ASTM B649 AISI 904L Round Bars Supplier, Exporter & Manufacturer
904L Round Bar Range: Bright, Black, and Forged Finishes
Leoscor Alloys supplies ASTM B649 904L round bar stock from our Mumbai facility to buyers across India and overseas. Each 904L stainless steel round bar ships in bright, black, or forged finish, matching UNS N08904, WNR 1.4539, and SUS 904L specifications side by side. Sizes run from 6mm to 200mm diameter, with square and hex sections cut from the same heat lot on request. Molybdenum and nickel in the 904L composition give the 904L bar resistance to sulfuric and phosphoric acid attack, which is why chemical processing and desalination plants specify it over standard 316L stock. Every batch carries a mill test certificate traceable to the original heat, and Leoscor Alloys cuts stock sizes to length within 48 hours of order confirmation.
904L Bar Supplier for Export Markets
Buyers in Turkey, Egypt, Singapore, Malaysia, Indonesia, Jordan, South Africa, Oman, Qatar, and Italy source 904L bar stock from Leoscor Alloys for petrochemical, marine, and pollution control projects. As a 904L bar supplier, our company packs bars in wooden crates or bundles for sea freight and issues export documentation, including certificates of origin and third-party inspection reports, before dispatch. Custom lengths and non-standard diameters are cut against a minimum order of 500 kg. Delivery from Mumbai port takes 15 to 20 days to most Middle East and Southeast Asian destinations.

FAQs
A 904L round bar handles sulfuric acid, phosphoric acid, and seawater service in chemical processing, desalination, and marine equipment where standard 316L stainless corrodes too fast.
Nickel content between 23% and 28%, paired with 4% to 5% molybdenum, lets a 904L stainless steel round bar resist pitting and crevice corrosion in chloride-rich environments up to 100°C.
Leoscor Alloys stocks 904L bars from 6mm to 200mm diameter. Square, hex and rectangle sections are cut to customer specified lengths on orders exceeding 500 kg.
Before shipping the order, ensure the 904L bar supplier has a mill test certificate matching the heat number and the 904L bar has certification of compliance to ASTM B649 and ASME SB649.
Industries like Chemical processing, desalination, marine engineering, and pollution control plants use 904L round bars.
