304 Stainless Steel Sheet

304 is in the “Austenitic” group (or chrome-nickel series) of stainless steels. It is not hardenable by heat-treatment and it is not magnetic. Hardness is accomplished by cold-working, which may create some magnetism). Tougher and more ductile than most ordinary steels, 304 (and other austenitic), also has excellent mechanical properties and weldability and good corrosion resistance.

SSheet Diagramtocked in full sheets, generally 48 x 120; cut pieces available.

AED stocks 304 stainless sheet in a variety of thicknesses, primarily in the #4 finish, (which is a polished or “brushed” finish). The “polished” finish does NOT refer to a “mirror-type” finish. See 430 Bright Annealed (below) for “mirror” finish. Mill finish available on thicker gages. Meets ASTM A240 and others.
