What exactly is Sch 40 A53 made of?
(OP)
I can't seem to find any info on what makes Sch 40 pipe, pipe. I know pipe is fairly brittle compared to tube. I know why tube is ductile, because i understand how it's made and what it contains, however, i can't find exact specs on Sch 40. Any help would be appreciated :)
Thanks guys

RE: What exactly is Sch 40 A53 made of?
I don't think that you can generalize that pipe is more brittle than tube. Cast iron pipe is very brittle, but you mentioned A53 in your question, which is not nearly so.
A-53 specifies chemical composition, tensile requirements, bending requiremdnts, flattening testing, hydrostatic testing, NDT of the weld seam (if present), workmanship, finish and appearance.
A-53 pipe comes in several types - Type F:Furnace-butt welded and continuous welded, Type E:Electric-resistance welded, Grades A and B and Type S:Seamless, grades A and B.
For example, A-53 Type S Grade B would be seamless, open-hearth, electric-furnace or basic-oxygen steel with 0.30% max carbon, 1.20% max Manganese, 0.05% max Phosphorus and 0.06% max Sulfur. The tensile requirements are 60,000 psi min, 35,000 psi yield.
This example is from the 1990 version which has surely been updated. Please get the latest version before proceeding further.
Hope this helps...

The designation A53 refers to an ASTM standard
A53/A53M-02 Standard Specification for Pipe, Steel, Black and Hot-Dipped, Zinc-Coated, Welded and Seamless
I haven't seen the standard, but there should be fabrication and composition information in it, or at least references to documents which have that information.

Says that tubes are specified by OD and thickness, while pipes are by a nominal size (or OD/ID if not known) and schedule
High carbon does not automatically give you a high yield strength, a lot of it will depend on heat treatment and fabrication (which can harden the steel).
