Stainless Steel 321H Sheets & Plates are austenitic stainless steel products that contain a higher carbon content compared to the standard 321 grade. The addition of titanium in this alloy helps to stabilize the structure and prevent carbide precipitation, which can occur during welding or exposure to high temperatures. This enhanced version, 321H, is designed specifically for applications requiring higher strength and better performance at elevated temperatures, typically up to 900°C (1652°F). This makes it an ideal material for industries where extreme conditions are common.
