ASP® 2042
ASP® 2042 is a Powder Metallurgy High-Speed Steel grade with high hardness and high toughness. It is an upgraded material in particular in applications where standard M42 is traditionally used e.g. for laser-welded bi-metal saws with improve saw performance, thanks to its higher hardness and toughness. It is also recommended for high performance components.
