420 mod. Steel

420 mod. Steel

Steel name: 420 mod.
Diagram No.: 1052
AISI/SAE designation: 420 modified
Chemical composition in weight %: Cr-Ni-Mo-V alloyed steel
Steel group: Plastic mould steels
Properties: No data
Applications: Although steel is recommended for all types of moulds, its special properties make it particularly suitable for moulds with the following demands: Corrosion/staining resistance, i.e. for moulding of corrosive materials, e.g. PVC, acetates, and for moulds subjected to humid working/ storage conditions. High surface finish, i.e. for the production of optical parts, such as camera and sunglass lenses, and for medical components, e.g. syringes, analysis vials etc..Toughness/ductility, i.e. for complex moulds. Outstanding through-hardening characteristics i.e. high-hardenability, important for larger moulds.
Reference: Not shown in this demo version.
