The company produces seamless steel pipes such as GB, ASTM, etc. all year round, including low and medium pressure boiler steel pipes, high pressure boiler steel pipes, NM400 material meaning seamless steel pipes for ships and petroleum cracking NM400 material meaning steel pipes, Seamless steel pipe, oil sleeve steel pipe, pipeline steel pipe, hollow sucker rod, common fluid steel pipe, structural pipe, kauden steel pipe, seawater corrosion-resistant titanium pipe and imported alloy steel pipe are used for high-pressure fertilizer equipment. The products are widely used in petroleum, chemical, electric, boiler, ship, machinery and other industries, and have been sold all over the country. Many NM400 material meaning products have been exported to the Middle East, India, Southeast Asia and Europe and America.
As a bulk commodity, the rise and fall of NM400 material meaning, steel pipe prices are related to many downstream industries, such as construction industry, railway, highway, urban public transport and other infrastructure construction, industry and real estate. The price of NM400 material meaning, steel pipe rises and falls every day, and is guided by the quotation market in various places. However, in fact, the procurement of steel pipes is more complicated than this, and the market guide price can only be used as a reference.
NM400 material meaning, Chinese grade 45 steel belongs to high quality carbon structural steel. The application of NM400 material meaning, Chinese grade 45 steel depends on its various properties. NM400 material meaning, Chinese grade 45 steel has certain toughness and plasticity, high strength and good machinability. Good comprehensive mechanical properties of Chinese grade 45 steel can be obtained by quenching and tempering treatment. Chinese grade 45 steel is suitable for manufacturing high strength moving parts, such as air compressor, piston of pump, impeller of steam turbine, rolling shaft, connecting rod, worm, rack, gear and pin in heavy and general machinery.
Both steelmaking and ironmaking are carried out by oxidation-reduction reaction, but there are great differences between them in reaction objects: ironmaking is to reduce iron, while NM400 material meaning steelmaking is to remove excessive carbon and other impurities in pig iron, so there are relations and differences between them in actual operation. There are three main methods of NM400 material meaning steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.
NM400 material meaning, 09CuPCrNi-A weather resistant steel is origined in China. Its equivalent grades are JIS SPA-H, BS WR50A, Corten steel, etc. The Cu, P, Cr, Ni are important elements that gave 09CuPCrNi-A weather resistant steel its weathering ability. The Cu content of 09CuPCrNi-A steel is 0.25–0.50, P content is 0.060-0.12, Cr content is 0.30-1.25, Ni content is 0.12-0.65. For 09CuPCrNi-A steel coil ≤ 4mm, the min. yield strength is 310Mpa, min. tensile strength 440Mpa. For 09CuPCrNi-A steel sheets >4mm, the min. yield strength is 345Mpa, min. tensile strength 480Mpa.
