Phase transformations and magnetic properties in cobalt free and low cobalt, chromium containing maraging steels have been investigated. The aging response and microstructural developments have been monitored in the temperature range between 450 and 700°C. The hardening, following aging, occurred as a result of the formation of Ni3 Ti and Fe7 Mo6 phases. The magnetic properties of these alloys were also determined in specimens aged between 400 and 750°C. The coercive force and saturation magnetisation have been related to the reverted austenite content.
