1.2767 ESR - AT A GLANCE
What kind of steel is the 1.2767 ESR?
1.2767 ESR (ESR = Electro-Slag-Refined or Remelted) has, with the addition of nickel, the ability, even for large cross sections, to be trough-hardened very well. With its high compressive strength this tool steel grade lend itself for stamping or demanding coining tools.
It has high resistance to bending which is an advantage when used for bending inserts. Tool steel 1.2767 ESR is exceptionally suitable to be polished to a mirror finish and therefore is a fitting choice to process plastics that require a high surface finish.
Due to its nickel content, 1.2767 ESR not only has a high hardenability but also a high toughness. The electro-slag remelt process ensures a high level of purity and a homogeneous structure.
Properties
The 1.2767 has a unique combination of wear resistance, toughness and hardness. Those properties make it a great choice for applications which are demanding and use high stress components. To avoid unwanted changes or to reduce risks it is essential to weigh use, properties needed, appropriate heat treatment as well as maintenance carefully.
