摘要
介绍了Sanicro25奥氏体耐热钢的力学性能、持久强度、抗氧化腐蚀性能,以及常用物理性能,并与Super304H和HR3C钢进行了比较。结果表明:该钢可用于高效超超临界火电机组蒸汽温度为620℃的受热面的钢管。
An introduction is being presented to the mechanical property, creep rupture strength, anti- oxidation and anti-corrosion property, as well as to typical physical properties of the austenitic heat-resistant steel Sanicro25, which are further compared with the steels super304H and HR3C. Results show the steel can be used as the pipe of heating surfaces with steam temperature at 620 ℃ for high-efficient ultra- supercritical thermal power units.
