Abstract
New grades of heat-resistant structural steels with an increased content of chromium (9-12 %), intended for manufacture of parts operating at supercritical (T > 560-600 ^oC) and ultra-supercritical (T ~ 620-630 ^oC) steam parameters, are considered. The effect of alloying on phase composition, corrosion resistance, ageing processes, long-time strength and weldability of steels is analysed.
Keywords: heat-resistant steels, complex alloying, supercritical parameters, corrosion resistance, structure, ageing, dispersed phases, long-time strength, weldability
