杉山金属 List of Products and Services

This is a lean duplex stainless steel developed by Nippon Steel & Sumitomo Metal Corporation, leading the world in innovation. With a composition of 21% Cr and 2% Ni, it forms a fine microstructure that combines ferritic structure, represented by SUS430, and austenitic structure, represented by SUS304, resulting in a strength that is 2.5 times that of ordinary steel and about twice that of SUS304. This allows for significant weight reduction. Furthermore, it has excellent corrosion resistance and is less prone to stress corrosion cracking in chlorine environments after processing, demonstrating reliability in coastal conditions. Initially named NSSSC2120, it obtained JIS certification on September 24 last year and is now designated as SUS821L1. Currently, it is primarily used for solar power generation frames and mounting hardware, but an expansion of applications in various fields is expected in the future.

The high corrosion-resistant, low-chromium high-purity ferritic stainless steel "NSSC FW1" has won the 2010 Nikkei Excellent Products and Services Award, as well as the Grand Prize of the Nikkei Industrial Newspaper Award. It is a stainless steel that excels in "workability," "corrosion resistance," "reduced alloying," and "design." Thanks to Sn addition technology, it possesses high corrosion resistance and, like other high-purity ferritic steels, has good weldability, as well as excellent corrosion resistance and workability. 【Features】 ■ Despite having 14% Cr, it exhibits corrosion resistance superior to that of 18% Cr steels due to Sn addition technology. ■ In salt spray tests under the same conditions, the degree of rusting is less than that of SUS430LX. ■ Thorough reduction of alloying (no Ni or Mo added, reduced Cr) avoids the impact of raw material prices. ■ The surface properties (resistance to ridging) after processing are high. *For more details, please refer to the catalog or feel free to contact us.
