UNS N08904 ASTM A182 904L stainless steel bars and rods round bar forged


904L is a molybdenum added austenitic stainless steel. As a leading Stainless Steel 904L Round Bar Manufacturer we manufacture all kinds of bars, rods and plates in this grade of steel. The material has superior pitting corrosion resistance and crevice corrosion. The products in this range are highly resistive to acidic corrosion. The addition of ASTM A276 904L Stainless Steel Welding Rod gives the advantage of being resistant to high concentrations to sulfuric acid.


What is 904L Stainless Steel Round Bar?


The UNS N08904 Hex Bar can be used in manifolds, heat exchangers, flanges, valves and tanks. The 904L Stainless Steel Flat Bar is used in structural engineering and in construction industry. Various standards and classes are available in the material and each of them has specific use cases. Our ASME Sa276 Stainless 904L Bar is suitable for kitchen applications, hardware applications and for the production of threaded bars, bolts and nuts. We also produce the high alloyed WERKSTOFF NR. 1.4539 Stainless Steel Bright Bar is bright finished and it could be used in chemical processing, acid production industry, pickling equipment, heat exchangers and in the pollution control equipment.
