我公司核电产品中所涉及的奥氏体不锈钢材料对磁导率有严格要求,而按国标采购的该类钢材,因为化学成份或工艺的局部差异会导致材料磁导率的不同,另外在产品生产、转运、加工、焊接过程中也会显著影响磁导率的高低,因此采用何种稳定有效的工艺措施来保证产品磁导率合格就显得尤为关键。 The austenitic stainless steel materials involved in our nuclear products have strict requirements on the permeability, but the steel products purchased according to the national standard, because of the chemical composition or process of local differences will lead to different material permeability, the other in the product Production, transport, processing, welding process will also significantly affect the level of permeability, so what kind of stable and effective process measures to ensure the permeability of the product is particularly crucial.
