Due to presence of high nickel alloy 904L stainless steels offer good oxidation resistance. However, the structural stability of this grade collapses at high temperatures, particularly above 400°C.even it have great resistance to warm seawater and chloride attack .UNS N08904 include all standard of stainless steel 316L and contain 6% molybdenum which make it better then stainless steel 316L.

SS 904l Buttweld Pipe Fittings due to its good chemical composition and high nickel content are most demanded product and used grade in the industry.

Oshwin Overseas are global supplier of 904l stainless steel pipe fittings and 904l Flanges Fittings.we provide all third party and test certificate to our client. We believe in providing superior quality as it is not only task of completing order anyhow its matter of trust of our company in our customers mind. we provide fastest delivery and best packing material

SS904L Pipe Fittings 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.

SS904L Pipe Fittings 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.

SS904L  Pipe Fittings 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.

SS904L Pipe Fittings 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.

SS904L Pipe Fittings 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.

SS904L Pipe Fittings 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.
