含铬铁素体不锈钢由于具有耐蚀性好和价格低廉等优点而深受各方欢迎,但因其深冲成型性和焊接性能差而受到限制。本文介绍我所新研制的含Cr铁素体不锈钢—My_1(民用1号),My_2(民用2号)的主要性能和使用效果。My_1、My_2不锈钢不仅具有铁素体不锈钢的优点,同时具有良好的冶金生产工艺性能,深冲压成型和焊接工艺性能,冷作硬化倾向小,厚3～4mm的热轧带钢可直接冷轧至很薄的薄带,中间不必软化退火;不锈钢笔套、电吹风外壳等均可多道次连续深冲压成型,取消中间退火;可用高频焊,氩弧焊;闪光对焊等工艺进行焊接。高频直缝焊接钢管各项性能优良,已用于制作多种家具、自行车挡泥板、外文打字机另件等。产品的大量生产及使用证明其成型工艺性,耐蚀性等均优良,推广使用后不仅可节约大量贵金属镍,而且可简化冷加工工序,减少能源损耗,减少三废污染,降低生产成本,可使产品升级换代,提高市场竞争能力。
Chromium-containing ferritic stainless steel is popular with all parties due to its good corrosion resistance and low cost, but it is limited by its deep drawing formability and poor weldability. This article describes the newly developed my Cr-containing ferritic stainless steel-My_1 (civilian No. 1), My_2 (No. 2 civilian) the main performance and the use of results. My_1, My_2 stainless steel not only has the advantages of ferritic stainless steel, but also has good metallurgical production process performance, deep drawing and welding process performance, cold hardening tendency, the thickness of 3 ~ 4mm hot-rolled strip can be directly cold-rolled Thin strip, the middle without softening annealing; stainless steel pen cover, hair dryer shell and so on can be multi-pass continuous deep drawing, cancel the intermediate annealing; available high-frequency welding, welding, flash welding and other welding process. High-frequency straight seam welded steel pipe of various excellent performance, has been used in the production of a variety of furniture, bicycle fenders, foreign typewriters and other pieces. Mass production and use of products proved its molding process, corrosion resistance and so on are excellent, not only can promote the use of a large number of precious metal nickel savings, and can simplify the cold processing processes, reduce energy consumption, reduce waste pollution, reduce production costs, make products Upgrade, improve market competitiveness.
