All kinds of tableware: should choose martensitic stainless steel (0Cr13, 1Cr13, 2Cr13, 3Cr13).
High manganese steel is not recommended for the presence of acids, alkalis and other chemical environments. It can be widely used in the manufacture of tableware, indoor water storage equipment and Engineering "non critical structural parts" in the daily use environment.
