Sachiya Steel International is one of the Leading Manufacturer And Exporter Of High Quality Stainless Steel 317 Nipple, which has excellent resistance to a wide variety of corrosive media. SS 317 Hexagon Reducing Nipple has reasonable resistance to salt water in cold southern waters but is unlikely to be successful in warmer tropical waters. Overall the corrosion resistance of Stainless Steel 317 Hexagon Nipple is approximately the same as or slightly below that of Grade 304. Performance of SS 317 One End Threaded Nipple is best with a smooth surface finish, in the hardened and tempered condition.
Heat this Stainless Steel 317 Both End Threaded Nipple up to 980 Degree C – 1035 Degree C, followed by quenching in oil or air, where oil quenching is necessary for heavy sections. Temper this Stainless Steel 317 Concentric Swaged Nipple at 150 Degree C – 370 Degree C to obtain a wide variety of hardness values and mechanical properties as indicated in the accompanying table.
Stainless Steel 317 Eccentric Swaged Nipple resists scaling in intermittent service to 925 Degree C and in continuous service to 870 Degree C, but is generally not recommended for use in temperatures above the relevant tempering temperature, because of reduction in mechanical properties. Welding of these 317 Stainless Steel Nipple is difficult due to the risk of cracking, where a pre – heat of 200 Degree C – 300 Degree C is recommended prior to welding.
