Overview: SUS630 martensitic precipitation hardening stainless steel. High strength, high stiffness, good weldability and corrosion resistance. It has been a lot of promotion of the use of the valve, shaft and chemical fiber industry and has a high strength corrosion resistance required parts. 630 stainless steel is a martensitic precipitation hardening stainless steel. Features 630 stainless steel is easy to adjust the intensity level can be adjusted by varying the heat treatment process, martensitic transformation and the aging process for forming a precipitation hardening phase is their primary means of enforcement, good attenuation performance 630 stainless steel, corrosion-fatigue and anti-drop performance strong. Applications? Offshore platforms, helicopter deck, other platforms? Food industry? Pulp and paper industry? Aerospace (turbine blades)? Mechanical parts? Nuclear waste barrel 630 stainless steel is made of copper, niobium / columbium composed of precipitation hardening, martensitic stainless steel. Feature added copper species precipitation hardening steel. For the manufacture of shafts, turbine components. Martensitic precipitation hardening of copper, niobium / columbium constructed of stainless steel, low carbon content, corrosion resistance and weldability than the average number of martensitic stainless steel, similar to the 18-8 stainless steel, heat treatment process is simple, cutting It is good, but more difficult to meet the deep cold. Microstructure: Organizing for the precipitation hardening. Use for the manufacture of high corrosion resistance, high strength parts, such as bearings class, turbine parts.
