304 BA stainless steel is a premium material with a bright annealed finish, achieved through a controlled atmosphere annealing process that prevents oxidation.

This finish creates a smooth, semi-mirror-like surface with an elegant sheen that is both visually appealing and corrosion-resistant. While it does not match the full reflectivity of a mirror finish (80% reflectivity), the BA finish (50-60% reflectivity) offers a balance of aesthetics and practicality.

Exceptional formability ensures that 304 BA stainless steel can be bent, rolled, and fabricated without compromising the surface finish. It can also withstand temperatures up to 800°F (427°C) without losing its mechanical properties. You can purchase our 430 BA stainless steel if magnetic stainless steel is needed.
