Pressure Vessel Quality SM400C carbon steel material Plate

Q345E steel plate is a low-alloy high-strength steel plate with good low-temperature impact performance. The steel grade is composed of three parts: Q (Qufu in Chinese spelling) representing yield strength, yield strength value, and quality grade symbol. , Among them: Q represents the yield strength; 345 represents the yield strength value, unit MPa; E represents the grade (passed -40 degrees impact test).SM400C carbon steel material,The company has always adhered to the principle of "genuine goods at low prices", put an end to the sale of fake and shoddy 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 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.SM400C carbon steel materialwe also provide the welding service for customers, and our welding method, hand arc welding, submerged arc welding and tungsten argon arc welding, melting polar gas shielded welding and so on. And we have lots of successful welding project, such as longitudinal submerged arc welding pipe, welding cross colume, prestressed truss and welding box colume.SM400C carbon steel material,Composition characteristics of low alloy structural steel, SM400C carbon steel material: (1) Low carbon: the carbon content of low alloy structural steel is less than 0.20% due to the high requirements of toughness, weldability and cold formability. (2) The alloy elements such as manganese are added. (3) The addition of Nb, Ti or V and other auxiliary elements: a small amount of Nb, Ti or V forms fine carbides or carbonitrides in the steel, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of low alloy structural steel. In addition, adding a small amount of copper (≤ 0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. The addition of a small amount of rare earth elements can remove sulfur and gas, purify the steel, and improve the toughness and process performance of low alloy structural steel.Compared with other fast-moving consumer goods, steel consumption is obviously different, with a wide range of use and a long service life. Therefore, the quality and service of steel materials are particularly important. Service is always one of our top concerns, especially after-sales service. We have mature after-sales service team, and can help you solve problems professionally during application of the steel materials.SM400C carbon steel material
