Most manufacturers heat treat their components to increase strength and wear properties. However, Diamond Chain Company's proprietary carbon content and special alloy chemistries maximize the effectiveness of the heat treatment process. Because we always use the highest quality raw materials, we are able to obtain maximum carbon diffusion thanks to the advanced atmosphere control system of our state-of-the-art furnace. This proprietary heat-treating process ensures consistent case hardening depth, which results in maximized wear life, less downtime, and lower costs for you.
