304 Stainless Steel Plate

Making up 50% of worldwide use, 304 stainless steel is the most commonly used stainless steel grade. It is a grade that’s often purchased as a "304/304L dual certified stainless." 304 stainless is a very low carbon, austenitic chromium-nickel steel with high malleability plus good corrosion resistance and superior resistance to intergranular corrosion following welding or stress relieving. The low carbon content in 304 stainless steel limits the formation of harmful carbides to such an extent that this grade may be safely used for most operations of welded construction, as well as where the service temperature is limited to 800 degrees F. As noted above 304 Stainless Steel is austenitic so it is not magnetic in the annealed condition and not hardenable by heat treatment.

Alro stocks 304 stainless steel in many shapes including: tubing, angles, beams, bars, channels, coils, pipes, plates, tubing, and sheets.
