321 and 321H stainless steel sheets are basic austenitic materials. These grades are stabilized by the addition of titanium. These grades are typically used for applications at temperatures up to 1,650°F. These grades combine high strength, resistance to scaling and phase stabilization, and resistance to subsequent water corrosion. 304L plate is more readily available in most product forms, so if resistance to intergranular corrosion after welding is only required, 321 or 321H is generally preferred. however, 304L has lower thermal strength than 321 and 321H plate, so if resistance to more than 932°F is required operating environment, 304L may not be the best choice.
