摘要：
A heat resisting alloy of Fe--Cr--Ni type for exhaust valves, knit meshes for the catalyzer and the like which is low in price and excellent in high temperature properties, which consists essentially by weight percentage of C:0.01.about.0.10%, S:.ltoreq.2.0%, Mn .ltoreq.2.0%, Cr:14.about.18%, Nb+Ta:0.5.about.1.5%, Ti:2.0.about.3.0%, Al:0.8.about.1.5%, Ni:30.about.35%,B:0.001.about.0.01%, Ca+Mg:0.001.about.0.01%,Cu.ltoreq.0.5%, P.ltoreq.0.02%, S.ltoreq.0.01%, O.ltoreq.0.01%, N.ltoreq.0.01%, and the balance of Fe, additionally the total atomic percentage of Al, Ti, Nb and Ta:5.0.about.7.0%, and atomic percentage ratio of Ti/Al:1.0.about.1.5, and M-value calculated from the following equation .ltoreq.0.95; M=�0.717 Ni(at. %)+0.858 Fe(at. %)+1.142 Cr(at. %)+1.90 Al(at. %)+2.271 Ti(at. %)+2.117 Nb(at. %)+2.224 Ta(at. %)+1.001 Mn(at. %)+1.90 Si(at. %)!/100.
