Materials Delaying thermal cracks reduces maintenance costs
Germany - Toughness and resistance to thermal shock are among the most important features of DEW's new hot-working steel for Nemak, an international manufacturer of aluminium die-cast parts. Nemak’s Polish subsidiary is currently testing the steel.
Thanks to the improved properties of Thermodur E 40 K Superclean, Nemak, an international manufacturer of aluminium die-cast parts, is particularly interested in Deutsche Edelstahlwerke’s (DEW) new hot-working steel. According to DEW, the German subsidiary of the Schmolz + Bickenbach Group, the new material introduced last year immediately attracted a lot of attention because it delays the formation of hot cracks and thereby significantly increases the life of the tool compared to conventional hot-working steel.
Nemak’s Polish subsidiary is currently testing whether the steel can be used as material for the inserts in the dies used for manufacturing 4-cylinder engine blocks. A single rectangular or cube-shaped insert weighs around 300 kg. “The material's toughness and resistance to thermal shock are most important to us because both of these properties have a decisive impact on the rate at which hot cracking occurs,” explains the management of Nemak Poland.
