ASTM A815 UNS S32750 Reducer
ASTM A815 UNS S32750 Reducer
ASTM A815: Applicable to forged austenitic and duplex stainless steel pipe fittings (butt welding, socket welding, threaded connection), including elbows, tees, reducers, etc. It has both austenitic and ferritic structures, and its strength is twice that of 304 stainless steel. It has excellent resistance to chloride stress corrosion (SCC), pitting corrosion and crevice corrosion.
With ultra-high strength, it can reduce pipe wall thickness and system weight. Its excellent corrosion resistance can
Resistant to seawater, chlorides (such as oilfield brine), H₂S/CO₂ acidic environments, which is better than conventional duplex steel (such as 2205/S31803). It is stable in high temperature (≤300°C) chlorine-containing environments and is suitable for offshore platforms and chemical pipelines.
