Sub-Zero Treatment (up to -70°C)

What it does: After hardening, steel may retain austenite that hasn’t transformed into martensite. Sub-zero treatment involves cooling parts to -70°C to complete this transformation, increasing dimensional stability and wear resistance.

Best suited for:

  • High-precision tools, cutting dies, aerospace components
  • Parts with tight dimensional tolerances and high wear demands

Ideal if you’re looking for:

  • Enhanced dimensional stability during long-term service
  • Maximum wear resistance and transformation of retained austenite
