stainless steel 321h sheet

Stainless steel 321H is a variant of the popular stainless steel alloy 321. It offers enhanced levels of resistance to intergranular corrosion and possesses higher strength at high temperatures than 321-grade stainless steel. Its composition includes iron, chromium (18-20%), nickel (9-12%), carbon (.04-.10%), manganese (2-3%), silicon (1%) and titanium (5 times the carbon content).

Stainless steel 321H sheet is a popular grade of stainless steel due to its outstanding corrosion resistance, enhanced creep strength, and excellent workout ability. This type of stainless steel is widely used in the oil & gas industry for heat exchangers, valves & flanges; in the aerospace industry for structural components and fasteners; and in power plants for superheater tubing and steam turbines. It also works as an insulated barrier layer in high-temperature applications such as automotive exhaust systems.
