Based in Kolkata, India, Neil Metals is a well-known manufacturer and supplier that specialises in offering high-quality 904L rectangular stainless steel bars for demanding industrial applications. Our SS 904L rectangular bars are made with premium materials and state-of-the-art techniques, and they are renowned for their exceptional weldability and corrosion resistance. These bars are perfect for conditions with high temperatures, strong acids, and chloride attack. Neil Metals guarantees that every product satisfies exacting international quality standards and provides personalised finishes and dimensions. We are dedicated to providing our clients in India and overseas with performance, dependability, and value, and we serve sectors like chemical processing, marine, and pharmaceuticals.
High concentrations of chromium (19–23%), nickel (23–28%), molybdenum (4–5%), and trace amounts of copper (1–2%) are found in stainless steel 904L, a low-carbon austenitic alloy. Particularly in environments that are acidic and chloride-rich, this composition provides exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking. Rectangular SS 904L bars are tough and ductile, with a tensile strength of approximately 490–710 MPa. The alloy is ideal for severe service applications because it is non-magnetic under all circumstances and maintains its mechanical integrity over a broad temperature range.

Rectangular bars made of stainless steel 904L are frequently used in industries that demand exceptional corrosion resistance, particularly in harsh chemical and maritime environments. They are perfect for use in chemical storage tanks, pulp and paper manufacturing, seawater handling systems, heat exchangers, and condenser tubes. 904L bars guarantee sanitary, contamination-free operation in the food processing and pharmaceutical sectors. Because of their exceptional resistance to acetic, phosphoric, and sulphuric acids, they are also utilised in gas scrubbers, power plants, and acid production units. They are appropriate for both structural and functional components due to their high strength, non-magnetic nature, and long-term durability.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
