Hot work tool steel; good hardenability.Uniform hardness over section also at great dimensions. Resistance under impact loadings. Very good strength and toughness. Good tempering resistance and dimensional stability.
Enduse = Forging tools,dies of all sorts,shapes and sizes,hot forging and pressing tools for steel and metal. Moulds, bushings, piercers etc.
