Atomfair 18Ni300 Maraging Steel Powder
18Ni300 is an ultra-low carbon Fe-Ni alloy, based on carbon-free or micro-carbon martensite. It achieves secondary phase strengthening via precipitation of alloy compounds from Mo, Co, Ti, Al during aging, with ultra-high strength and excellent toughness. Suitable for SLM, used in mold manufacturing, aerospace, precision cutting tools.
