Our chrome plated shafts gained good reputation for features as bleow.
a. The hard chromed surface confers the important properties of corrosion resistance and wear resistance; it is also very smooth and therefore has a low coefficient of friction. Not least of all, it has an attractive and durable decorative appearance.
b. Carbon steel balances durability, hardness, and wear resistance using formability, weldability, and durability;
c. High precision tolerances, which ensures when used to make hydraulic piston shafts, it can fit the cylinder precisely.
d. High performance of strength: The yield strength of chrome plated shafts can be 75000 psi up to 100000 psi, depends on the material and heat treatment method.
e. Good Hardness: the surface hardness attaining HV850 minimal and upward, which not only help improve wear resistance but also help extend the life span of these chrome plated shafting, thereby helping the consumer save the cost.
f. Excellent smooth surface: The surface roughness of our factory’s hard chrome plated shafting is around Ra0.2μm(8 Ra), max. Ra0.4μm (16 Ra).
All the chrome plated shafts will be oiled by the anti-rust oil before delivery. And to protect the outer surface of the chroming of piston rods, we will use cardboard (paper pipe) to pack each rod, and then pack with seaworthy package such as wooden cases or rope wraps.
Application of Chrome Plated Shafts
Chrome plated steel rods are widely used in many differet industries, such as:
- Hydraulic shafting,
- Pneumatic piston rods,
- Pump shafting
- Shaft for machinery, such as Textile machinery center shaft, Transport machinery center shaft, etc.
- Rollers for machines, such as packing machine rollers, printing machine rollers and so on.
Besides soild steel rods, Chrome plated shafts also can be made of chrome plated hollow bar.
