Oshwin Overseas is one of the leading Industrial Fasteners Manufacturers, Fastener Distributors and Fastener Suppliers. We also Deal in Aerospace Fasteners and Concrete Fasteners. Oshwin Overseas offers all Types of Fasteners such as Stainless Steel Bolts and Nuts, Stainless Steel Washer, Stainless Steel Screws etc and a comprehensive range of engineered 904L Stainless Steel Fasteners in different types, grades and dimensional specifications. Stainless Steel 904L Fasteners inherent anti-corrosive properties allowing 904L to be made into bolts, anchor bolt, nuts, hex nut, washers, studs, screw, socket head cap screw, socket screw, as well as a wide variety of other fasteners.
These Stainless Steel Fasteners are made of high grade materials such as SS 904L (1.4539/UNS N08904). Offered in both standard sizes and customized sizes, these 904L Stainless Steel Fasteners conforms to standards like BIS, BS, DIN, ASTM etc. 904L Fasteners have less corrosion resistance than molybdenum-free grades such as 304L and 316L. For the maximum stress corrosion cracking resistance in critical environments the steel should be solution treated after cold working the parts into fasteners: such as bolt, nuts, Screw and Washer.

SS 904L with UNS N08904 also known as 2RK65 Stainless Steel, RVS 904L, Uranus B6, SEW 400, vdtüv 421, Acier 904L, сталь 904l and 904l teräs is an austenitic stainless steel. SS904L have a good high nickel resistance to warm sea water and high chloride environments, some of the major applications of grade 904L stainless steel Fasteners include – Wiring in electrostatic precipitators , Phosphoric and sulphuric acid, processing plants,Production and transport of sulphuric acid, Metal pickling in sulphuric acid, Production and concentration of phosphoric acid, seawater ,brackish water,condensers, Paper and allied industries,Gas washing, Chemical and pharmaceutical industries.
904L Fasteners Corrosion Resistance
904L gives good resistance to both organic and inorganic acids.The addition of copper in 904L grade gives excellent corrosion resistance against nickel stainless steels, to sulphuric, phosphoric, acetic acids, hydrochloric acids, etc. It also gives a high resistance to pitting in chloride solutions, an excellent resistance to both crevice and stress corrosion cracking.The 904L is much better than austenitic stainless steels due to the higher alloying of nickel and molybdenum.The high percentage of chromium content in 904L gives and maintains a passive film which protects the material in many corrosive environments.
904L Fasteners Cold Forming
Cold forming 904L can be done easily. The composition of molybdenum and nitrogen implies more powerful processing equipment may be needed.Most of the time more common methods like cooling with air or water etc are used.
904L Fasteners Hot Forming
Hot and heat forming should be done after uniform heating.Complete annealing should be done before any hot forming in order to retain maximum ductility and corrosion resistance property. It is very important that the whole process should be done above 1100°C.
904L Fasteners Machining
The machining of 904L requires proper care to achieve the expected result. The cutting speed should be slow and proper care should be taken while doing so.
904L Fasteners Welding
The 904L material should be allowed to cool in between, preferably to below 150°C temperatures. To obtain good welding properties welded condition, filler material shall be used.Because of high thermal expansion, welding must be carefully planned in advance to ensure that distortion of the welded joint can be kept under control.
904L Fasteners Heat Treatment
The heat treatment should be accompanied by cooling in water or air immediately. This treatment should be applied for both solution annealing and stress relieving from the 904L material.
