Product Introduction

347 Stainless Steel Plate is a niobium stabilized austenitic stainless steel plate. SS 347 Plate has excellent resistance to intergranular corrosion when exposed to the chromium carbide precipitation temperature range of 800 – 1500°F (427 – 816°C). Alloy 347 has good oxidation resistance and creep strength up to 1500°F (816°C). The corrosion resistance of annealed 347 alloy is stronger than that of 321 alloy in the annealed condition in strongly oxidizing environments.
