Product Introduction

Our QPQ-treated piston rods are available in multiple materials including C45E, 40Cr4, 42CrMo4 and 25Mn, with customizable sizes of 20mm?500mm in diameter and 200mm?15000mm in length. Adopting professional QPQ salt bath composite treatment, the compound layer thickness reaches 0.015?0.02mm with dense and stable structure. After precision polishing, the surface roughness achieves Ra 0.4, ensuring low friction and reliable sealing performance. The surface hardness ranges from 500 to 600 HV for excellent wear resistance. With superior anti-corrosion property up to 300-hour NSS test, the rod is ideal for humid, outdoor and harsh working conditions, serving as an eco-friendly upgrade alternative to traditional chrome plating.
