Sachiya Steel International is one of the Leading Manufacturer And Exporter Of High Quality Super Duplex Steel S32750 Nipple, which has good weldability and post heat treatment of weld areas not required. Being a two – phase material (austenitic – ferritic) Super Duplex S32750 Hexagon Reducing Nipple will present a different tool wear profile from that of single – phase steels of type ASTM 304L. It is recommended that a tougher insert grade is used than when machining austenitic stainless steels, e.g. Super Duplex S32760 Hexagon Nipple, where the cutting speeds must therefore be lower than that recommended for 304L.
The maximum temperature of Super Duplex S32750 One End Threaded Nipple for long periods of service: 280 Degree C (536 Degree F); with 300 Degree C / 572 Degree F possible for short periods. Heat this Super Duplex S32760 Both End Threaded Nipple for up to 1025 Degree C – 1120 Degree C ensuring sufficient time is allowed for the center to achieve furnace temperature and hold for a time commensurate with the ruling section, followed by water quenching.
Super Duplex S32750 Concentric Swaged Nipple is readily weldable using many of the standard electric arc welding processes but oxyacetylene welding is not recommended because carbon pickup in the weld metal may occur. In addition, high resistance to crevice and stress corrosion coupled with the increased strength give Super Duplex S32760 Eccentric Swaged Nipple the advantage over the austenitic (300 series) and 22 % Cr duplex stainless steels.
