Materials used for this blade
Cr12MoV
HRC 58–62 · High
Widely used, well understood grade. Good balance of cost and life.
Read the full grade guideSKD-11 (D2)
HRC 60–64 · Very high
Longer life than Cr12MoV at higher cost. The default upgrade.
Read the full grade guideHSS M2 / M42
HRC 62–66 · Very high
M42 (cobalt) for heat resistance at very high line speeds.
Read the full grade guide440C Stainless
HRC 54–58 · Medium-high
Rust-free. Required wherever blades see water and cleaning.

On packaging lines the biggest cause is not abrasive material but heat and fatigue. A dull blade raises sealing temperature, which softens the tooth tips, which dulls them faster. Using a slightly harder grade (SKD-11 at HRC 60–62 instead of carbon steel) and checking the anvil clearance usually doubles the service interval.
Yes — send one used blade, or a photo next to a ruler plus the tooth count and pitch. We will confirm the profile drawing before production. Tooth geometry is the one thing buyers most often get wrong when sourcing, so we always verify it in writing first.
We supply 440C stainless blades for food lines. One honest point: food-contact compliance (EU 1935/2004, FDA 21 CFR or your local rule) is validated at your plant under your HACCP plan — we make the blade right, you validate the process.
Repeat orders of an existing profile have a MOQ of 5 pieces, and because the profile is already programmed, lead time is shorter than a first order. For packaging plants we recommend holding 2–3 sets in stock — a stopped line costs far more than the knives.
