Stainless steel 404 has excellent corrosion resistance owing to the presence of copper and chromium in its composition. Therefore, it is increasingly replacing 304 steel in many applications. Stainless steel 404 allows for significant cost savings due to the ease of fabrication. It is magnetic, and has low thermal expansion, so there is less distortion of alloys during fabrication.
