在列举了有关Super30 4H材料的性能数据 ,如Super30 4H的化学成分、增强机理、机械性能、蠕变断裂性能、老化性能、抗蒸汽氧化性能及焊接、弯曲等加工性能和电厂实际使用业绩后 ,说明了Super30 4H可用作大容量、高参数、超超临界机组的材料。该材料在用于上述机组时 ,部件壁厚减少、部件所用钢材量减少、结构承重和热应力减少、制造成本和施工难度减少、具有很好的经济性。
After citing performance data on the Super30 4H material, such as the chemical composition, strengthening mechanism, mechanical properties, creep rupture properties, aging properties, resistance to steam oxidation and processing properties such as welding and bending of the Super30 4H and the actual use of the power plant, Description Super30 4H can be used as a large capacity, high parameter, ultra-supercritical unit of material. When the material is used in the above units, the wall thickness of components is reduced, the amount of steel used for components is reduced, the structural load-bearing and thermal stress are reduced, the manufacturing cost and construction difficulty are reduced, and the economy is good.
