Stainless Steel 321H Sheet is made up of an austenitic stainless steel with high carbon content for added toughness. There are different forms of the sheets such as the SS 321H Coils foils and strips that are used in different applications. Suryadeep Industry is a leading manufacturer and supplier of the 321H Stainless Steel Hot Rolled Plates and products. The plates could be cold rolled or hot rolled. The material is the basic 18/8 stainless steel with added titanium or niobium for stabilization. The composition of the Stainless Steel 321H Coils includes manganese, carbon, phosphorus and sulfur with chromium and nickel. The material has 205MPa minimum yield strength and 515MPa minimum tensile strength. The Brinell hardness score of the material is 215. The Stainless Steel 321H Slatting Coils are used in applications with high temperature demands.
The material can operate up to 900 degrees Celsius temperatures. It is heated above 425 degrees Celsius to get rid of sensitization to carbide precipitation. The 321H Stainless Steel 2B Plate is a type of finishes available in the material. There are different finishes to the sheets and plates such as perforated and checkered. These are required by special applications. The 321H Stainless Steel Plates can be seen in construction, automobile, boiler, heat exchanger, food processing and petrochemical industrial applications as well. The corrosion resistance of the 321H Stainless Steel Polished Plates makes them a good choice for general corrosive applications and pressure vessel applications. The different types of applications can use the SS 321H Cold Rolled Plates because of the forming, machining and welding abilities as well. The 321H SS Coils last longer because of the extended lifespan due to the stabilization. Please contact us for more information on the 321H SS Strips, coils, foils and plates.
