630 Stainless Steel Grade 630 stainless steels are martensitic stainless steels that are precipitation hardened to achieve excellent mechanical properties. These steel achieve high strength and hardness following heat treatment. The heat and corrosion resistance of grade 630 are similar to that of grade 304 steels. This grades is also commonly referred to as grade 17-4PH. One of the key benefits of this grade is that it is available in solution treated conditions, at which they can be easily machined and age-hardened to attain high strength. The age treatment of grade 630 is carried out at low temperatures, to avoid significant distortion. Therefore, this grade is used for applications such as the manufacture of long shafts that do not require re-straightening after heat treatment. Chemical composition： Fe, <0.07% C, 15-17.5% Cr, 3.0-5.0% Ni, <1.0% Mn, <1% Si, <0.040% P, <0.03% S, 3.0-5.0% Cu, 0.15-0.45% Nb+Ta
It is mainly divided into two types: cold rolled and hot rolled stainless Steel Coil. Stainless steel cold rolled coil always comes in two surface finishes, namely 2B and BA finish. For hot rolled stainless coils, it is usually No.1 finish. Stainless steel coil are inventoried in 200 series, 300 series, 400 series. Different processing processes allow us to finish different complex requirements from customers. Cutting SS coil to specified width, processing the surface, protecting the coil finish by different PVC, PE film.
