豪森钢公司开发了一种含镍约5％的焊接结构钢,这种钢可以在温度低达-200℃的情况下使用。因为这种由一次正火处理得到的热轧钢,通常具有良好的低温性能,因而在生产过程和成本两个方面都超过了闻名世界的含镍9％的X8Ni9钢。开发这种钢的原因是:消费国家在能源方面对天然气的不断增长需要,以及运输液化天然气所需要的贮存容器和油船越来越多。与液化灭然气相比,将来液化气的海上运输要成为一个问 Howon Steel has developed a welded structural steel containing about 5% nickel, which can be used at temperatures as low as -200 ° C. Because this hot-rolled steel, which is obtained from one normalizing treatment, usually has good low-temperature properties, it exceeds the world-famous 9% X8Ni9 steel containing nickel in terms of production process and cost. The reason for the development of this steel is that there is an increasing demand by consumers in the area of ​​energy for natural gas and the growing need for storage containers and tankers for the transport of liquefied natural gas. In the future, liquefied gas will be transported by sea as liquefied gas
