Welded 6 Moly Pipe

6 Moly grades have superior resistance to many chemicals thanks to their high levels of chromium, molybdenum, and nitrogen. Furthermore, this makes them excellent for use in high chloride environments like brackish water, seawater, and pulp mill beach plants. 6 Moly grades also demonstrate a cost-efficient substitute for nickel-based alloys and titanium.

6 Moly grades benefit from molybdenum’s high melting point. Molybdenum is used as an alloying agent in certain grades of steel, Permalloys and Stellites (a series of alloys which contain varying proportions of Cr, Co, W and Mo, are very hard and are used in cutting tools and to protect surfaces subject to heavy wear).

6 Moly Grades*

254 SMO

Alloy 254 SMO (UNS S31254) is a molybdenum and nitrogen alloyed super austenitic stainless steel. This grade posesses low carbon content. Super-austenitic stainless steels generally show excellent resistance to chloride pitting and crevice corrosion because of their high molybdenum content (>6%) and nitrogen additions.
