Production Process of 42CrMo4 Chrome Plated Rod

The 42CrMo4 Chrome Plated Rod undergoes a precise and controlled production process to ensure strength, quality, and performance:


  1. Raw Material Selection


    Premium 42CrMo4 alloy steel is chosen for strength and machinability.


  2. Cutting and Rough Machining


    Bars are cut and processed to required dimensions.


  3. Heat Treatment (Quenching & Tempering)


    Improves overall toughness and durability.


  4. Peeling and Grinding


    Ensures accurate diameter and surface preparation.


  5. Induction Hardening


    Hardens the surface to HRC 50-62 while maintaining a tough core.


  6. Polishing


    Creates a smooth, low-friction finish.


  7. Chrome Plating


    Provides corrosion resistance and surface protection.


  8. Final Inspection


    Comprehensive testing for hardness, plating thickness, straightness, and roughness.
