Chrome hollow bars,as kown as hollow chrome rods are specialized components used in various industrial applications. They are known for their durability, corrosion resistance, and aesthetic appeal.
Lightweight Design: The hollow structure significantly reduces weight (by 30%-50% compared to a solid bar of the same diameter).
High Strength & Stiffness: Excellent torsional strength and stiffness, which can be 15%-20% higher than a solid shaft of equivalent weight.
Excellent Accuracy: Hollow chrome bars are produced with tight dimensional tolerances and high straightness (e.g., ≤0.2 mm/m).
Material: Chrome Hollow bars are typically manufactured from high-quality materials such as: C45,C35,304/316/316L stainless steel.
Smooth, Hard Surface: Surface roughness (often Ra ≤ 0.2 µm), facilitates easy cleaning, and enhances wear resistance.
