Oshwin Overseas is a leading (SS 904L) ASTM B649 904l Suppliers. SS Round Bar (ASTM B649) are crevice corrosion, stress corrosion cracking, and resistive to adverse conditions. 904L Round Bar (ASME SB649) is an austenitic stainless steel specification providing moderate to superior corrosion resistance. It’s high alloy composition provides excellent resistance to pitting and corrosion in an extensive range of environments. Meanwhile, the low carbon content of SS 904L develops its welding features. 904L Round Bars (ASTM B649 / ASME SB649) with UNS N08904 is widely used in the chemical, pharmaceutical, oil and gas industries.
Oshwin Overseas offer 904L Round Bar (astm b649 904l) in different sizes, grades, diameters and types like ASTM B649, ASME SB649, Roll Bar, Square Bar, Hex Bar, Flat Bar, Round Bar,etc. 904L Stainless Steel Round Bar are available in different length Single Random, Double Random & Cut Length. 904L Pipe can be also found in many other forms such as Round Bar, Square Bar, Hex Bar, Rectangle Bar, Billet Bar, Ingot Bar, Forging etc.

904L Round Bar 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 Round Bar 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 Round Bar 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 Round Bar 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 Round Bar 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 Round Bar 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.
