PT. Cahaya Bina Baja is a distributor of Duplex Steel UNS S32205 / UNS S31803 Pipe Flanges, which has better resistance to sea water then Stainless Steel 316. Concerning taciturn workability in these Duplex Steel UNS S32205 Flanges, and so care is being needed as resistant pressure is soaring and elongation is squat when compared by means of Alloy 304. Duplex Steel UNS S31803 Flanges is often used in Marine Applications, Mining Industry, Oil and Gas Extraction and Processing, etc. The best suitable heat treatment for Duplex Steel UNS S32205 Slip On Raised Flanges is solution conduct (annealing), in the range of 1020°C - 1100°C, trailed by rapid cooling. Duplex Steel UNS S31803 Blind Flanges has shown good formability in a variety of fabrications, and gives better guaranteed corrosion resistance. Our Duplex Steel UNS S32205 Weld Neck Flanges are extremely corrosion resistant, and have high resistance to inter-granular corrosion.

Low heat inputs should be used for welding of these Duplex Steel UNS S31803 Socket Weld Flanges, where it further has resistance to chloride pitting and crevice corrosion. Due to its higher corrosion resistance, our Duplex Steel UNS S32205 Threaded Flanges has better fatigue strength in corrosive environments than that of other austenitic stainless steel specifications. These Duplex Steel UNS S31803 Lap Joint Flanges is being used for upstream manufacture of soaring chloride oil and gas fluids, water conduct dispensation modules, and paper and pulp dispensation.
