Materials
Chain piece:40Mn2(common)40MnBn(wear-resisting)
Chain shaw:40Cr
Chain tong:40Cr
Heat Treatment
Chain piece:HRC50°-55° HB270°-297°
Chain pin: HRC55°-60° HB270°-297°
Chain tong: HRC55°-60° HB270°-297°
Main Features
1)Made of special steel material,pin and bush go through special heat treatment . so the wear-resitance is improved to maximum extent .Chain inside is spread with lubrication oil and equipped with polyurethane dust seal and further prolong life time .
2) All chains are assembled with the high precision design and manufacturing parts.so the wear-resitance
3) Differential type of quenching or through type of quenching heat treatment can ensure certain heat treatment hardness depth and so give good anti-cracking effects
