What is the process of chromed bar/ piston rod?
Update Time:2018-04-11

the rods first undergo precision milling and processing, and are then put through grind surface chromium treatment, allowing a surface precision level of f8, and a surface hardness reaching HV850 minimum and up, which not only help to improve wear resistance but also help to extend the life cycle of the rods, thus helping the customer save cost.
