Stainless Steel 321H Rectangular Bars are mainly made up of iron, with 17–19% chromium, 9–13% nickel, and trace amounts of titanium and carbon. The inclusion of titanium helps stabilize the steel, preventing carbide precipitation and boosting resistance to intergranular corrosion at high temperatures. In terms of mechanical properties, 321H bars exhibit excellent tensile strength, hardness, toughness, and ductility. They retain their mechanical integrity even under thermal stress, making them perfect for high-temperature settings. This unique blend of composition and performance ensures long-lasting reliability in demanding industrial applications, such as chemical and power generation equipment.
