Material of S45C Hard Chrome Plated Piston Rod : JIS S45C / DIN CK45 / SAE 1045 and JIS S55C. By precision cold drawing, the tensile strength is higher. After harden chrome plating, the chrome shaft obtains good corrosion resistance, great abrasion resistance, uniformity of hardness. Piston Rod can further go through other additional processing like lathing, milling and drilling, etc. Suitable for piston rod, hydraulic cylinder rod, pneumatic cylinder shaft, punching machine, pressing machine, mechanical guide rod, mechanical column bar, solid bar, crane, plastic injection machine, sealing machine, packaging machinery, and other automation machinery.
