The most significant strength of Stainless Steel 321H Pipes is their capacity to withstand conditions of extended exposure to high temperature and stress without degrading the inner strength of the material. The increased carbon percentage in SS 321H compared to SS 321 increases the strength and stress rupture capacity of the material and makes it suitable for high-pressure conditions. It has resistance against oxidation at 1500°F (816°C) and superior resistance against carburizing atmosphere and hence is suitable for application in furnace and exhaust systems, refineries, and chemical processing industries.
