cold-formed or cold finished nickel - cobalt alloy with hoeg haallfasthet at foerhoejd temperature

摘要

A work hardened nickel-cobalt alloy having high strength and ductility at temperatures of about 1300 DEG F is provided consisting essentially by weight of about 0.05% max carbon, about 20%-40% cobalt, about 6%-11% molybdenum, about 15%-23% chromium, about 1.0% max iron, about 0.0005%-0.020% boron, about 0%-4% titanium, about 0%-2% columbium and the balance nickel, the alloy having been cold worked at a temperature below the HCP-FCC phase transformation zone to a reduction in cross-section between 5% and 50%.
