The influence of microstructure on the creep properties of 441 ferritic stainless steel

The objectives of this report were to determine the influence of microstructure on the creep properties of 441 stainless steel. Of particular interest was the effect of grain size and of the niobium content. A further requirement of this investigation was to design and manufacture two lever-arm type, constant load creep rigs in response to the need for a high quality creep test facility. These rigs were to be used to satisfy the initial objective and to evaluate an industry benchmark test used for determining the creep resistance of a particular alloy, known as the sag test.
