EXCLUSIVE HIGH CARBON, NO-STAIN STEEL
Stainless steel for the cutlery industry has been perfected by ZWILLING J.A. HENCKELS. Resistance to corrosion and hardness are determined by the content of chromium and carbon in the raw material and its subsequent heat treatment. ZWILLING J.A. HENCKELS undertook intensive research to find the optimum alloy resulting in a "special formula" that is still being used today in TWIN® cutlery assortments.
