Description	Maraging steels based on iron–nickel martensite constitute a very important family of high-strength steels, which distinguishes itself by demonstrating an unparalleled combination of excellent fabricability and high strength and fracture toughness after heat treatment. Heat treatment of these steels has now been perfected to ensure consistently high levels of strength, ductility, and toughness in a variety of product shapes and sizes. Cobalt-free variants have been commercialized as part of efforts to save production costs. Further knowledge has been generated on 18% Ni maraging steels regarding phases precipitating during aging, thermal embrittlement, thermal cycling, and austenite reversion/retention and their effect on mechanical properties. Filler wires of optimized chemical composition have been developed to yield efficiencies of ~90% in fusion-welded joints of maraging steel. Environmental degradation of maraging steel is a matter of serious concern and considerable progress has been made to generate further understanding in this area. This entry reviews the subject with particular reference to the progress made over the last two decades. Book Name: Encyclopedia of Iron, Steel, and Their Alloys
