Sachiya Steel International Is One Of The Leading Manufacturer And Exporter Of High Quality Stainless Steel 304H Tube to Union Fittings similar to parker and Swagelok, which is a metal from the nickel chromium family. These Stainless Steel 304H Tube Fittings is considered a super alloy and special metal with specific applications, where it has several characteristics that make is a desirable metal. Stainless Steel 304H Compression Fittings is also resistant to oxidation and can withstand high temperatures, which is further resistant to pressure which makes it perfect for extreme applications. When it is exposed to heat, these Stainless Steel 304H Union Tube Fittings forms a layer to protect the surface from heat and other damage.

Due to all of these characteristics, Stainless Steel 304H Compression Tube Fittings can be used for a wide variety of applications, including sea-water applications. To demonstrate this reaction, these Stainless Steel 304H Ferrule Fittings of annealed were exposed to 1200 Degree F, 1400 Degree F, and 1600 Degree F for 2000 hours contracted about 0.048 %. Measurements were made to determine dimensional stability of Stainless Steel 304H Double Ferrule Fittings, where 1800 Degree F is a temperature at which scaling resistance becomes a significant factor in service.
Extensive investigation of the stability of these SS 304H Union Fittings following exposure for extended periods in the 1000 Degree F to 1800 Degree F temperature range has shown complete absence of embrittling intermetallic phases such as sigma.
