Plastic & Rubber

Plastic & rubber production parts are subjected to a combination of corrosion and abrasive wear that can quickly eat away ordinary materials. Stellite® alloys help to reduce metal to metal wear and improve performance under poor lubrication conditions, tight running clearances and corrosive environments. Kennametal Stellite™ manufactures cast components, hardfacing consumables, hardfacing equipment and carries out hardfacing of new as well as worn out components for plastic extrusion. 

Alloys commonly used in the plastics & rubber industry are Stellite® 1, Stellite® 6 or Deloro® 60. For this industry the alloys are typically supplied in Cast Rod, MIG Wire or Powder form.
