Alloy 254 SMO™ (6-moly) Tubing

Alloy 6MO tubing is a high-alloy austenitic stainless steel designed for maximum resistance to pitting and crevice corrosion. The high levels of chromium, molybdenum, and nitrogen make 254 SMO (6-moly) suitable for high chloride environments such as brackish water, seawater, pulp mill, bleach plants, and other high chloride process streams. Since alloy 6MO is compatible with the common austenitic stainless steels, it is often used as a replacement in critical components of larger constructions where type 316L or 317L has failed by pitting, crevice attack, or chloride stress corrosion cracking. Though alloy 6MO is substantially stronger than the common austenitic grades, it is also characterized by high ductility and impact strength.
