Product Description

42CrMo Chrome Plated Rod Normalized Product Advantages

Choosing 42CrMo Chrome Plated Rod Normalized (HRC 15–22) brings multiple performance and business advantages:


Excellent Mechanical Properties


42CrMo alloy steel provides higher tensile strength and yield strength than standard carbon steels.


Controlled Hardness Range


Normalization ensures stable hardness (HRC 15–22) for machining and hydraulic applications.


Superior Corrosion Resistance


Thick chrome plating prevents rust and surface degradation even in harsh environments.


High Surface Quality


Smooth and mirror-like surface finish reduces friction and extends seal life.


Easy Machinability


Normalized treatment allows easier cutting, drilling, and welding compared to quenched and tempered rods.


Stable Supply for Distributors


Available in standard sizes and customizable lengths to support stockists and engineering projects.


42CrMo Chrome Plated Rod Normalized Production Process

The production of 42CrMo Chrome Plated Rod Normalized (HRC 15–22) follows a precise, multi-step process to guarantee consistent quality:


  1. Raw Material Selection


    Premium 42CrMo alloy steel is sourced with certified chemical composition.


  2. Cutting & Straightening


    Bars are cut to length and straightened to meet strict tolerance requirements.


  3. Normalization Treatment


    Heat treatment is performed to achieve hardness of HRC 15–22, balancing strength and toughness.


  4. Peeling or Grinding


    Surface defects are removed to achieve accurate dimensions and smoothness.


  5. Polishing


    The rod is finely polished to prepare for plating.


  6. Chrome Plating


    Hard chrome is applied, ensuring a uniform layer with high adhesion.


  7. Final Straightening


    The rod is re-straightened to tight tolerances.


  8. Inspection & Testing


    Every rod undergoes dimensional, surface, and hardness testing.
