Benefits of MULTISTEEL’S Hollow Chrome Plated Rods

• High Strength-to-Weight Ratio: These rods provide excellent strength while remaining lightweight, making them ideal for reducing the overall weight of your machinery or equipment.

• Superior Torsion Resistance: Designed to withstand significant torsional forces, they are perfect for applications that demand high torque handling without deformation.

• Excellent Surface Finish: With a surface finish of Ra≤0.4μm, our hollow chrome rods ensure smooth performance and reduce friction, contributing to longer service life and improved efficiency.

• Replacement for Traditional Solid Shafts: These rods can effectively replace solid shafts, offering a more efficient and cost-effective solution for many applications.

• Cost Efficiency: By reducing weight and enhancing performance, MULTISTEEL’s hollow chrome rods help lower system energy consumption and material costs, making them a more economical choice for your business.

FAQs

Q1: How to choose the material?

According to the load type: dynamic impact select SAE4140/42CrMo4; static heavy load select ST52/CK45.

Q2: Can the hollow shaft replace the solid shaft?

It can be replaced in the scene with high torsional strength requirements and weight sensitivity (the working condition parameter calculation verification is required).

Q3: How to control the risk of chromium plating falling off?

Adopt micro-crack chromium process (crack density ≤80/cm²), combined with sandblasting activation treatment of substrate before electroplating.

Q4: Does it support non-standard customization?

Customizable special-shaped cross-section (hexagonal/spline), inner hole step structure, special plating (nickel-based alloy).

Q5: How long is the delivery ?

7-15 days for standard specifications and 20-30 days for customized products.
