Hot Sales Threaded Stainless Steel Flange

　　Hebei Shengtian Pipe fitting Group Co.,Ltd is a factory producing steel flanges. The most popular material grades are made from carbon steel. We sell Hot Sales Threaded Stainless Steel Flange and flanged fittings also. After forging, the metal can improve its structure and mechanical properties. After the deformation of the forging method of hot forging deformation of the metal deformation and recrystallization, the original coarse dendrites and columnar grains into smaller grain size, uniform size of the equiaxed recrystallization of the organization so that the original ingot of segregation, Loose, porosity, slag and other compaction and welding, the organization becomes more closely, and improve the plasticity of metal and mechanical properties.
