Cemented carbide coated rollers are significantly harder than steel, typically several to ten times harder. Advantages of carbide-coated rollers: • HV can reach 900–1500, several times higher than steel • Excellent wear resistance • Good corrosion resistance • High surface stability • Long service life

Main Pros of carbide-coated rollers: • High hardness and high wear resistance • Strong corrosion resistance • Good thermal stability • Long service life • High performance-to-cost ratio • Wide range of applications Main Cons of carbide-coated rollers: • Higher cost than ordinary rollers • Coating may peel off • Higher processing difficulty • Lower precision than solid carbide rollers • Not suitable for extreme impact conditions

Many processing scenarios in industrial production place extremely stringent requirements on roller surfaces, which ordinary steel rollers, stainless steel rollers, and chrome-plated rollers often cannot meet. This is the fundamental reason for the emergence of carbide-coated rollers.
