LORK is a special stainless steel manufacturer with 20 years of manufacturing experience.
Alloy 321H (UNS S 32109) stainless steel plate is the higher carbon (0.04 - 0.10) version of the alloy. It was developed for enhanced creep resistance and for higher strength at temperatures above 1000oF (537°C). In most instances, the carbon content of the plate enables dual certification.

Alloy 321 stainless steel plate can be easily welded and processed by standard shop fabrication practices.
The alloy is quite ductile and forms easily.
The high sulfur content of Alloy 303 also has a detrimental impact on hot workability. If hot forming is required, once again, 304 should be considered as an alternate selection.
Alloy 321 stainless steel plate can be readily welded by most standard processes. A post weld heat treatment is not necessary.
