Product Description

Introduce

The hard chromium plated rod is a steel rod made of C1045 hard chromium plated surface. Under the supervision of experienced engineers, bars undergo strict processes such as fuzzing, straightening, grinding, polishing, hard chromium plating, and precision machining. Hard chrome plated piston rods are widely used in hydraulic cylinders, pneumatic cylinders, printing machinery, textile machinery, engineering machinery, woodworking machinery, and so on. Our products are highly praised by customers for their corrosion resistance, sturdy structure, high durability, high tensile strength, and mirror surface characteristics
What can we offer:
1. We can provide a full range of hard chromium plated rods with a diameter of 3mm -120mm and a maximum length of 8000mm.
2. We can provide customized materials including GCr15/SUJ2, 42CrMo/4140.
3. When you have special requirements for mechanical processing or turning, such as tapping, drilling, tapping, milling keys, etc., we can perform turning for you. We have multiple high-precision milling machines, drilling machines, and 14 CNC lathes. Our advanced equipment, skilled technical workers, scientific testing instruments, and strict quality control all ensure the accuracy of our products. Our service center is always at your service, processing shafts according to your requirements or drawings. You will be satisfied with our service.
