Formadur 320/320 Superclean Steel

Formadur 320/320 Superclean Steel

Steel name: Formadur 320/320 Superclean
Diagram No.: 2360
Chemical composition in weight %: 0.34% C, 0.80% Mn, 1.70% Cr, 0.40% Mo, 0.50% Ni
Steel group: Plastic mould steels
Properties: Heat-treated mould steel with improved quenching and tempering properties in comparison to 1.2738. Good machinability, polishable, weldable and can easily be textured. Formadur 320 is either available at a hardness of 280 – 325 HB or 310 – 355 HB. This grade offers substantial improvements, especially for building larger and complex moulds. Specific modifications of the grade's components as well as additional smelting and secondary metallurgy ensure Formadur 320's outstanding properties. We recommend the use of Formadur 320 Superclean (ESR) for the highest demands.
Applications: Formadur 320 is highly suitable for large-format plastic injection and extrusion moulds with deep engraving and high demands on core strength, such as with bumpers, tailgates, fenders, spoilers, instrument panels and TV housings to name a few. At a supplied hardness of 310 – 355 HB, maximum wear resistance is guaranteed.
