近日，该集团特钢事业部在高氮无磁不锈钢研发领域取得重大突破，成功开发出氮含量超0.85%的高氮无磁奥氏体不锈钢产品，填补了国内常压熔炼高氮不锈钢领域的技术空白。
北重集团特钢事业部通过与高校及科研院所展开深度技术合作，联合攻克了常压下高氮含量合金工程化冶炼这一世界性技术瓶颈。此技术以氮元素替代稀缺贵重的镍元素，在无需高压设备的情况下，实现了氮含量0.85%以上的高氮无磁不锈钢的稳定生产。该生产过程安全性更高，且具备工业化量产的条件。
此次研发的高氮无磁不锈钢展现出优异的综合性能。其强度远超传统奥氏体不锈钢，耐腐蚀性尤为突出，在海水等复杂环境中表现稳定。同时，在冷加工变形后，强度大幅提升的同时仍能保持良好韧性。该材料可制备管、板、棒材，ȃ..
