Product Description
Distributors, stockists, and contractors choose this product due to several key benefits:
Induction hardening increases hardness up to HRC 50-62, enhancing wear resistance.
Chrome plating provides a smooth, rust-resistant finish suitable for outdoor and marine environments.
Induction hardening improves fatigue life in dynamic load conditions.
Precision grinding ensures tight tolerances for hydraulic applications.
Longer lifespan reduces maintenance and replacement costs.
Suitable for hydraulic cylinders, material handling systems, construction machinery, and more.
The production follows strict quality-controlled steps:
High-quality ST52 seamless steel bars are chosen for their machinability and strength.
Rods are machined and straightened to prepare for precision grinding.
Advanced CNC machines grind rods to precise tolerances and surface finishes.
The rod surface is heated by induction, then rapidly cooled, creating a hardened layer of HRC 50-62 while maintaining a tough core.
A uniform chrome layer is applied for corrosion resistance and smooth finish.
Final polishing ensures mirror-like surface roughness (Ra ≤ 0.2μm).
Dimensional, hardness, adhesion, and corrosion tests confirm compliance with standards.
Thanks to its mechanical strength and hardened surface, the rod is widely applied in:
Mobile and industrial hydraulic systems for lifting and pushing.
Excavators, loaders, bulldozers, and cranes.
Tractors, harvesters, and plowing machinery.
Forklifts, lifting platforms, and hoists.
Resistant to corrosion in seawater conditions.
Pneumatic and hydraulic presses, manufacturing machinery.
