What is Creep Strength (Creep Limit)? - Matmatch

Creep 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.Tensile strength and creep behaviour of austenitic The effect of niobium additions up to 2.36 wt% on the creep behavior of a series of seven extra low carbon 18Cr-12Ni austenitic stainless steels at 700 o C has been investigated.Grain size and hardness measurements,hot tensile tests and constant stress creep tests from 90Study on Tensile Creep Behavior of 12Cr1MoV Alloyorder to reveal the tensile creep behavior of 12Cr1MoV pipeline steel under high-temperature alkali metal salt environment,the tensile creep behavior of 12Cr1MoV alloy under dierent applied load and reaction temperature in high-temperature alkali metal chloride salt environment was studied.
