Fourteen candidate wire alloys were evaluated against the standard deck-pendant wire material, (extra-improved plow steel, EIPS), for their tension, torsion, impact/abrasion resistance, and fatigue-performance properties - as well as their resistance under impact/abrasion conditions. Cost considerations for the new materials were also included in the evaluation criteria. None of the four better-performing candidate alloys showed transformations after impact/abrasion, while the EIPS showed a definite transformation to what was concluded to be untempered martensite. The effects of impact/abrasion (and presumably the transformation) caused the EIPS to lose 81 percent of its unabraded fatigue life. All of the better-performing candidate alloys suffered some lesser reduction in fatigue life. All of the better-performing candidate alloys suffered some lesser reduction, in fatigue life. The two candidate alloys that performed the best were MP35N and Elgiloy. However, their rapidly escalating and current high costs are believed to be too high to justify their promise of improved deck-pendant reliability and life. Therefore, the two lower-cost alloys, Inconel 718 and 11R51SH, were recommended for experimental rope manufacture and evaluation. (DePo)
