2025年8月5日,浦项股份有限公司成功申请一项名为“马氏体系不锈钢及其制造方法”的专利,其申请公布号为CN120435582A ,申请日期可追溯至2023年10月23日。

该项专利聚焦于马氏体系不锈钢。依据本发明其中一个实例,马氏体系不锈钢铸坯按重量百分比计,各成分具有特定范围:碳(C)含量为0.4 – 0.55%氮(N)含量处于0.01 – 0.1%硅(Si)含量在0.2 – 0.6%之间 ...锰(Mn)含量为0.4 – 0.9%铬(Cr)含量为13.6 – 15.0%(Ni)含量是0.01 – 0.3% ,其余部分为铁(Fe)以及不可避免的杂质。尤为关键的是,在中心偏析部中,面积达到2000μm²以上的一次碳化物,其面积分数需控制在2.5%以下 。这一成分及结构特点,或对马氏体系不锈钢的性能产生重要影响,为该领域的材料制造提供了新的思路与技术方案。
