Effects of the chemical compositions and the heat treatment on creep strength of a 15 Cr ferritic steel with ferrite matrix were investigated. Creep strength of high chromium steel with What is Creep Strength (Creep Limit)? - MatmatchCreep strength,also known as creep limit,is a measurement of a materials resistance to creep.It is also described as the stress at particular environmental conditions that produces a constant creep rate [2].In other words,creep strength is the maximum stress endured by a material for a specific period of time without extreme deformation.Some results are removed in response to a notice of local law requirement.For more information,please see here.Previous123456NextCreep Strength Assessment of High Chromium Ferritic Creep The existence of the -ferrite is reported to decrease the toughness,ductility,and creep strength of Grade 91 steel plates (Refs.15,16).Coarsened precipitates distribute along the boundaries
