The 347 stainless steel grade is a stabilized alloy, due to its columbium + tantalum component within. Ideal for long-term work life in high temperatures (800-1500ºF), 347 Stainless Steel is also resistant to intergranular corrosion in the chromium carbide precipitation range. High creep and stress rupture properties are part of their superior mechanical properties.
