Brief Introduction
Metal (Gcr15,100Cr6,52100,SUJ2) steel balls, also called bearing steel balls,High precision chrome (high carbon) steel balls contain chromium.They offer superior wear resistance, high hardness and high load bearing capacity as a result of through-hardening.
Grade 25 chrome steel bearing balls are widely used in precision ball bearings as well as most aerospace, Transportation and industrial applications. Chromium (CR) has a tendency to increase hardness, toughness and wear resistance of steel. Chrome steel is a chrome Alloy carbon steel, not a chrome plated steel.The finest quality chrome steel produced in accordance with the highest industry standards. Modern furnaces with precisely controlled atmospheres and temperatures are used for heat treating to assure uniform hardness and proper microstructure for each Stainless steel ball. Throughout the manufacturing process, statistical process control assures tolerance accuracy, fine surface finish and consistent high quality.
Chrome balls are manufactured from the highest quality chrome alloy steel and through-hardened for maximum strength and service life. Applications that are ideal for chrome balls include tumbling media, ball bearings,Wind Turbine Bearing, linear motion components.most widely used in various industires.
