Specification Sheet: Alloy 321/321H - Sandmeyer Steel
Alloy 321H (UNS S32109) 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 1000°F (537°C). In most instances, the carbon content of the plate enables dual certification. Alloy 321 cannot be hardened by heat treatment, only by cold working.Seamless Pipe Penn StainlessHeat Treating & Annealing. Penn Stainless Products can heat treat some 400 series stainless steel seamless tube. Heat treating realizes stress as a result of hardening, depending upon the chemistry of the metal being treated.
