347 Stainless Steel - Where Resistance Meets Reliability.

Discover the High-Temperature Capabilities of 347 Stainless Steel.

This grade is commonly utilized in the 800-1500°F temperature range, where it is stabilized against chromium carbide precipitation by adding niobium, which causes niobium carbides to precipitate.

After exposure to the 800-1500°F temperature range, the Type 347 stainless steel round bar has intergranular solid corrosion resistance. This grade resists oxidation up to 1500°F and has higher creep and stress rupture capabilities than 304/304L. In the annealed state, the 347 round bar is also nonmagnetic and has good low-temperature toughness.
