Butt Weld Pipe Fittings ASTM A403 WP317-S Stainless Steel Concentric Reducer ANSI B16.9
Comprised of higher contents of chromium, nickel and molybdenum, fittings made from stainless steel 317 tend to be more corrosion resistant as compared to SS316. This is also due to the high percentage of iron in the chemistry of Stainless Steel 317 Pipe Fittings. The combination of iron with the alloying of chromium-nickel-molybdenum content yields a strong and hard alloy. We manufacture stainless steel concentric and eccentric reducers for more than 30 years which have high quality and we also supply other buttweld stainless steel fittings, like 45/90/180 degree elbows, reducing tees, equal tees, end caps and so on.
