Sachiya Steel International is one of the Leading Manufacturer And Exporter Of High Quality Stainless Steel 347 Nipple, in which silver brazing compounds are known to cause stress cracking in nickel – based alloys. Rupture and creep properties of SS 347 Hexagon Reducing Nipple shown in this bulletin are typical of material receiving this low – temperature treatment. Slow response of Stainless Steel 347 Hexagon Nipple to age hardening enables parts to be welded and directly age – hardened without an intermediate stress relief. If Stainless Steel 347 One End Threaded Nipple is cold – worked and / or precipitation – hardened, silver brazing compounds should not be used.
Also, SS 347 Both End Threaded Nipple containing cadmium are best avoided; while cadmium has not been shown to cause cracking by itself, it can aggravate cracking from other sources. Room – temperature properties of welds in Stainless Steel 347 Concentric Swaged Nipple receiving the low temperature anneal and / or age can be compared with results of the high – temperature anneals and / or age.
Additional properties of welds in Stainless Steel 347 Eccentric Swaged Nipple is annealed at 1950 Degree and aged at 1400 Degree F to 1200 Degree F, hold at 1200 Degree F for a total aging time of 20 hours. Welding was by the manual gas tungsten-arc process, using 347 Stainless Steel Nipple, where these welds were found satisfactory in bend tests and radiographic examination.
