P 122钢具有较高的热稳定性，满足1000MW超超临界机组高温高压蒸汽的要求，但是其可焊性较差。
P122 steel has high thermal stability, can meet the requirements of high temperature and high pressure steam for 1000mw ultra supercritical units, but has poor weldability.
与传统桥梁用钢相比，高性能钢(HPS)在强度、可焊性、断裂韧性、延性和耐候性方面都有很大的改善。
Compared with conventional structural steels used in Bridges, high performance steel (HPS) provides higher strength, improved weld ability, enhanced fracture toughness and weathering characteristics.
