Sachiya Steel International Is One Of The Leading Manufacturer And Exporter Of High Quality Stainless Steel 904L Hydraulic Fittings, which is not very electrically or thermally conductive and is non – magnetic. Stainless Steel 904L Hydraulic Type Fittings is a corrosion and heat resistant 12 % chromium steel, and is the most widely used of the harden able stainless steels. Heat treated Stainless Steel 904L Forged Hydraulic Fittings has mechanical properties comparable to the engineering alloy steel, coupled with the additional benefit of good corrosion resistance. 904L Stainless Steel Hydraulic Fittings is used for a variety of household and industrial applications such as screws, machinery parts, car headers, and food-handling equipment.
904L Stainless Steel Hydraulic Type Fittings contains both chromium (usually 18 %) and nickel (usually 8 %) metals as the main non-iron constituents. 904L Stainless Steel Forged Hydraulic Fittings stains less easily than other iron-based metals, but it’s not literally stainless. SS 904L Hydraulic Fittings has a higher corrosion resistance than regular steel and is widely used because of the ease in which it is formed into various shapes.
Grade 904L Hydraulic Fittings is also used in the architectural field for exterior accents such as water and fire features. The standard specification for carbon and high – strength low – alloy structural steel shapes, quenched and tempered Type 904L Hydraulic Fittings for structural plates intended for use in bridges. AISI 904L Hydraulic Fittings is highly resistant to atmospheric corrosion, where maximum corrosion resistance is obtained by hardening and polishing.
