321/321H stainless steel plate is a austenitic stainless steel gtades with titanium. It is quite ductile and forms easily in cold forming process. If hot forming is required, other alternative materials is recommended to consider. 321/321H stainless steel can be polished to some degree but is not recommended for decorative applications. It is commonly used in heat exchangers, even the aerospace industry.

What Are The Classes Of Stainless Steel?
Answer:
Classes of stainless steel are organized by their crystalline structure, mainly divided into martensitic, ferritic, austenitic, duplex, and precipitation-hardening. Austenitic is the most common, 321/321H is one of the austenitic stainless steel.
What Is The Difference Between 321 And 321H?
Answer:
321H is the higher carbon version of the 321 stainless steel. The grade contains between 0.04% and 0.10% carbon. It was developed for enhanced creep resistance and for higher strength at temperatures above 1000°F.
What Does H Grades Mean?
Answer:
H grades can be used as standard grades as long as their carbon contents are 0.08% max. These grades are commonly used for applications that expose them to extreme temperature environments.
