What is ASTM A126?ASTM A126 is a Standard Specification for Gray Iron Castings for Valves, Flanges, and Pipe Fittings
CategoryGray iron for castings
ScopeThis specification covers three classes of gray iron for castings intended for use as valve pressure retaining parts, pipe fittings, and flanges.
Ok let's start with ASTM A126 chemical composition.
Learn more about chemical composition.
Now it's the mechanical properties turn:
Class B31 ksi (214 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 A126 currently ranks 136 in my yield strength index. This means there are other 135 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 A126 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.
