Production Process of CK45 Chrome Plated Rod Induction And Hardened (HRC 50-62)

The production of CK45 Chrome Plated Rod Induction And Hardened (HRC 50-62) follows a strict sequence to guarantee premium quality:


  1. Material Selection


    High-grade CK45 steel is sourced and inspected for chemical composition and purity.


  2. Rough Machining


    The rod undergoes turning and peeling to achieve the initial required dimensions.


  3. Heat Treatment


    The steel is normalized and tempered for internal toughness.


  4. Induction Hardening


    High-frequency induction heating and rapid quenching create a hardened surface layer with hardness HRC 50–62.


  5. Precision Grinding


    The rod is centerless ground to achieve exact dimensional tolerance.


  6. Chrome Plating


    A uniform layer of hard chromium is deposited to enhance corrosion resistance and reduce friction.


  7. Polishing


    The plated rod is polished to a smooth mirror finish with a roughness value typically below Ra 0.2μm.


  8. Quality Inspection


    Dimensional, mechanical, and surface quality checks are carried out before packing.
