Petromat Oil & Gas Equipment Pvt. Ltd. is a known Supplier, Exporter and Manufacturer of SS 321 / 321H Socket Weld Fittings, which is quickly welded by all common methods including submerged arc. The cold work hardening rate of stainless steel 321 Socket weld Fittings makes it less machinable than 410 stainless steel, but almost like 304. 321 stainless steel Socket Weld Fittings must be water quenched or fully annealed after working to re-attain maximum corrosion resistance. The subsequent is a number of the main applications of SS 321 Socket Weld Fittings, Weld equipment, Chemical processing equipment, and so on. 321 SS Socket Weld Fittings is usually used for Pharmaceutical production, Equipment, and storage units for Food processing, Waste treatment including thermal oxidizers, Aerospace applications, and so on. A182 321H Socket Weld Fittings is additionally utilized in Aircraft exhaust manifolds, Bellows, Furnace parts, Expansion joints, Heat Exchangers.

Grades 321 are the essential austenitic 18/8 steel (Grade 321) stabilised by Titanium (321) additions. Grade 321 SS is the grade of choice for the applications within temperature of up to 900 °C, combining high strength, resistance to scaling and phase stability with resistance to subsequent aqueous corrosion. Grade 321 Stainless Steel have a excellent welding characteristic, are readily brake or roll formed and have outstanding welding characteristics. Post-weld annealing isn’t required. They even have excellent toughness, even right down to cryogenic temperatures. Grade 321 doesn’t polish well, so isn’t recommended for decorative applications.

321H Grade is purpose austenitics Stainless Steel that’s stabilized against designed to works within carbide precipitations temperature range of 427 to 816°C. It’s non-magnetic within the annealed condition and might be hardened only by cold working.
