SSC-6MO (UNS N08367) is a superaustenitic 6% molybdenum alloy that exhibits far greater resistance to chloride pitting, crevice corrosion and stress-corrosion cracking than the standard 300 series and standard duplex stainless steels. It also serves as a cost-effective substitute for more expensive nickel-base alloys in applications where excellent corrosion resistance, strength, formability and weldability are essential. Designated as (UNS N08367), SSC-6MO competes directly with Alloy AL6XN®.

The high nickel (24%) and molybdenum (6.5%) contents contribute to the alloys chloride stress-corrosion cracking resistance, while the molybdenum content also provides resistance to chloride pitting. The high levels of chromium (21%), molybdenum and nitrogen (0.22%) all serve to produce exceptional corrosion resistance.

Due to its high nitrogen content, SSC-6MO has higher tensile strength than the common austenitic stainless steels. The ASME design-stress allowances for SSC-6MO are up to 75% higher than 316L and more than two times those of the copper-nickel alloys.

The toughness and ductility of SSC-6MO provide for ease of fabrication. SSC-6MO welds and forms much more readily than any super duplex or high alloy ferritic stainless steel with comparable corrosion resistance.
