A New High Performance, Cost Effective, Carburizing Grade Alloy Steel 810424

A 1.8 Ni-0.60 Cr-0.12 V alloy steel has been developed for use in carburizing applications. Hardenability, strength, toughness, and fatigue tests have been conducted on this material. Comparisons were made with the properties of several standard nickel alloy steels including 4620, 4320, 3310, and 4815 which show that the Ni-Cr-V alloy performs at least as well as the 1.8% Ni grades (4620, 4320) and approaches, and in some instances equals or exceeds, the 3.5% Ni grades (3310, 4815). The Ni-Cr-V alloy, can provide a cost effective substitute for these more costly high nickel grades.
