Stainless Steel 304L Tube to Union

Stainless Steel 304L Tube to Union Manufacture

Sachiya Steel International is one of the Leading Manufacture And Exporter of Stainless Steel 304L Tube to Union, which is designed to be as the low carbon version and a medium carbon stainless steel. Stainless Steel 304L Tube Fittings has many of the same characteristics and applications as 316, such as the ability to withstand high temperatures, resistance to oxidation and corrosion, and machinability similar to that of Stainless Steel 304L.

Composed of 20 percent nickel and 25 percent chromium, Stainless Steel 304L Compression Fittings is efficient in reducing environments such as those that contain Sulphur. Combined with its low carbon content, Stainless Steel 304L Union Tube Fittings is also effective at resisting embrittlement. Stainless Steel 304L Ferrule Fittings is commonly utilized in extreme conditions, such as furnace manufacturing and heat treating equipment. While both hot and work practices can be applied, cold working is not commonly done on Stainless Steel 304L Double Ferrule Fittings; however, it is the only way to work – harden the metal.

This resistance to cold temperatures is useful in cryogenic environments, as SS 304L Tube Fittings is incredibly tough. However, SS 304L Compression Fittings can be subject to thermal shock and therefore should be treated and hot – worked with care. SS 304L Union Fittings has ultra – high nickel content of 34 percent to 37 percent also provides high resistance to chloride stress corrosion cracking and embrittlement from the precipitation of sigma phase in most furnace atmospheres.
