UNS S31254 Stainless Steel Pipe Spool
UNS S31254 stainless steel pipe spool is an super austenitic stainless steel pipe and flange welding product.
Due to the high molybdenum content, it has extremely high resistance to pitting corrosion and crevice corrosion.
It is a substitute product for nickel based alloys and titanium pipe spools.
What’s more, it has better high temperature resistance and corrosion resistance, which is irreplaceable for 304 stainless steel pipe spool.
