【Abstract】 By means of Laves phase strengthening,dispersion strengthening,solid solution strengthening,carbide strengthening,dislocation strengthening and other comprehensive strengthening mechanisms,the comprehensive properties of ordinary heat-resistant steel can be further improved to meet the material standards of ultra-supercritical thermal power units and ensure the safety of equipment operation. This paper analyzes development status of ferritic heat-resistant stainless steels at home and abroa,puts forward some policy suggestions for the development of heat-resistant stainless steel industry in Shanxi Province.更多还原
