Sachiya Steel International is one of the Leading Manufacturer And Exporter Of High Quality Duplex Steel S31803 Nipple, which should be allowed to cool to below 300 Degree F between welding passes. Whenever hot forming is done, Duplex Steel S31803 Hexagon Reducing Nipple should be followed by a full solution anneal at 1900 Degree F minimum and rapid quench to restore phase balance, toughness, and corrosion resistance. Stress relieving is not required or recommended; however, if it must be performed, Duplex S32205 Hexagon Nipple should receive a full solution anneal at 1900 Degree F minimum, followed by rapid cooling or water quenching.

Stress relief treatments at any lower temperature for Duplex S31803 One End Threaded Nipple carry the risk of precipitation of detrimental intermetallic or non – metallic phases. As with all stainless steels, such as for Duplex Steel S32205 Both End Threaded Nipple, good joint preparation, alignment, and cleaning are essential for good quality welds.

Duplex Steel S31803 Nipple

Pre – heating of Duplex Steel S31803 Concentric Swaged Nipple is not necessary or desirable unless it is used only to prevent condensation, or in certain unusual cases involving connecting very light sections to very heavy sections. Hot cracking is not impossible but is much less likely to occur with Duplex Steel S32205 Eccentric Swaged Nipple than with austenitic materials. Weld zones in Duplex S32205 Nipple should be clean before welding and well shielded by inert gas, typically dry argon, during welding.
