Stainless Steel 321/321H Sheets and Plates

Stainless Steel 321/321H is a titanium-stabilized stainless steel that offers excellent mechanical properties. These plates and sheets provide outstanding corrosion resistance and resistance to intergranular corrosion when exposed to temperatures within the chromium carbide range. They also exhibit higher creep and stress rupture properties compared to other alloys. Additionally, they have good low-temperature toughness and superior strength. Stainless Steel 321H plates are particularly suitable for use in diluted organic acids at medium temperatures. They offer features such as high tensile strength, durability, and precise design.

Alloy 321 (UNS S32100) is an austenitic stainless steel plate that is titanium-stabilized and offers good general corrosion resistance. It demonstrates excellent resistance to intergranular corrosion after exposure to temperatures in the range of 800 - 1500°F (427 - 816°C) where chromium carbide precipitation can occur. The alloy also resists oxidation up to 1500°F (816°C) and possesses higher creep and stress rupture properties compared to alloys 304 and 304L. It also exhibits good low-temperature toughness.

Allianz Steel Group offers stainless steel plates of Alloy 321H, which is the higher carbon (0.04 - 0.10) version of the alloy. This variation was developed to provide enhanced creep resistance and higher strength at temperatures above 1000°F (537°C). The carbon content enables dual certification in most cases.

Alloy 321 stainless steel plates cannot be hardened by heat treatment but can be cold worked. They can be easily welded and processed using standard shop fabrication practices.

Allianz Steel Group, an ISO 9001:2008 certified company, is a leading stockholder, supplier, and exporter of ASTM A240 321 Stainless Steel Plate. The 321 Stainless Steel Plates they offer can be customized to meet specific requirements and are supplied with a complete set of mill test reports. Custom lengths and widths up to 2000mm are available. Allianz Steel Group specializes in exports and can source hard-to-find grades and non-standard sizes to fulfill customer needs. Their stock of ASTM A240 321 Stainless Steel Plate includes thicknesses ranging from 6mm up to 80mm, with widths of 1250mm, 1500mm, and 2000mm.
