Description Technical Specs
 
WHX78 chain is a 2.609" pitch offset-sidebar chain that is manufactured to be high-strength and heavy duty. Typically WHX78 chain is supplied as a "cottered" style welded steel chain but riveted is also available. Our high-strength WHX78 chain is manufactured to American Standards and uses high-quality steel alloys that are heat-treated and hardened for optimum performance and the best overall durability. WHX series welded steel chains have become a preferred choice in heavy-duty grain handling, forestry, and conveying applications. Dimensionally WHX78 and WH78 chain are the same but more specifically WHX78 chain uses "case-hardened" pins instead of through hardened like the standard WH series chains use.

Case Hardened vs. Through Hardened:
Case hardening is the process of hardening just the surface of the part, also commonly known as carburizing. In the case hardening process, the low carbon component is placed in a furnace which contains a carefully controlled carbon atmosphere. It remains there for a period of time so the carbon soaks into the parts surfaces to a predetermined depth. When the part is heat-treated, the high carbon surface layer becomes hard while the low carbon core remains comparatively soft.
Through Hardening is done where the iron mix contains a certain amount of carbon. Carbon dissolves in molten iron just as sugar would dissolve in coffee. In through hardening steel, there is a high level of carbon added to the iron mix. When the component is heat treated, it becomes hard all the way through from the surface to the core. This is why the term "through hardened" is used.
The Verdict:
Through-hardened steel is a lot more brittle and can fracture under impact or shock loads while the case hardened steel has a softer core which drastically reduces the possibility of a fracture or breakage.

Most commonly WHX78 chain is accompanied with polyethylene flights of various forms bolted to steel backing plates that are welded directly to the chain. We also supply these flights and backing plates and can place them onto the chain in any configuration needed. Additionally, we stock a wide range of WHX78 sprockets!
