INFLUENCE OF ENVIRONMENT ON CRACK PROPAGATION AND DELAYED FAILURES IN HIGH-STRENGTH STEELS.
Abstract
Environmentally-induced crack propagation was studied in several classes of high-strength steels with particular emphasis on the influence of aqueous media. Low alloy martensitic steels, 4340 and 300M, were very susceptible to delayed failure in a water or moist air environment while an H-11 die steel was only moderately embrittled. Under the particular test conditions employed the precipitation-hardening and maraging steels were relatively unaffected by aqueous environments. (Author)
