Simple Determination of Creep Limit for Mild Steel

Abstract

In this paper, creep characteristics of mild steel which are to be determined by long term creep tests are interrelated with that of short term creep tests. It leads to the prediction of long term creep limit from the data of short term creep tests together with that of single long term creep test datum. The prediction is demonstrated by examples. Temperature dependence of creep characteristics of the material is also discussed, and a proposition is made on the estimation of creep limit at arbitrary temperatures from the data of creep tests conducted at a reference temperature.
