Application Scenarios

Where Grade 43 High Test Chain NACM2010 Is Used

  • Securing heavy cargo on flatbed trailers during long-haul transport where vibration and weather exposure are factors
  • Logging operations where chains are used to pull or stabilize felled timber on rough terrain
  • Marine mooring and anchoring where exposure to saltwater demands corrosion-resistant hardware
  • Industrial rigging for non-lifting tasks such as pulling, bracing, or stabilizing structures
  • Towing and recovery operations on construction sites or off-road environments with high mechanical stress
  • Load binding in manufacturing or warehouse settings where chains are used to secure stacked or bulky items

How It Compares With The Alternatives

An honest read on where this pattern wins and where another one would serve you better.

AlternativeHonest Trade Off
Grade 30 Proof Coil ChainGrade 43 has higher tensile strength and is heat-treated, making it suitable for heavier loads and repeated stress, whereas Grade 30 is for light-duty applications only
Grade 80 Alloy ChainGrade 43 is not rated for overhead lifting; Grade 80 is required for lifting applications and has higher alloy content and safety factor
Standard Carbon Steel ChainGrade 43 is heat-treated and proof tested, offering better strength and durability than non-heat-treated chains
Synthetic Webbing SlingsGrade 43 chain offers superior resistance to abrasion and heat, but is heavier and less flexible than synthetic slings
Use Guide

How To Use And Inspect Grade 43 High Test Chain NACM2010

  • Never exceed the stamped working load limit on the chain
  • Inspect the chain before each use for wear, deformation, or weld defects
  • Use only in applications that do not require overhead lifting
  • Avoid side loading or sharp bends that can reduce strength and cause failure
  • Clean and dry the chain after exposure to saltwater or moisture to maintain finish
  • Replace the chain if the working load limit marking is illegible or if the chain shows signs of elongation or damage

Answers

Grade 43 High Test Chain NACM2010 FAQ

Is Grade 43 chain rated for overhead lifting?
No. Grade 43 chain is not rated for overhead lifting. Use Grade 80 or Grade 100 alloy chains for lifting applications.
What is the design factor for this chain?
The design factor is 3:1, meaning the minimum breaking force is three times the stated working load limit.
What finishes are available?
Available finishes include galvanized, zinc-plated, and self-color. Custom finishes can be requested.
Can you provide a Material Test Certificate?
Yes. A Material Test Certificate to EN 10204 3.1 is supplied with each order on request.
Are custom sizes available?
Yes. Custom sizes beyond the standard 1/4 inch to 7/8 inch range are available on request.
How is the chain marked?
The working load limit and minimum breaking force are stamped on the chain for traceability and safety.
