904L Stainless Steel Round Bar UNS N08904 1.4539 Super Austenitic Rod, Excellent Acid & Chloride Corrosion Resistance

Our 904L stainless steel round bar (UNS N08904 / EN 1.4539) is super austenitic high-alloy stainless steel, specially manufactured for harsh corrosive working conditions.

1. Superior corrosion performance. With high nickel, molybdenum and copper composition, it has outstanding resistance to dilute sulfuric acid, phosphoric acid, pitting corrosion, crevice corrosion and chloride stress corrosion cracking, much better than 316L and other common stainless grades. Low carbon design reduces intergranular corrosion risk after welding.
2. Stable mechanical & processing property. Good toughness, formability and weldability. Non-magnetic under annealed state. Available surface: black, peeled, bright turned, polished. Diameter range from 4mm to 500mm, length can be cut as customer’s requirement.
3. Strict quality control & complete standards. Produced according to ASTM A276, ASTM B649. Each batch can provide material test certificate (MTC), chemical composition and mechanical test report for inspection.
4. Wide application scope. Widely used in chemical engineering, petrochemical, seawater desalination, marine equipment, pharmaceutical, paper pulp, fertilizer and environmental protection equipment, for pump shafts, valve parts, reactor components and corrosion-resistant fasteners.

We keep large stock for fast delivery. OEM cutting & customized processing are acceptable. Welcome customers to send inquiry for quotation and samples.
