    Our advantage: 
    • Real quenching process to ensure core hardness with at least HRC20 or up 
    • Surface hardness with HRC56-60 
    •Medium frequency heat treatment instead of high-frequency to ensure the thickness of hardness more than 1.8mm 
    • Longer wear life

Our advantage: 
• Real quenching process to ensure core hardness with at least HRC20 or up 
• Surface hardness with HRC56-60 
•Medium frequency heat treatment instead of high-frequency to ensure the thickness of hardness more than 1.8mm 
• Longer wear life 
• Excellent surface plating, including hard Chrome plate can be chosen 
• Material:40CR or 42CRMO material can be chosen 

Our quality advantage: 
·Wearlessness: For pins, after quenching and tempering, then do surface intermediate frequency treatment, to assure the enough inside hardness and outside wearlessness.
