904L Round Bars & Rods

Guru Gautam Steel is India's leading exporter, producer, and supplier of 904L Round Bars. Our WNR 1.4539 Round Bars are available to our valued clients in various diameters, wall thicknesses, and sizes at very reasonable prices. Stainless Steel 904L Round Bars feature 4.5 % molybdenum and 25 % nickel and are resistant to chloride stress corrosion cracking or SCC. This round bar is an austenitic stainless steel type with moderate to outstanding corrosion resistance. Its high alloy composition provides exceptional pitting and corrosion resistance in a wide range of conditions.
Moreover, the low carbon concentration of 904L Round Bars supports the development of its welding properties. The chemical, medicinal, and oil industries all used UNS NO8904 Round Bars. Tanks, valves, heat exchangers, flanges, and pipelines are common uses. The addition of copper to 904L Round Bars improves its appropriateness for parts such as tanks and other goods used to treat sulphuric and phosphoric acid.
Copper inclusion to Alloy 904L Round Bars improves resistance to strong reducing acids, notably sulphuric acid. Corrosion resistance for Grade 904L Round Bars is determined by the nickel content in hot strong acidic solutions. Grade 904L Round Bars, with a nickel concentration of 25%, has shown to be an excellent alternative to most standard stainless steels. Grade 904L Round Bars are less machinable than Grade 410 and Grade 304 because of the cold wear resistance speed. Aviation – jet turbine ports, Industrial Processes, Air Filters, Food Service – equipment and storing, Water Treatment – polythionic acid service, Sewage Disposal – thermal oxidizers are used for 904L Round Bars. All of our products undergo quality tests carried by our experienced staff, along with the product we also send certain certificates, at the time of delivery.
