There are many types of stainless steel, which can be divided into several categories according to the organizational structure at room temperature: 1. Austenitic type: such as 304, 321, 316, 310, 201, etc.; 2. Martensite or ferrite type: such as 430, 420, 410, etc.; The austenite type is non-magnetic or weakly magnetic, and martensite or ferrite is magnetic. Most of the stainless steels used as decorative tube sheets are austenitic type 304 materials, which are generally non-magnetic or weakly magnetic.
