Why A500 Steel Pipe?

The specified yield strength of A500 Grade C (the most commonly available grade) is 46 ksi. The specified yield strength of A53 Grade B is 35 ksi. Yield strength increased by more than 30%. Therefore, the strength-to-weight ratio of A500 circular HSS is greater than that of the A53 pipe. So, if you do the job with round HSS, you need less steel, by weight, to do the job—the lighter it is, the lower the cost.
