904L stainless steel plate is a kind of pipe fittings, which carries out a circle of argon arc welding between the stainless steel pipe and the pipe fittings along the butt joint, usually welding. According to the edge welding part of 904L stainless steel plate, there are three types of 904L stainless steel plate: groove extension, step edge extension and no extension. The socket welding specification is generally DN15-DN100.The Steel GB/T700 Q235B Plate plate products have passed the EU CE certification, and have been recognized by China, France, the United States, the United Kingdom, Germany, Italy, Japan, South Korea and other eight classification societies for high-strength ship plates. The steel strand products have passed the United States (PTI) certification. The Steel GB/T700 Q235B Plate products enjoy a high reputation in the domestic and foreign markets. The products are applied to national key projects and sold to 37 countries and regions such as EU, Middle East, Southeast Asia and America.Quenching Improve the hardness of Steel GB/T700 Q235B Plate steel, Annealing is refine the grain size, homogenization, reduce hardness, improve the plasticity and eliminate interna stress. Normalizing refine grain , improve the impact toughness of Steel GB/T700 Q235B Plate steel and comprehensive mechanical properties.The composition characteristics of low alloy high strength steel are low carbon ≤0.20%, low alloy, and total alloying elements is less than 3%. The low carbon content is to meet the process performance requirements of Steel GB/T700 Q235B Plate, low alloy high strength steel for engineering structural parts such as plasticity, toughness, weldability and cold deformation; adding a small amount of alloying elements (mainly Mn) to achieve the purpose of improving mechanical properties. Mn not only has a significant strengthening effect on ferrite, it can also reduce the cold brittle temperature of steel, increase the amount of pearlite in the steel, and further improve the strength.Adhere to the spirit of quality first and user foremost, carry out maintenance and other work according to the requirements of the buyer's contract, and ensure that the engineering project and product after-sales play their application effectiveness. Our company guarantees to carry out self inspection and self supervision according to the quality management policy proposed by our company, and deliver a high-grade, perfect and excellent system engineering to users.
