摘要： An Fe-Cr alloy having an excellent workability over a wide range of the Cr content (e.g. 3-60 wt.%) by limiting the total content of C, N, O, P and S to 100 ppm or less. Fe-Cr alloys with various characteristics can be obtained by adding various combinations of the following element groups (1 to 4) to the Fe-Cr alloy of the basic composition: (1) a group consisting of Ni, Co and Cu with a total content of the elements in a specified range, contributing to an increase in acid resistance; (2) a group consisting of Al, Si and Mn and/or a group consisting of Ca, Mg and REM each with a total content of the elements in a specified range, contributing to an increase in oxidation resistance; (3) a group consisting of Ti, Nb, Zr, V, Ta, W and B with a total content of the elements in a specified range, contributing to an increase in high-temperature strength, and (4) a group consisting of Mo alone with a content thereof in a specified range, contributing to an increase in pitting resistance.
