What is ASTM A409?ASTM A409 is a Specification for Welded Large Diameter Austenitic Steel Pipe for Corrosive or High- Temperature Service.
CategoryCorrosion-Resisting and Heat-Resisting Steels
ScopeThis specification covers straight seam or spiral seam electric-fusion-welded, light-wall, austenitic chromium- nickel alloy steel pipe for corrosive or high-temperature service.
Ok let's start with ASTM A409 chemical composition.
Ni8.00 - 11.0
Cr18.0 - 20.0
Learn more about chemical composition.
Now it's the mechanical properties turn:
Grade 30430 ksi (205 MPa) min.
Learn more about what is yield strength.
Grade 30475 ksi (515 MPa) min
Learn more about what is tensile strength.
Allowable StressDepends on the project (And its factor of safety).
Learn more about the what is allowable stress.
My Material's RankWhile engineers will often look for the cheapest material they can use, I took a different approach to material's selection to help newbie students.
I ranked materials according to their yield strengths and ASTM A409 currently ranks 121 in my yield strength index. This means there are other 120 materials that are more resistant.
Note: I've analysed 134 materials in order to create an yield strength index. Check my astm material's comparison post for more details.

CitationWhen you need to include a fact or piece of information in an assignment or essay you should also include where and how you found that piece of information.
That gives credibility to your paper and it is sometimes required in higher education.
To make your life (and citation) easier just copy & paste the information below into your assignment or essay:
Luz, Gelson. ASTM A409 Properties (Chem., Mech. & Rankings). Materials Blog. Gelsonluz.com. dd mmmm. yyyy. <URL>
Now replace dd, mmmm and yyyy with the day, month, and year you browsed this page. Also replace URL for the actual url of this page (The < and > stay, ok?). This citation format is based on MLA.
