Sachiya Steel International is one of the Leading Manufacturer And Exporter Of High Quality Stainless Steel 446 Flanges, which is available in dissimilar sizes and shapes for our clients. Our Stainless Steel 446 Slip On Flanges is an age – hardening martensitic stainless combining high strength with the corrosion resistance of stainless steel. Unlike conventional martensitic stainless steels, these Stainless Steel 446 Threaded Flanges is quite weldable, where hardening is achieved by a short – time and simple low – temperature treatment. The strength, corrosion resistance and simplified fabrication can make our Stainless Steel 446 Weld Neck Flanges a cost – effective replacement for high strength carbon steels as well as other stainless grades.

At the solution treating temperature, 1900 Degree F, these Stainless Steel UNS S44600 Blind Flanges is austenitic but undergoes transformation to a low – carbon martensitic structure during cooling to room temperature. This transformation in our Stainless Steel 446 Socket Weld Flanges is not complete until the temperature drops to 90 Degree F. Subsequent heating of these Stainless Steel 446 Lap Joint Flanges to temperatures of 900 Degree F – 1150 Degree F for one to four hours precipitation strengthens the alloy.
This hardening treatment in our Stainless Steel 446 Ring Joint Type Flanges as well tempers the martensitic structure, increasing ductility and toughness. These Stainless Steel 446 Spectacle Blind Flanges is an austenitic heat resistant alloy with oxidation resistance to 1900 Degree F under constant temperature conditions.
