Is 304 stainless steel magnetic?

1:304 Stainless steel, which belongs to the metastable state, belongs to a single austenitic microstructure state after annealing and does not have magnetic properties. However, after cold working deformation (such as stamping, stretching, rolling, etc.), part of the austenite structure will undergo phase transformation (generally mutated into martensite) and have magnetic properties. According to the size of the deformation, the magnetic strength is different

2: At present, there are many kinds of sink processing technology, there are welding forming, one stretch forming, the following stretch panel welding forming several ways, if the use is 304 material welding forming, this case is the use of annealed state of the plate for processing, generally not with magnetic or there will be a little weak magnetic (because the sink surface will have surface treatment); If it is an integrated stretch molding tank that needs to be stretched several times, the general intermediate process will be annealed (due to the influence of work hardening, annealing is to be able to process) and then stretched, after which there is generally little annealing (if the annealing needs to increase the cost, and there is no need to annealing again for 304). Therefore, if it is an integrated stretch molding product, it is a normal phenomenon to use 304 stainless steel materials after processing with magnetic
