steel product forms, such as steel plates, NM400 steel grade steel coils, and steel pipes. It has good welding ability and can be used for fusion welding required by pressure vessel equipment. Its maximum thickness is limited to NM400 steel grade 50mm to ensure its mechanical properties.

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 steel grade, 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.

Weathering steel plates have an excellent corrosive resisting property like resistance to crevice and pitting corrosion, resistance to corrosion and oxidation. This plate also has resistance to chloride corrosion cracking and stress corrosion. These plate are not affected very easily by acids and environmental rust and works in the sulfide atmosphere. NM400 steel grade, Weather resistant steel plates have excellent workability, formability, easy to install, easy to fabricated, machinability, durability, reliability.
