Stainless Steel 321H is an austenitic stainless steel stabilized by titanium and noted for its excellent resistance to high temperatures and corrosive environments. It finds applications for parts that go through intermittent heating up to 1500°F and continuous use up to 1650°F. The superior corrosion resistance of Stainless Steel 321H Sheets and Plates is due to the formation of a uniform, compact passive layer on the surface that protects it from various corrosive elements.
Sankalp Alloys Overseas produces Stainless Steel 321H Sheets and Plates with the minimum titanium addition five times the carbon content, unlike Type 304, but having enhanced properties. This means that it is stabilized, providing better resistance to carbide precipitation at higher temperatures, mainly due to welding or other exposure conditions at higher temperatures—this makes this grade of valuable steel in many critical applications. These sheets and plates have applications in paper industries, shipbuilding, aerospace military, and other allied fields. The high-strength performance of the alloy in the sectors related to gas processing and power generation further testifies to the versatility in use. Sankalp Alloys Overseas assures customers' highest satisfaction by providing all types of material testing services.
These Stainless Steel 321H Sheets and Plates have good mechanical properties for high-temperature service due to their excellent creep and great stress rupture properties. Also, they maintain their temperability at low temperatures, contributing to reliable performance in an extensive temperature range. It is owing to these properties that Stainless Steel 321H becomes an important steel alloy for industrial applications where dependable performance alloys are required.
