How to remove the magnetism of 304 stainless steel

1. Chemical equivalent component control is not in place.
In order to reduce the cost, the general manufacturers control the lower limit of Ni, between 8.0 and 8.2%. When Cr/Ni reaches a certain value, a certain amount of ferrite appears in the tissue, and ferrite is magnetic. At this point the 1050 ~ 1080 solid solution treatment can completely into the ferrite austenite is not magnetic.Best seller bright 321 stainless steel bar 10 mm
2. Cold work hardening.
When austenite stainless steel deforms martensite during cold processing, the deformable martensite increases the strength of stainless steel, while the deformable martensite is magnetic. Solid solution treatment and even annealing can make the deformation martensite disappear, but the strength of the steel will decline.
If you want to guarantee the intensity of cold working, weak magnetism or even no magnetism, you can use the following demagnetization method:
1. Reduce Cr/Ni value according to the phase diagram principle, especially increase the content of Ni and Mn to the upper limit. Before cold processing, upper limit solid solution treatment was performed to control grain size 4 on the premise of guaranteeing the surface. Can reduce the magnetic after cold processing.Steel Bar Grating Especificaciones
2. Generally 304 has some weak magnetism after cold processing. When the austenite tissue is transformed into a martensite by a knock or other impact, there is a certain amount of magnetism. Heat to 1050 degrees and water quench to remove the magnetism.Doblador de tubo de acero inoxidable de 1 pulgada
