LORK is a special stainless steel manufacturer with 20 years of manufacturing experience.
321 (UNS S32100) is a titanium stabilized austenitic stainless steel with good general corrosion resistance. It has excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 800 - 1500°F (427 - 816°C). The alloy resists oxidation to 1500°F (816°C) and has higher creep and stress rupture properties than alloys 304 and 304L. It also possesses good low temperature toughness.
321H (UNS S 32109) 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.
321 cannot be hardened by heat treatment, only by cold working. It can be easily welded and processed by standard shop fabrication practices.
321 stainless steel plate is also advantageous for high temperature service because of its good mechanical properties. 321 stainless steel plate offers higher creep and stress rupture properties than 304 and, particularly, 304L, which might also be considered for exposures where sensitization and intergranular corrosion are concerns.
