Sachiya Steel International is one of the Leading Manufacturer And Exporter of 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.

Sachiya Steel International is one of the pioneer Manufacture and Exporter of Stainless Steel 446 Forged Threaded Fittings, which is commonly used for various fasteners and pins that require strength and resistance to galling.
Because of its high – hardness capability, Stainless Steel 446 Forged Threaded Elbow is seldom welded, because the additions of 4 % silicon and 8 % manganese inhibit wear, galling, and fretting.
However, if welding is necessary, the parts of Stainless Steel 446 Forged Threaded Tee should be preheated and maintained at about 500 Degree F, welded, and then immediately given a 6 hour – 8 hour anneal at 1350 Degree F / 1400 Degree F with a slow furnace cool.The parts of Stainless Steel 446 Forged Threaded Cross should not be allowed to cool below 500 Degree F between welding and annealing, where high welding heat inputs should be used.
To obtain mechanical properties of Stainless Steel 446 Forged Threaded Cap in the weld similar to those in the base metal, welding consumables of like composition should be considered.
In cutlery applications, grinding and polishing are very important, where Stainless Steel 446 Forged Threaded Fittings works well in these operations.Stainless Steel 446 Forged Threaded Fittings | Stainless Steel 446 Forged Threaded Fittings | Stainless Steel 446 Forged Threaded Fittings | Stainless Steel 446 Forged Threaded Fittings | Stainless Steel 446 Forged Threaded Fittings | Stainless Steel 446 Forged Threaded Fittings Do not overheat while grinding Stainless Steel 446 Forged Threaded Coupling, since both the hardness and corrosion resistance may be lowered.
Typical applications of Stainless Steel 446 Forged Threaded Union are large airframe structural components and injection moulding equipment.
