Sachiya Steel International Is One Of The Leading Manufacturer And Exporter Of High Quality Stainless Steel 347 Hydraulic Fittings, which is used where both the properties of steel and corrosion resistance are required. High oxidation resistance in air at ambient temperature is normally achieved with addition of a minimum of 13 % (by weight) chromium in Stainless Steel 347 Hydraulic Type Fittings, and up to 26 % is used for harsh environments. When parts of Stainless Steel 347 Forged Hydraulic Fittings are forced together, the oxide layer can be scraped off, allowing the parts to weld together.
When forcibly disassembled, the welded SS 347 Hydraulic Forged Fittings may be torn and pitted, a destructive effect known as galling. SS 347 Hydraulic Fittings contain a maximum of 0.15 % carbon, a minimum of 16 % chromium, and sufficient nickel and / or manganese to retain an austenitic structure at all temperatures from the cryogenic region to the melting point of the alloy. There are various shapes and surface finishes of 347 Stainless Steel Hydraulic Fittings to suit the environment the alloy must endure.
347 Stainless Steel Forged Hydraulic Fittings is generally highly resistant to attack from acids, but this quality depends on the kind and concentration of the acid, the surrounding temperature, and the type of steel. Like other steels, 347 Stainless Steel Hydraulic Type Fittings is a relatively poor conductor of electricity, with significantly lower electrical conductivity than copper.
