whether Stainless steel 304 have magnetic personality?

Stainless steel types: 1.Austenite size: such as 304, 321, 316, 321, etc.;2.Martensite or iron grain size: such as the 430, 420, 410, etc;Austenite size is non-magnetic or weak magnetic, martensite and ferrite are magnetic.Often used as decorative stainless steel pipe, stainless steel plate of majority is austenite size of 304 stainless steel material, generally is non-magnetic or weak magnetic, but caused by smelting chemical composition may also appear different magnetic fluctuations or processing status, austenite is non-magnetic or weak magnetic, martensite and ferrite is magnetic, due to improper smelting composition segregation or heat treatment, can cause a small amount of martensite in the austenitic stainless steel 304 or ferrite organization.In this way, will with weak magnetic 304 stainless steel.In addition, 304 stainless steel after cold working, the organization structure will be to the martensitic transformation, the greater the degree of cold deformation, martensitic transformation, the magnetic steel.As a number of steel strip, the production of Φ 103 tube, no obvious magnetic induction, Φ 9.5 tube production.Because ling bending deformation is magnetically sensitive to some apparently, rectangular tube production due to the deformation is bigger than circular tube, especially the Angle, more intense magnetic more obvious deformation
