Material Notes:
Description: CLI SIRIUS 314 grade is a fully austenitic stainless steel containing 25% Cr, 20% Ni and 1.8% Si. The alloy is designed for high temperature corrosion resistance applications even in severe conditions. Carbon additions are optimized in order to increase creep properties and mechanical properties. The alloy is well designed for applications up to 1150°C (2102°F) in oxidizing atmospheres, or up to 1050°C (2012°F) in reducing atmospheres. Sulphur, carbon or nitrogen pick up reduce the behavior of the steel. The alloy performs better than Sirius 310 or Sirius 253 grades in most of the applications.Information provided by manufacturer.
