Metallurgical and Stress State Factors Which Affect the Creep and Fracture Behavior of 9% Cr Steels

<div>Creep ductility (reduction of area) for Grade 91 steel supplied by one manufacturer [<a href="/journals/amse/2018/6789563/#B40">40</a>]. A dashed line is shown at 70% for the reduction of area since this was an acceptance criterion proposed by ORNL in the development of Grade 91 steel [<a href="/journals/amse/2018/6789563/#B20">20</a>].</div>
