Description

Long-term creep strength of material in the low-stress regime below elastic limit is difficult to predict by an extrapolation of short-term creep strength in the high-stress regime above elastic limit. Long-term creep strength of fully annealed ferrite-pearlite microstructure of low alloy Cr-Mo steel is higher than that of martensite and bainite microstructures. It is explained by lower dislocation density of fully annealed microstructure. According to the above concept, creep strength of high chromium steel with ferrite matrix is investigated. Creep rupture life of 15Cr-Mo-W-Co steel with ferrite matrix which is longer than that of ASME Grade 92 steel is obtained at 650 oC by controlling the chemical composition and heat treatment condition.
