Where is the difference between stainless steel 304 and Q235?
304 stainless steel, Q235 is carbon steel (that is, ordinary steel plate, Yi Shengxiu). 304, generally do food grade container parts or some products that need anti rust, Q235 is used as some general purpose, no need for rust prevention!! 304, it can be antirust, mainly because of the relatively high nickel content!
Q235 is a common carbon structural steel, that is, the original standard A3 material, the general construction steel, steel channel, I-beam, ordinary steel pipe belong to this steel. The main component of Q235 is Fe, and the magnet can be adsorbed.
304, SUS304 belongs to austenitic stainless steel, which is equivalent to 0Cr19Ni10 austenitic stainless steel in our country. The main component is alloy, without magnetism (magnet can not adsorb).
