Stainless Steel 904L Tube to Female Pipes

Sachiya Steel International is one of the Leading Manufacturer And Exporter Of High Quality Stainless Steel 904L Tube to Female Pipes, which as well resists general corrosion by many aqueous media. Because of its lower carbon – content, our Stainless Steel 904L Tube Fittings minimizes carbide precipitation, and improves weldability. The protective oxide film of these Stainless Steel 904L Compression Fittings which is formed is adherent in both static and cyclic conditions of heating and cooling, and resistance to carburization is enhanced when a thin film of oxide is being formed on the alloy through pre – oxidation prior to service.

Chromium carbides precipitate in our Stainless Steel 904L Female Connector Fittings at temperatures between 1000 Degree F and 2000 Degree F (540 Degree C and 1095 Degree C). These Stainless Steel 904L Ferrule Tube Fittings has good rupture and creep strength and excellent resistance to oxidation, carburization and suffixation at temperatures up to 816 Degree C.

Consequently, our Stainless Steel 904L Double Ferrule Tube Fittings are similar to other austenitic alloys in that they can be rendered susceptible to inter – granular corrosion (sensitized) in certain aggressive environments by exposure to temperatures of 1000 Degree F to 1400 Degree F (540 Degree C – 760 Degree C). Resistance to hydrogen of these 904L Stainless Steel Female Connector Fittings is excellent and standard materials used in the production of hydrogen in steam / hydrocarbon reforming processes.
