Product Description
1.4541 AISI 321 Alloy Cold Rolled Stainless Steel Coil 2B Finish
There are many kinds of stainless steel, which can be divided into several categories according to the structure at room temperature:
1. Austenitic type: such as 304, 321, 316, 310, etc.;
2. Martensite or ferrite type: such as 430, 420, 410, etc.;
The austenitic type is non-magnetic or weakly magnetic, and the martensite or ferrite is magnetic.
As mentioned above, austenite is non-magnetic or weakly magnetic, while martensite or ferrite is magnetic. Due to component segregation or improper heat treatment during smelting, a small amount of martensite or ferrite in austenitic 304 stainless steel will be caused. body tissue. In this way, 304 stainless steel will have weak magnetism.
In addition, after cold working of 304 stainless steel, the structure will also be transformed to martensite. The greater the cold working deformation, the more martensite transformation, and the greater the magnetic properties of the steel. Like a batch of steel strips, Φ76 tubes are produced without obvious magnetic induction, and Φ9.5 tubes are produced. The magnetic induction is more obvious due to the large deformation of the bending and bending. The deformation of the square rectangular tube is larger than that of the round tube, especially the corner part, the deformation is more intense and the magnetic force is more obvious.
In order to completely eliminate the magnetic properties of 304 steel caused by the above reasons, high temperature solution treatment can be used to restore the stable austenite structure, thereby eliminating the magnetic properties.
In particular, it should be pointed out that the magnetic properties of 304 stainless steel caused by the above reasons are completely different from those of other materials such as 430 and carbon steel, which means that the magnetic properties of 304 steel always show weak magnetic properties.
