Stainless Steel 446 Threaded Forged Fittings Manufacturer

 

Sachiya Steel International Is one Of The Leading Manufacturer And Exporter Of High Quality Stainless Steel 446 Threaded Forged 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. 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.
