Investigation on Creep Behavior of Grade 91 Heat-Resistant Steel at 923K

摘要：

　　Creep deformation behavior of SA387Gr91Cl2 heat-resistant steel used for steam cooler has been investigated.Creep tests were carried out using flat creep specimens machined from the normalized and tempered plate at 973K with stresses of 100,125 and 150MPa.The minimum creep rate and rupture time dependence on applied stress was analyzed.The analysis showed that the heat-resistant steel obey Monkman-Grant and modified Monkman-Grant relationships.
