What is ASTM A358?ASTM A358 is a Specification for Electric-Fusion-Welded Austenitic Chromium-Nickel Stainless Steel Pipe for High-Temperature Service and General Applications.
CategoryCorrosion-Resisting and Heat-Resisting Steels
ScopeThis specification covers electric-fusion-welded austenitic chromium-nickel stainless steel pipe suitable for corrosive or high-temperature service, or both, or for general applications.
Ok let's start with ASTM A358 chemical composition.
Cr17.5 - 19.5
Ni8.0 - 10.5
Learn more about chemical composition.
Now it's the mechanical properties turn:

Density7480 - 8000 kg/m3 (around 7.9 g/cm3 or 0.285 lb/in3).
Learn more about density.
Elastic Modulus180 GPa (26107 ksi) - 210GPa (30458 ksi).
Learn more about the Elastic Modulus.
Poisson's RatioUsually around 0.26 – 0.31.
Learn more about the poisson ratio.
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 A358 currently ranks 118 in my yield strength index. This means there are other 117 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 A358 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.
