304 Product Guide Product   | 304 Stainless Steel Tolerance Guides product

The most commonly used stainless steel alloy in the world, 304/304L stainless steel offers a great mix of strength and corrosion resistance without being overly specialized. It maintains excellent corrosion resistance in most situations outside of marine environments and maintains its properties in high temperature situations. It is typically used in aerospace, food and beverage industry, pressure containers, architectural designs and trim, cryogenic applications, and chemical processing equipment.

 

We carry 304 in equal angles, unequal angles, half-round bars, hex bars, rectangle bars, round bars, square bars, T-bars, channels, drill rods, fittings, foil, pipe, sheet/plate, expanded sheet, perforated sheet, textured sheet, tread-plate sheet, tape, threaded rod, rectangle tube, round tube, square tube, and sample packs.
