We Sachiya Steel International use the best technology for fabricating Stainless Steel 321H Pipes. Our product is available as per our client’s requirement in various shapes and, sizes.
Grade 321 is a stainless steel alloy used in high- temperature environments. The product along with forming has good welding capabilities. The product with the addition of titanium is a good choice in operating temperatures environment. Carbide precipitation during weldability is prevented due to titanium addition in the product. Pipes are available in various forms like welded and, seamless. In operating temperatures higher than 800 degrees the product was widely used. As compared to Alloy 302 or alloy 304,321H pipe has slightly less corrosion resistance in annealed conditions. The product is widely used in applications like aircraft parts. In the operating temperature environment, the product has its own merits.
