UNS S32750 /1.4410 /2507 Super DuplexStainless Steel Pipe

Containing high level ofchromium, molybdenum and nitrogen, UNS S32750, 1.4410 or 2507 super duplexstainless steel pipe has superior corrosion proof performance, for instance, excellentresistance to pitting and crevice corrosion in seawater and otherchloride-containing circumstances. In addition, it also comes withcritical pitting temperature over 50℃.As compared to the austenitic steels, our product features lower thermal expansivity as well as higher thermal conductivity due toits duplex microstructure. Moreover, its working temperature is up to 300℃.Last but not the least, our super duplex UNS S32750 has been approved bypressure vessel applications.
