Erosion Resistance

Riley Power conducted laboratory testing, following ASTM G73 standards, on low swirl coal spreaders to determine the best erosion protection from fine-grit black beauty coal slag. Testing was conducted at a 90 degree impingement angle with a particle velocity of 240 ft/sec for 30 minutes. 

Kennametal's WC 219 cladding provided top wear protection while retaining critical component geometries. Kennametal increased Riley Power's low swirl coal spreader life from 1-2 years to 3-4 years.
