standard of nm450 wear-resistance cold bending performance

With the development of pipeline steel plate technology and the advancement of welded pipe forming and welding technology, the application scope of pipeline welded pipe is gradually expanding, especially in the range of large-diameter group spacing. Occupying a leading position in the field of line pipes has restricted the development of stainless steel seamless line pipes. In 2004, the output of standard of NM450 wear-resistance seamless line pipes was about 400,000 tons, with steel grades including X42-70, and varieties of onshore line pipes and subsea line pipes.The company has always adhered to the principle of "genuine goods at low prices", put an end to the sale of fake and shoddy standard of NM450 wear-resistance 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 standard of NM450 wear-resistance 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.S355NC steel offers excellent bending, flanging, cold-bordering and folding standard of NM450 wear-resistance properties in both longitudinal and transverse direction. The bending radii specified below should be observed as minimum values.The allowable temperature of standard of NM450 wear-resistance, boiler steel is mainly determined by strength condition. Different steels have different mechanical properties and high temperature properties. Even for the same kind of steel, the tensile strength, yield strength and rupture strength vary greatly with the working temperature, and decrease with the increase of working temperature. In order to ensure the safety of standard of NM450 wear-resistance work, the actual stress of standard of NM450 wear-resistance under the working temperature should be less than the allowable stress determined by the tensile strength, yield limit and permanent strength of standard of NM450 wear-resistance under the temperature.The company conducts periodic and targeted training and guidance for after-sales service personnel. As the saying goes, "no one is perfect, no gold is red", to help after-sales service personnel improve service skills and correct service attitude. Carry out relevant technical training for after-sales service personnel, so that after-sales service practitioners have professional product knowledge.
