1.2083 ESR - AT A GLANCE
What kind of steel is the 1.2083 ESR?
Tool steel 1.2083 ESR (ESR = Electro-Slag-Refined or Remelted), a corrosion-resistant cold work steel, belonging to the plastic mold steels, with a high chromium content it has very good corrosion resistance (in its hardened condition) and good wear resistance.
The X40Cr14 ESR can easily be machined and is, due to the purity of the ESR material, highly polishable. With high compression strength and high wear resistance, the low-distortion through-hardener is suitable for injection molds of all types where good resistance to chemical aggressive molding compounds are required.
The remelting process provides this tool steel with a very low inclusion content, which makes it possible to provide a mirror finish when used for instance for lens molds or photoetching.
Properties
Steel grade 1.2083 ESR is a steel grade with good corrosion resistance, hardness and toughness that is easy to machine and responds well to heat treatment. This makes it ideal for a wide range of applications, such as industrial tools and medical instruments. Highly polished, it even finds its way into our households, for example for cutlery.
- High hardenabilty
- Good wear resistance
- Good machinability
- EDM machinable
- Etchable
- Excellent polishability
- Low distortion through-hardener
- Nitriding is not commonly done
- Conditionally acid resistant
Applications
The 1.2083 ESR can be used for applications that need corrosion or staining resistance, e.g., for molding of corrosive materials like PVC, acetates, for molds subjected to humid working conditions as well as surgical and dental instruments and tools.
Wear resistance, e.g., for molding abrasive materials and high surface finish, e.g., for the production of optical parts, such as lenses, for cameras and sunglasses, and for medical containers.
