Ferrium M54 Steel

Abstract

Bare and Zn-14% Ni alloy coated Ferrium M54 steels were studied to clarify their mechanical, fatigue, and stress corrosion cracking (SCC) properties. Compared to the currently available high strength and high toughness steel, AerMet 100, this steel has much greater SCC resistance, but similar mechanical properties and susceptibility to corrosion fatigue. The Zn-14% Ni alloy coating appears to provide the steel some protection against hydrogen embrittlement/SCC and corrosion fatigue in aqueous 3.5% NaCl solution of pH 7.3. The fatigue crack growth mechanisms of the bare and coated steels are striation formation in air, and a combination of striation formation and intergranular cracking in aqueous 3.5% NaCl solution.
