MAX1 (0.3C, 4Cr, 0.6Mo, 1W, 0.4V, 2Co) is a new hot-work die steel alloy-designed to retain the least of undisolved carbides in quenched condition and to obtain secondary precipitations well enough.
This steel proves that it has excellent ductility together with high strength and that it satisfies various demands for heavy-duty hot-work dies as follows:
easy austenitizing as conventional steels,
negligible distortion induced by heat treatment,
high fatigue-strength at elevated temperatures,
skin-deep heat-checking cracks,
good wear resistance,
small corrosion loss in molten Al,
adaptability to gas nitriding.
