Liquor Tank Seamless Stainless Steel Pipe , Thin Wall Stainless Steel Tube / Pipe ASTM A789 S32750

ASTM A789 specification covers seamless tube and welded tube of duplex and super duplex (UNS S32205, UNS S31803, UNS S32760, UNS S32750) stainless steel. These duplex steel tubes are more prone to precipitation of sigma phase, nitrides and carbides than corresponding austenitic steels, causing embrittlement and reduced corrosion resistance. The formation of intermetallic phases such as sigma phase occurs in the temperature range 600-1000°C and decomposition of ferrite occurs in the range 350-500°C (475°C embrittlement). The high tensile strength of duplex steel tube also implies high fatigue strength. Due to their high chromium content, duplex steels offer excellent corrosion resistance in many media.
