Stainless Steel 321H, marked as UNS S32109, is a stabilized austenitic grades of stainless steel developed to have superior strength at high temperatures. It has the outstanding properties of high resistance to intergranular corrosion after long exposure to high temperatures of up to 1000 0 C and thus making it to be used in thermal processing equipment, chemical plants and refineries.

Our SS 321H Tubes meet the international standards such as ASTM A213 and ASTM A269 and they are dimensionally accurate and free of any metallurgical defects. The tubes have numerous applications in the heat exchangers, superheaters, condensers and the boader tubes where high temperature and pressure resistance are needed. Since 321H stainless steel tubes have high carbon content, they have higher creep strength and hence can be used in temperature of 1000-1600F.
