Where it wins and where it loses

Choose it when

  • Your blades fail by wearing out, not by chipping
  • You need HRC 54–58 and want it written on the quote
  • The application fits food processing, wash-down, hygiene-critical

Look elsewhere when

  • The blade is chipping or cracking — go tougher, not harder
  • You need corrosion resistance — use 440C stainless
  • Line speed is very high — HSS or carbide holds hardness better

How we work it

440C Stainless is vacuum hardened and tempered in-house, then ground on CNC and surface grinders. Hardness is checked on every piece before it is packed. If your drawing calls for a different hardness window, we will tell you whether it is achievable and what it costs in toughness.
