Kennametal presents wear protection for road milling machine

Road building is among the world’s most extreme jobs, one that chews up wear components regularly, slowing important projects and raising the costs of doing business. Major road construction contractors are well aware of Kennametal technology and leadership in conicals, blocks, and drums. That same Kennametal leadership and service is now available in advanced wear protection for replacement skis for road milling machines.

Two choices are available: Super C? or KenCast? skis. “Super C is our premium chromium carbide overlay for applications requiring extreme abrasion resistance with moderate impact,” says Aniruddha (Ani) Marathe, Kennametal product manager. “Super C is highly rated by industry for applications requiring significant abrasion resistance with moderate impact, good formability and weldability.”

Kennametal’s proprietary welding process produces a high volume of hexagonal chromium carbides (M7C3), he explains, which provide higher wear resistance in sliding abrasive applications. “Our unique blend of chemistry and processing provides significantly higher wear resistance, leading up to three times wear-life improvement compared to other after-market products, depending on operating conditions.”

For even higher levels of wear protection, Kennametal’s KenCast? is a composite material with the wear resistance of tungsten carbide and the toughness and weldability of steel. KenCast provides up to five to seven times improvement in wear life compared to steel wear solutions.

“In either choice, Kennametal skis have industry-leading wear performance, offering more options depending on conditions and providing the best value for road milling contractors,” Marathe adds.
