Sachiya Steel International is one of the Leading Manufacture And Exporter of Stainless Steel 317L Tube to Union, which is prone to inter – granular corrosion in the as – welded state. The “L” in the name of Stainless Steel 317L Tube Fittings refers to the “low carbon content”, which can be used in the welded form without being susceptible to inter – granular corrosion. When exposed to temperatures ranging from 800 degrees Fahrenheit – 1500 degrees Fahrenheit, Stainless Steel 317L Compression Fittings is prone to carbon precipitation. After the welding process, annealing will help improve the resistance of Stainless Steel 317L Union Fittings to corrosion.

Stainless Steel 317L Ferrule Fittings has the same composition as regular 317L Stainless Steel, with the exception of the carbon content, which is below 0.03 %. Physical properties and corrosion resistance are excellent; on the other hand, Stainless Steel 317L Double Ferrule Fittings provides protection against inter – granular corrosion in the welded condition. When in excellent temperatures, Stainless Steel 317L Union Tube Fittings also can resist inter – granular corrosion.

It is advisable to apply 317L Stainless Steel Union Fittings when presence in the carbide precipitation range cannot be avoided or when annealing after the welding process is impractical. When exposed to the carbide precipitation range for too long, 317L Stainless Steel Tube Fittings may become damaged and inter – granular attack may be more likely to take place.
