Specifications
Harvester Chains used in different kinds of tractors, including combine chains and rice harvester.High quality alloy material ensure the harden of hole-making model, we change the model very often no matter whether the model attrite or not , so we can make sure the bright area of roller chain plate inner hole. Its known to all that good bright area of inner hole good for anti fatigue.
Our Dongsheng chains fit standard of ISO, ANSI, DIN, and JIS, its heat treatment is advanced and material is selected alloy steel. The products have been sold to the whole country and Europe, American, Middle-east and South-East Asia.
The Chain technic treatment is as below:
Shot peening
Bluing
Phosphating
Nickel-plated
Zincing
Heat treatment
Carburizing
Quenching
Tempering
Oiling
