Chains. Grade 70, 80 or 100. what do you have and why??

Sweet!
Having all the pieces is nice...some days working with that much is a royal pain...

 

I didn't find the money to buy it

 

There you go wreckin all the fun...
Trust me, I understand!
Fair warning, once you get that rail though, you'll never wanna use your bed again...

 

Dug this up from my crane days.....won't end the debate but the info is there
Look for the difference in WLL & minimum breaking force (how "brittle" it is)

 

The Gr 70/80/100 chain thing brings back memories of my roll cage building days. There was always a debate on what to use:

• "You should use mild (think Gr70) and not CrMo (think Gr 80/100) because the mild will bend and CrMo is brittle and will break before it bends"

• "No, you can use a thinner wall (i.e.- smaller chain) CrMo and get the same strength as mild- they both bend"

I'm sure on some race car board right now there is a thread "Roll cage tubing- 1018 or 4130- what do you use and why"

 

Yes, sorry about that.
