321/321H stainless steel coil 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.
321/321H Stainless Steel Grade:
The high sulfur content has a detrimental impact on hot workability. If hot forming is required, recommended to consider other alternative materials.
321/321H Stainless Steel Grade:
It is quite ductile and forms easily.
321/321H Stainless Steel Grade:
It can be welded by most standard processes. A post weld heat treatment is not necessary.

Hot rolling is a metalworking process. Such as steel ingots or billets are difficult to deform and process at room temperature, they are generally heated to 1100 to 1250° for rolling, this rolling process is called hot rolling. Most steel materials are rolled by hot rolling, the steel delivered in the hot-rolled state has a certain degree of corrosion resistance due to the high temperature, so it can bestored in the open air. In addition, hot rolling is that it can destroy the casting structure of the ingot, refine the grain of the steel, eliminate structural defects, make the steel structure dense, and improve the hardness of the hot rolled steel.
Cold rolling refers to a rolling process that uses the pressure of rolls to squeeze steel to change the shape of the steel at room temperature. The advantafe of cold rolling is fast forming speed, high output, the coating is not damaged, and it can be made into a variety of cross-sectional forms to meet the needs of the use conditions. In addition, cold rolling can cause large plastic deformation of the steel, thereby increasing the yield point of the steel. Which is Widely used in home appliances and other industries.
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.
