Elevated Temperature Properties of Nitrogen-Containing Type 304L Austenitic Stainless Steel

Source

Experimental heats of Type 304L steel, compositionally balanced to be wholly austenitic, were prepared to determine the influence of nitrogen on elevated temperature properties of this steel. Nitrogen is shown to increase the 1200 F (649 C) and 1350 F (732 C) yield strength slightly and to increase markedly the creep and rupture strength at 1200 F (649 C). The effect of nitrogen on creep and rupture strengths at 1350 F (732 C) and 1500 F (816 C), however, is less pronounced. A beneficial effect of nitrogen on creep and rupture properties at 1200 F (649 C) is attainable from a considerable range of heat treatments and grain sizes.
