Stainless Steel 904L Nipple Manufactures In India
Sachiya Steel International is one of the well-known manufacturing units for Stainless Steel 904L Nipple, which is quite ductile and forms easily. The addition of molybdenum and nitrogen in Stainless Steel 904L Hexagon Reducing Nipple implies more powerful processing equipment may be necessary when compared with the standard 304 / 304L grades. Segregation is less evident in Stainless Steel 904L Hexagon Nipple, and this material is normally welded using a filler metal of the same composition as the base metal and can even be welded without filler metal.
The cold work hardening rate of Stainless Steel 904L One End Threaded Nipple makes it less machinable than 410 and 304 stainless steels. With its highly alloyed chemistry — 25 % nickel and 4.5 % molybdenum, Stainless Steel 904L Both End Threaded Nipple provides good chloride stress corrosion cracking resistance, pitting and general corrosion resistance superior to 316L and 317L molybdenum enhanced alloys.
Stainless Steel 904L Concentric Swaged Nipple was originally developed to withstand environments containing dilute sulphuric acid. SS 904L Eccentric Swaged Nipple also offers good resistance to other inorganic acids such as hot phosphoric acid as well as most organic acids. 904L Stainless Steel Nipple is easily welded and processed by standard shop fabrication practices. The high content of alloying elements in SS 904L Nipple gives the alloy exceptionally good resistance to uniform corrosion. Grade 904L Nipple provides full resistance in such environments within the entire concentration range of 0 % to 100 %.
