The steel is said to be ideal for manufacturing die cast moulds, thanks to improved temperature stability and greater toughness. "The inevitable thermal-shock cracks will cause moulds to fail sooner or later. At some point, the cracks merge, causing chips, which then affects the surface of the part being cast. Our new hot-working steel significantly delays this,” says Michael Bauer, technical customer service advisor.

When manufacturing die cast components, a molten light metal is filled in a pre-tempered mould. The process happens very quickly and under high pressure ranging from 150 to 1000 bar. The mould is thus exposed to both mechanical as well as thermal cyclic load and can only cope in the long term if it is made from a hot-working steel that provides an ideal combination of high temperature resistance, toughness and thermal conductivity, Bauer explains.
