- Information
Extreme Wear Resistance: The high tungsten and carbon content of Cobalt Alloy 20 (56-60 HRC) provides superior protection against abrasive wear from tinplate and aluminum cans.
Superior Red Hardness: Maintains exceptional mechanical properties and hardness at high local frictional temperatures (up to 400°C).
Food-Grade Corrosion Resistance: Excellent resistance to organic acids, brines, and harsh CIP (Clean-in-Place) chemicals, ensuring zero contamination.
Anti-Galling & Mirror Finish: Precision-ground grooves prevent "Angel Hair" (metal slivers), ensuring smooth sealing and reduced scrap rates.
Extended Service Life: Outlasts standard stainless steel and D2 tool steel rollers by 5 to 10 times, resulting in significantly lower Total Cost of Ownership (TCO).
