IA vs IC pipe
IA vs IC pipe
(OP)
What is the basis for describing pipes as group IA vs IC? For example, looking at ASTM standard spec F1043-06 for industrial chain link fence framework, the Group IA designation is given to 30000psi steel, where the IC is for 500000 psi steel. So the IC has a lower weight per unit length for the same strength. It would seem that IA or IC could be used interchangeably, and the choice might depend upon price. Anti-corrosive coatings seem to be treated separately, so that there, again, it comes down to price, IC not being inferior to IA. ??

I think you've got the wrong forum.

You might get a better answer for chain link fence frameworks in a forum like Metal and Metallurgy Engineering in the Materials group.
