The common marking methods on the market are 06Cr19Ni10, SUS304, of which 06Cr19Ni10 generally means national standard production, 304 generally means ASTM standard production, and SUS304 means Nissan marked production. 304 is a general purpose, it is widely used to make equipment and parts that require good comprehensive properties (corrosion resistance and formability). In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 18% chromium and more than 8% nickel. 304 stainless steel is a grade of stainless steel produced according to American standards.
It is characterized by good toughness and corrosion resistance. Austenitic stainless steel 304 and 316 have no magnetism themselves, and are generally demagnetized after processing, but they may not be completely eliminated, and there will be relatively small magnetism, that is, micromagnetism. The presence of magnetism does not mean that it is not a stainless steel ball, such as martensitic stainless steel balls 420 and 440, which can be attracted by magnets, commonly known as stainless iron.
