GNEE is a professional exporter of super duplex steel UNS S32750 pipes and tubes manufacturers and suppliers and can provide different shapes and sizes according to customer requirements, and can also easily adapt to any size.
The continuous use temperature range of S32750 duplex stainless steel pipe is -50 degree to 250 degree . The lower limit depends on the brittle transition temperature of steel, and the upper limit is limited by the brittleness of 475 degree . Therefore, attention should be paid to temperature control when using it.
