摘要/Abstract

摘要： 通过与SUS304对比,研究了高铬铁素体不锈钢TJ21在家电领域应用的耐腐蚀性能、成形性能和食品接触安全性能等。研究表明：TJ21的平面耐蚀性和耐氯离子性能比SUS304更优;与SUS304加工成形性能相比,冲压性能略差,但裁切更容易,焊接性能基本相当;在食品接触安全性能方面,重金属离子迁移量较SUS304低。在家电应用领域,高铬铁素体不锈钢TJ21是奥氏体不锈钢SUS304较为理想的替代材料。

Abstract: Comparing with SUS304, the corrosion resistance, formability and food contact safety performance of high-chromium ferritic stainless steel TJ21 of household appliances were studied. Research shows that the planar corrosion resistance and chloride ion resistance of TJ21 are better than those of SUS304. Relative to SUS304, TJ21 exhibits slightly lower press formability, superior cuttability, and comparable weldability. In terms of food contact safety performance, the migration amount of heavy metal ions is lower than that of SUS304. In the field of household applications, high-chromium ferritic stainless steel TJ21 is a more ideal substitute for austenitic stainless steel SUS304.
