Sachiya Steel International Is One Of The Leading Manufacturer And Exporter Of High Quality Stainless Steel 446 Pipe Fittings, which is subject to stress corrosion cracking in hot, a concentrated caustic alkali. When stainless steel compounds are present as well, or for ammonium hydroxide service, these Stainless Steel 446 Compression Pipe Fittings is suggested. To avoid stress corrosion cracking, our Stainless Steel 446 Ferrule Pipe Fittings fabrication should be fully stress relieved prior to use. A minimum treatment of 1650 Degree F for 1 hour is suggested in our SS 446 Double Ferrule Pipe Fittings, but 1800 Degree F – 1850 Degree F for 1 hour preferred.

This Stainless Steel 446 Accessories is a high strength nickel base super – alloy used for cryogenic temperatures up to long term service at 1200 Degree F. Our 446 Stainless Steel Compression Pipe Fittings is readily fabricated and may be welded in either the annealed or precipitation (age) hardened condition. These 446 Stainless Steel Ferrule Pipe Fittings will show a contraction after precipitation hardening, where annealing is done at 1700 Degree F – 1850 Degree F, and then air cool or faster.
Our 446 Stainless Steel Double Ferrule Pipe Fittings is a low carbon, high purity, nitrogen-bearing “super-austenitic” stainless alloy. These 446 SS Accessories was designed to be a seawater resistant material and has since been demonstrated to be resistant to a broad range of very corrosive environments.
