摘要
综述了低预热焊接的高强度舰船结构钢种的研究现状和发展途径。指出其发展途径主要是改进现役钢种、开发沉淀硬化型舰船结构钢、研究超低碳贝氏体舰船结构钢及采用新的生产工艺。
The present status and the ways to develop marine high strength structural steels weldable at lower preheating temperature are given, and it is pointed that the main ways to develop the steels may include the improvement of the existing steels, developments of precipitation hardening steels and ultra-low carbon bainitic steels as well as utilization of new production processings.
