Abstract

A new corrosion resistant Ni-Cr-Mo-Ta alloy, MAT 21 has been developed. This new alloy, which is composed of 19wt% chromium, 19wt% molybdenum, 1.8wt% tantalum and balance nickel, shows excellent corrosion resistance to pitting and crevice corrosion as well as to general corrosion compared to the existing Ni-Cr-Mo alloys.
