| Description: CLI SIRIUS S12 grade is an austenitic stainless steel containing 20% Cr, 1.8 % Si and 12% Ni. The low nickel content combined with high chromium and high silicon contents provide good resistance to high temperature oxidation, even in sulphur containing gases The structure stability of the grade is enhanced compared to other more alloyed heat resistant steels. The alloy is designed to resist in oxidizing atmospheres up to 1000°C (1832°F). In cyclic conditions, a maximum temperature of 950°C (1742°F) should be considered. The alloy performs much better than 304 H and 304 N grades. Information provided by manufacturer. |
