Heat Treatment & Vacuum Hardening
In-house vacuum hardening for D2, M2, HSS and A2 blade substrates. HRC 58–64 range, distortion-controlled.
- Vacuum quench — minimal distortion on long thin blades
- D2 to HRC 58–60 routinely; M2 / HSS to HRC 62–64
- Cryo-treat option for high-cycle slitter blades
- Hardness checked Rockwell-C on every batch, certificate available
Heat treatment is the difference between a blade that lasts 3000 pouches and one that fails at 300. Our vacuum hardening line minimises distortion on long, thin blade substrates so we can grind a true edge afterwards. Hardness is checked on Rockwell-C and printed on the batch report.
