本文报道了日本新日铁公司生产的NF616钢管（推荐的ASME SA213-T92）的化学成份和力学性能及650℃持久强度试验情况。试验结果表明,NF616钢具有良好的韧性,高的高温持久强度,可以代替TP347H制造亚临界和超临界机组锅炉高温过热器,经济效益显著。
This paper reports the chemical composition and mechanical properties of NF616 steel pipe (recommended ASME SA213-T92) manufactured by Nippon Steel Corporation and the test of 650 ℃ long-term strength. The test results show that NF616 steel has good toughness and high high-temperature long-term strength. It can replace TP347H to manufacture high-temperature superheater for sub-critical and supercritical unit boilers and has obvious economic benefits.
