Abstract
An amorphous metal alloy composition exhibiting corrosion resistance in acidic environments of the formula: EQU Cr.sub.a M.sub.b B.sub.c C.sub.d R.sub.e wherein PA0 M is at least one metal selected from the group consisting of Mo, W, Nb and Ta; PA0 R is at least one element selected from the group consisting of N, P, As, S and Se; and wherein PA0 a ranges from about greater than 0.4 to about 0.6; PA0 b ranges from about 0.15 to about less than 0.4; and PA0 c ranges from zero to about 0.16. PA0 d ranges from zero to about 0.2; and PA0 e ranges from zero to about 0.3; with the proviso that the sum of (c+d+e) ranges from about 0.04 to about 0.35.
