    Generate a magnetic stainless steel head cold causes and solutions

    Stainless Steel head case more data is austenitic stainless steel as material, cold forming processing methods. After the cold worked austenitic stainless steel generally produce strong or weak magnetic, especially for stainless steel head, elbow, deep drawing parts, such as processing a large extent the product.
    

     
    

    Cold worked stainless steel head causes magnetism:
    

    First, when the metastable austenitic stainless steel cold forming, a portion of the austenite martensite transformation, and keep the original austenite coherent in shear mode in the absence of diffusion occurs very short phase transition, students called induced martensitic transformation or deformation induced martensitic transformation;
    

    Second, the martensitic stainless steel generally α 'Markov Hugh and dense hexagonal structure ε martensite two kinds of forms, including α' body-centered cubic structure having a magnetic martensite, ε martensite non-magnetic, but only higher nickel-chromium content, it produced ε martensite.
    

    So commonly used in the stainless steel parts of the organization by the austenite into martensite, it will generate a magnetic. Austenite stability by its chemical composition determines, work-induced martensite and is also related to the intensity of processing.
    

     
    

    If you want to avoid generating magnetic stainless steel head method it can only be based on a material change or for solution treatment.
