DIN 1.2085

Tempered, tool steel with higher sulfur content for better machinability

DIN 1.2085 is a hardened, tool steel with a high chromium content (approx. 13%) and the addition of sulphur to improve machinability. Compared to the similar steel 1.2083, it has poorer polishability, but is more suitable for the production of large or less demanding moulds, where corrosion resistance and good machinability are required. It is supplied in the hardened state 280-325 HB.


Alternative designation: X33CrS16
Type: Tempered, sulfur-added tool steel

Heat treatment:

  • Preheat: 600–850 °C

  • Quenching: 1000–1040 °C (oil or air)

  • Tempering: 180–250 °C depending on the required hardness

  • Nitriding or coating option for surface improvement

Features:

  • Good corrosion resistance due to high Cr content

  • Significantly better machinability than 1.2083 (thanks to sulfur)

  • Lower polishability – unsuitable for optical forms

  • Hardness after hardening up to 48–52 HRC

  • Good dimensional stability during machining

  • Not suitable for high-gloss polishing or etching

  • Supplied in a refined condition

Use:

  • Plastic molds with lower surface finish requirements

  • Dies

  • Tools and parts exposed to humid or corrosive, abrasive environments

  • Larger shaped parts where ease of machining is a priority

  • Moulds for technical plastics, containers, packaging, especially their frames

  • Applications where a combination of corrosion resistance and ease of fabrication is required
