AB Steel is one of the largest exporter, manufacturer and supplier of Stainless Steel 304 Round Bars in India. Our SS 304 Bars (also referred as WNR 1.4301) are accessible to our valuable customers in different range of diameters, wall thicknesses and sizes. Also known as UNS S30400 Bars, these 304 Stainless Steel bars has an expansion coefficient nearly equal to that of modern concrete. If this were not so, it would cause problems through additional longitudinal and perpendicular stresses at temperatures different from the temperature of the setting.

Our SS 304 bars are crafted to meet the stringent requirements of ASTM A276 and ASME SA276 standards, as well as international specifications including EN, DIN, JIS, BS, and AISI. With a balanced composition of approximately 18% chromium and 8% nickel, our SS 304 forged bars deliver superb corrosion resistance, strength, and durability—making them ideal for applications across chemical processing, food production, marine, and architectural sectors.

Our SS 304 round bars are available in a versatile range of shapes and forms to suit diverse applications and fabrication needs. Whether you require round, square, hex, flat, rectangle, billets, forgings, or custom profiles, we have you covered. Additionally, we offer finishes such as bright polished, rough turned, NO.4, matt, and BA finishes.
