Chain Analysis Reveals Why Formula Matters

The data presented below are the results of an independent lab chemical analysis. The analysis was performed using 10 different industry available drag chains currently selling in the industrial market. Of the 10, we show 6 here because 4 were not even alloy steel making them an unequal comparison to the CDM Systems Chain Formula. The 6 manufacturer’s chain assemblies that use an alloy steel are shown below.

Chemical Analysis and Micro Structure Testing of Various 142MM Pitch Chains

Micro-Structure

  CDM A B C D E
Core Hardness (BHN): 300-400 300-400 300-400 415 300-400 355
Case Hardness (BHN): 550-650 550-650 550-600 535 500-550 550-650
Effective Depth of Case: .035 .022 .025 .010 .012 .055

The Chain Formulation Means the Difference Between Potential Catastrophic Failure and Operating Long-Term at Full Capacity

The most important feature of any drag chain formula is the effective case hardness depth. Once this case is worn through, elongation will accelerate and become a significant factor in maintenance. However, case depth is not unlimited and not the only factor in building a strong chain. The right formula or case hardness and ductility are critical. Too hard, as with a depth noted above of .055 and the ductility and impact resistance will be compromised and cause failures.

CHALLENGE

A power house in the northeastern part of North Dakota needed to upgrade their central heating system. The aging system was costly to operate due to high maintenance and lack of efficiency. See how the CDM ash handling system helped save hundreds-of-thousands of dollars in heating and maintenance costs within the first year.
