As a professional Chinese supplier of JIS G3125 SPA-C steel plates, JIS G3125 SPA-C weathering steel plates are made of carbon steel and copper, nickel, phosphorus and other chemical elements. The content of these chemical elements, only a few percent. Because different alloying elements, weather resisting steel has better mechanical properties, as well as greater corrosion resistance. Thus, SPA-C steel used for marine containers, container, bridges, and train tracks.
JIS G3125 SPA-C weathering steel properties: The corrosion retarding effect of the protective layer is produced by the particular distribution and concentration of alloying elements in it. As a result, the layer protecting the surface develops and regenerates continuously when subjected to the influence of the weather. In other words, the steel rusts to form the protective coating.
JIS G3125 SPA-C equivalents: ASTM A242 (COR-TEN A), ASTM A588 (COR-TEN B), S355J2WP+N, S355J2W+N, S355JOWP, S355JOW, S355J2W, 1.8946, 1.8965
