抗磁不锈钢在使用中存在的问题及解决办法

奥氏体不锈钢材料的磁化率很低,因此在高科技产品中常常被当作抗磁材料来使用。由于材料的牌号不同,其磁化率也有所不同,另外,如果所使用材料的状态不对,材料的抗磁性能也将受到较大的影响,因此选择合适的材料牌号和进行必要的固溶处理是抗磁材料满足其产品技术性能要求的先决条件。

提升2Cr15Mnl5Ni2N不锈钢抗磁性工艺研究

2Cr15Mn15Ni2N奥氏体抗磁不锈钢是一种性能优良的抗磁不锈钢,为了满足高抗磁性零件需求,通过采用抗磁性检测、金相组织分析和晶粒度检测,就固溶保温温度和保温时间对2Cr15Mn15Ni2N奥氏体抗磁不锈钢的抗磁性的影响进行了工艺研究。结果发现,1120℃固溶,延长保温时间,当2Cr15Mn15Ni2N抗磁不锈钢晶粒度长大到6级、晶粒度均匀一致时,抗磁性达到了≤Ⅱ级,满足了产品技术要求,解决了产品固溶抗磁性不足的技术问题,提出了生产过程工艺控制参数,可为后续同类问题的处理提供借鉴。

The Development of a New Anti-electromagnetic Radiation Fabric

By the study of electromagnetic shielding principle,we have designed some new style fabrics for anti-electromagnetic radiation through the research of raw materials and fabric texture,and solved the key technical problems such as the manufacture of composite yarn which composed of stainless steel filament and cotton yarn.As a newly developed high technology material,the new style anti-electromagnetic radiation fabric was woven by the special yarn composed of stainless filament and nature fiber.The new fabric overcomes the defect in the production and service of the shielding fabrics at present and satisfies the people's requirement the routine job and life.With further improvement,it can be widely used in aviation,navigation and military project,underground project and so on.
