Ductility

What happens when your products are not ductile?

Grade definitions 

Common misconception!
There is a common misconception that G10 components do not perform well in extreme environments. The reality is, unlike chain, the grade of a component does not correlate to hardness. Therefore, both the hardness and charpy values of a component, like a master link, must be evaluated to determine if the hardware is suitable for harsh conditions.  Basing the decision on grade alone can put people and property at serious risk.

Fatigue

How to recognize fatigue?

  What is fatigue?

  • Fatigue is the weakening of material caused by repeated loads that leads  to growth of a crack
  • Fatigue can occur at lower load than WLL

 

  Factors affecting fatigue
  resistance:

  • Damage
  • Corrosion
  • The properties of the steel

Combating fatigue:

  • Choose a product that is designed and tested for longer fatigue life
  • Corrosion protection
  • Choose a product with higher WLL

Stages of fatigue

1. Crack Inititation
  • Usually at weak points or damaged areas.

 

2. Crack Growth
  • Slowly at first and then more rapidly

 

3. Catastrophic Failure
