What is ASTM A351?ASTM A351 is a Specification for Castings, Austenitic, Austenitic-Ferritic (Duplex), for Pressure- Containing Parts.
CategoryCorrosion-Resisting and Heat-Resisting Steels
ScopeThis specification covers austenitic and austenitic ferritic (duplex) steel castings for valves, flanges, fittings, and other pressure-containing parts.
Ok let's start with ASTM A351 chemical composition.
Cr18.0 - 21.0
Ni8.0 - 11.0
Learn more about chemical composition.
Now it's the mechanical properties turn:
Grade CF830 ksi (205 MPa) min
Learn more about what is yield strength.
Grade CF870 ksi (485 MPa) min.
Learn more about what is tensile strength.
Elongation (min.) 50 mm0.35.
Learn more about what is elongation.
Reduction of Area (min. %)Not Required.
Learn more about reduction of area.
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 A351 currently ranks 117 in my yield strength index. This means there are other 116 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 A351 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.
