Product Description
Choosing 42CrMo Chrome Plated Rod Normalized (HRC 15–22) brings multiple performance and business advantages:
42CrMo alloy steel provides higher tensile strength and yield strength than standard carbon steels.
Normalization ensures stable hardness (HRC 15–22) for machining and hydraulic applications.
Thick chrome plating prevents rust and surface degradation even in harsh environments.
Smooth and mirror-like surface finish reduces friction and extends seal life.
Normalized treatment allows easier cutting, drilling, and welding compared to quenched and tempered rods.
Available in standard sizes and customizable lengths to support stockists and engineering projects.
The production of 42CrMo Chrome Plated Rod Normalized (HRC 15–22) follows a precise, multi-step process to guarantee consistent quality:
Premium 42CrMo alloy steel is sourced with certified chemical composition.
Bars are cut to length and straightened to meet strict tolerance requirements.
Heat treatment is performed to achieve hardness of HRC 15–22, balancing strength and toughness.
Surface defects are removed to achieve accurate dimensions and smoothness.
The rod is finely polished to prepare for plating.
Hard chrome is applied, ensuring a uniform layer with high adhesion.
The rod is re-straightened to tight tolerances.
Every rod undergoes dimensional, surface, and hardness testing.
The 42CrMo Chrome Plated Rod Normalized (HRC 15–22) is widely adopted in multiple industries requiring durable and corrosion-resistant piston rods:
For construction machinery, cranes, mining equipment.
High-performance actuators for automation.
Tractors, harvesters, and loaders.
Press machines, injection molding machines.
Offshore equipment requiring high corrosion resistance.
Forklifts and lifting platforms.
