F53 Material introduction

F53(UNS S32750)Its pitting corrosion index (PRE) is higher than 40. It belongs to super duplex stainless steel with excellent corrosion resistance and strength characteristics. Compared with UNS S32205, SUS 329J3L and SUS 329J4L (NAS 64), it has better local corrosion resistance, and can be used for complete chemical equipment, complete seawater desalination equipment, etc. The company can supply forgings, flanges and pipe fittings.
