What is ASTM A369?ASTM A369 is a Specification for Carbon and Ferritic Alloy Steel Forged and Bored Pipe for High- Temperature Service.
CategoryCorrosion-Resisting and Heat-Resisting Steels
ScopeThis specification covers heavy-wall carbon and alloy steel pipe made from turned and bored forgings and is intended for high-temperature service.
Ok let's start with ASTM A369 chemical composition.
Mn0.29 - 1.06

Now it's the mechanical properties turn:
Grade FPB35 ksi (240 MPa) min.
Learn more about what is yield strength.
Grade FPB60 ksi (415 MPa) min.
Learn more about what is tensile strength.
Elongation (min.) 50 mm30% (longitudinal).
Learn more about what is elongation.
Reduction of Area (min. %)Not Required.
Learn more about reduction of area.
Density7800 - 8000 kg/m3 (around 7.9 g/cm3 or 0.285 lb/in3).
Learn more about density.
Elastic Modulus190 GPa (27557 ksi) - 210GPa (30458 ksi).
Learn more about the Elastic Modulus.
Poisson's Ratio0.27 – 0.30.
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 A369 currently ranks 94 in my yield strength index. This means there are other 93 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 A369 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.
