Is 304 nerūdijantis plienas magnetinis?

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 dabar, ten yra daug rūšių iš kriauklė apdorojimas technologija, ten yra suvirinimas formavimas, vienas tempimas formavimas, the following stretch panel suvirinimas formavimas keli būdai, if the use is 304 medžiaga suvirinimas formavimas, šis atvejis is the use of annealed state of the plate for processing, generally not with magnetic or there be a little weak magnetic (nes the sink surface will have surface treatment)% 3b If it is an integrated stretch molding tank that needs to be stretched keli 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 paprastai little annealing (if the annealing needs to increase the cost, and there is no need to annealing again for 304). Todėl, jei it is an integruotas tempimas liejimas produktas, it is a normalus reiškinys to naudojimas 304 nerūdijantis plienas medžiagos po apdorojimo su magnetiniu
