321 stainless steel plate is a ferritic stainless steel plate with stable titanium and carbon content. It has good corrosion resistance and high-temperature strength. It is usually used in high-temperature corrosion-resistant environments, such as heat treatment equipment, chemical equipment, etc.

321H stainless steel plate is a high-carbon version of 321 stainless steel plate. It has higher high temperature resistance and is suitable for use in higher temperature environments. It is often used in high-temperature stoves, furnace tubes and other fields.
