The nominal composition (wt. %) of this classification is 22.5 Cr, 8.5 Ni, 3 Mo, 0.15 N. Primarily to weld duplex stainless steels which contain approximately 22 percent chromium
Used primarily to weld duplex stainless steels which contain approximately 25 percent of chromium. Weld
metal deposited has a “duplex” microstructure consisting of an austenite-ferrite matrix.
Superduplex filler metal matching the proprietary
Zeron® 100 alloy. The presence of
Cu+W in this alloy provides superior resistance
to sulphuric and hydrochloric acids
when compared to similar alloys without
these additions.
