Based in Kolkata, India, Neil Metals is a well-known producer and supplier of premium 904L stainless steel bars and rods. Our SS 904L bars and rods are designed to satisfy difficult industrial requirements and are renowned for their exceptional corrosion resistance, especially in harsh acid and chloride environments. These bars are perfect for crucial applications in sectors like chemical processing, marine, and pharmaceuticals because they are precisely manufactured and adhere to international standards. Neil Metals provides tailored solutions to domestic and international clients looking for long-lasting, high-performance stainless steel products, with a strong emphasis on quality, prompt delivery, and client satisfaction.
Stainless Steel 904L is an austenitic, low-carbon, high-alloy steel that contains 19–23% chromium, 23–28% nickel, 4–5% molybdenum, and 1-2 percent copper. Particularly in harsh conditions with phosphoric or sulphuric acids, this special composition offers exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking. SS 904L bars and rods have excellent formability, good toughness, and tensile strength ranging from 490 to 710 MPa. The alloy is appropriate for demanding and long-lasting structural applications because it is non-magnetic, stable over a broad temperature range, and maintains its mechanical integrity under corrosive and high pressure conditions.
