An experimental columbium-tantalum ferro-alloy (40Cb-20Ta) was used to make laboratory heats of low-carbon N-155 and an N-155 type alloy (20Cr-20Ni-20Co+2Cb). The amount of columbium in the alloys was reduced so as to keep the atomic percent of columbium plus tantalum equal to the normal atomic percent of columbium.
