Material preparation
The company s high-quality products are forgedfrom 40Mn2 round steel. Compared with 50Mnbillets, 40Mn2 has the advantages of lower carboncontent, better product toughness, less prone toedge, finer microstructure andmorewearresistance.
Heat treatment
The chain plates, the driving wheels, the guidingwheels and the idler wheels are treated bymedium frequency heat treatment, and thenstress is removed by tempering to obtain stableproducts with a surface hardness of more thanHRC52.
Track detection
The track after quenching and tempering, thesurface heat treatment hardness is HRCs0-HRC56, the deep layer is 6-8 millimeters, and ithas gone through multiple processes such asmagnetic particle flaw detection and metallographic testing.
Precision forging
After forging, the product structure is moredense, improving the strength of the product andthe reliability of its use.
