Randhir Metal is one of the prominent exporting house and seller of Duplex Steel S31803 HEX 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 S31803 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,
