Sachiya Steel International Is One Of The Leading Manufacturer And Exporter Of High Quality Stainless Steel 317 Tube to Union Fittings, which is a typical austenitic 18 / 8 stainless steel SS, with the expansion of titanium. Our Stainless Steel 317 Tube Fittings similar to parker and Swagelok has a carbon content restricted to exclude the lower end of Stainless Steel 317 range, so is the grade of choice for high temperature applications. These Stainless Steel 317 Compression Fittings have excellent toughness, even down to cryogenic temperatures, although other grades are normally used in sub – zero environments.
Our Stainless Steel 317 Union Tube Fittings comprises of 11 % to 15 % nickel and 18 % to 20 % chromium. These Stainless Steel 317 Ferrule Fittings is molybdenum comportment austenitic stainless steel which is similar to grade 316, be that as it may, by method for higher molybdenum substance. Our Stainless Steel 317 Double Ferrule Fittings provides higher creep, tensile strength, and stress – to – rupture, at high temperatures than regular stainless steels.
These 317 Stainless Steel Union Fittings is a low carbon grade that offers imperviousness to sharpening, all through welding and other techniques. Our 317 Stainless Steel Tube Fittings i has excellent forming and welding qualities, and the addition of columbium and tantalum helps for exceptional inter – granular corrosion resistance. These 317 Stainless Steel Compression Fittings is similar to grade 321, but with slightly improved corrosion resistance in strongly oxidizing environments.
