SS 304 Square Bar is the most widely used austenitic stainless steel product, known for its excellent corrosion resistance, outstanding formability, and superior weldability. It offers a perfect balance of strength, durability, and cost-effectiveness, making it suitable for a wide range of industrial and commercial applications.
At Precision alloy india, we are a reliable SS 304 Square Bar Manufacturer, supplying high-quality square bars in multiple sizes, finishes, and standards to industries such as construction, food processing, chemical, and fabrication.
What is SS 304 Square Bar?
SS 304 (UNS S30400) is an austenitic stainless steel containing 18% chromium and 8% nickel, which provides excellent resistance to corrosion and oxidation.
Unlike martensitic grades, SS 304 is non-magnetic, cannot be hardened by heat treatment, and offers excellent ductility and toughness even at low temperatures.
SS 304 square bars are commonly used in structural frameworks, food-grade equipment, architectural fabrication, and chemical processing units.
