AISI 304/304L stainless steel bars offer excellent corrosion resistance, durability, and machinability. Available in round, square, hex, and flat forms for construction, machinery, food equipment, and chemical applications.
AISI 304/304L stainless steel bar is one of the most widely used stainless steel materials across global industries. With a chromium–nickel austenitic structure, this grade provides excellent corrosion resistance, good strength, reliable weldability, and great surface cleanliness—making it suitable for environments requiring hygiene, chemical stability, and long service life.
Compared with 304, 304L has a lower carbon content, ensuring better weldability and reducing the risk of carbide precipitation in heat-affected zones. This makes 304/304L an ideal material for equipment used in food processing, chemical containers, architectural structures, and general mechanical components.
