钢铁材料是国民经济建设不可或缺的最重要金属原材料,由于使用量巨大已造成对环境和资源的重大影响。因此,开发“长寿命、可循环、高性能”钢铁材料是国际社会应对资源枯竭和环境恶化的重要手段。采用不锈钢替代镀锌先进高强钢,可实现近100%回收与再利用,从而减轻锌资源储量不足的压力,降低镀锌板回收过程中烟尘排放对环境造成的破坏性影响。可是,传统含镍不锈钢成本过高;而传统的节约 Steel materials are the most important metal raw materials indispensable to national economic construction, and have caused significant environmental and resource impacts due to the huge amount of usage. Therefore, the development of “long-life, recyclable, high-performance” steel materials is an important means for the international community to cope with resource depletion and environmental degradation. The use of stainless steel instead of galvanized advanced high-strength steel, can achieve nearly 100% recovery and reuse, thereby reducing the pressure of insufficient zinc resources reserves and reduce emissions of galvanized sheet soot emissions on the environment caused by the devastating impact. However, the traditional nickel-containing stainless steel cost is too high; the traditional savings
