SS 904L Fasteners Supplier

904L Stainless Steel is an a commercial grade of authentic stainless steel which has a very low carbon content and is non stabilized. It is high in nickel and copper alloy and is blended with copper to increase its resistance to acids like sulphuric acid which is also a good reducing agent. This is usually resistant in both mild as well as aggressive condition. It has a high percentage of nickel and molybdenum.  It is also resistant to other things like crevice and stress corrosion. It is tough, weldable and is not magnetic but gives superb formability. Alloy 904L, UNS N08904 are the usual trade names for 904L-end commercial programs. These alloy fasteners are made of SS 904L . These Alloy 904L  Fasteners are designed to have extremely great strength and creep-rupture qualities at higher temperature ranges and demands. Besides this, these conventional designed metal fasteners have a great level of resistance towards heat and deterioration. Again, perfection machining and design guarantees twisting free, zero mistake fasteners with close specifications and ideal completes.

This Alloy 400 is a lower alternative when it comes to costing and has a much lower corrosion resistance. It is highly resistant to crevice corrosion and pitting and the 2205 grade has greater mechanical strength in comparison. Used for heater elements, in substance and meals handling, in atomic technological innovation, and for leading to electrodes. Standard product forms are round, hexagon, extruded area, apartments, developing stock, pipe, tube, plate, sheet, strip, and wire.
