Relationship between austenitic 304 stainless steel coil and martensite size 304 stainless steel coil

Date:Nov 13, 2018


Austenite is non-magnetic or weakly magnetic, martensite or ferrite is magnetic.


Stainless steel A wide variety, at room temperature according to the organizational structure can be divided into several categories:


Relationship between austenitic 304 stainless steel coil and martensite size 304 stainless steel coil


It is mentioned above that austenite is non-magnetic or weak magnetic, and martensite or ferrite is magnetic, due to smelting component segregation or improper heat treatment, will cause austenitic 304 stainless Steel in a small number of martensite or ferrite tissue.In this way, 304 stainless steel will have a weak magnetism.


Relationship between austenitic 304 stainless steel coil and martensite size 304 stainless steel coil


In addition, 304 stainless steel after cold processing, the tissue structure will also be converted to martensite, the greater the deformation of cold processing, the more martensite conversion, the greater the magnetism of steel.


In order to completely eliminate the magnetic properties of 304 steel caused by the above reasons, the stable austenitic tissue can be restored by high temperature solidification treatment, thus eliminating magnetism.
