Grade 304 · Cold Drawn · ASTM A276
The 304 stainless steel cold drawn flat bar is manufactured through a precision cold drawing process that pulls hot-rolled bar stock through a die at room temperature. This process work-hardens the material, resulting in improved tensile strength, tighter dimensional tolerances, and a bright, smooth surface finish.
Cold-drawn 304 flat bars are the ideal choice for applications requiring precise dimensions, consistent straightness, and a clean aesthetic appearance. Suitable for architectural trim, precision machinery components, and shaft keys.
