Chromed and honed tube for concrete delivery cylinder Introduction

Chromed and honed tube for concrete delivery cylinder is widely used for oncrete delivery cylinder which is inside chrome plated. The chromium-plated layer has a high hardness, and the hardness can vary in a wide range of 400 ~ 1200HV according to the composition and process conditions. Chromium plating layer has good heat resistance, heat under 500 ℃, its gloss, hardness, no obvious changes, temperature higher than 500 ℃ oxidation discoloration, greater than 700 ℃ to reduce hardness. The chromium-plated layer has a low friction coefficient, especially the dry friction coefficient, which is the lowest among all metals. So the chromium plating has good wear resistance.
