DIN 1.2083 ESR

High-purity stainless tool steel for high-demand molds

DIN 1.2083 ESR is an electroslag remelted version of 1.2083 steel, which offers higher purity, finer structure and better polishability than the standard version. Due to the high chromium content (approx. 13%), it has excellent resistance to corrosion, wear and chemical influences. It is ideal for plastic molds with high surface requirements, optical parts or where there is a risk of corrosion.


Alternative designation: X40Cr14 ESR
Type: Stainless steel (ESR – Electroslag Remelting)

Heat treatment:

  • Preheat: 600–850 °C

  • Quenching: 1000–1050 °C (air or oil)

  • Tempering: 150–250 °C depending on the required hardness

  • Possible nitriding or PVD coating to improve surface properties

Forged blocks, tempered 280-325 HB
