Ojas Pipes and Tubes, located in Kolkata, India, stands out as a top manufacturer and supplier of Stainless Steel 904L Round Bars and Rods, celebrated for their exceptional quality, precision, and durability. With a focus on high-performance alloys, Ojas provides 904L stainless steel products that are specifically designed to endure highly corrosive environments, including those found in marine, chemical, and pharmaceutical sectors. Committed to upholding international standards and ensuring customer satisfaction, the company guarantees timely deliveries and tailored dimensions. Engineers and fabricators trust their 904L round bars and rods for critical applications that demand outstanding resistance to acids and extreme conditions.
Stainless Steel 904L Round Bars and Rods boast high levels of chromium (19–23%), nickel (23–28%), molybdenum (4–5%), and a touch of copper (1–2%) to provide remarkable corrosion resistance. This low-carbon austenitic alloy excels in resisting pitting, stress corrosion cracking, and crevice corrosion. With a tensile strength of around 490 MPa, yield strength of about 220 MPa, and an elongation of roughly 35%, it delivers impressive mechanical performance even in harsh environments. 904L is non-magnetic, weldable, and can be easily machined with the right tools, making it ideal for specialized industrial applications.
