What is ASTM A29?ASTM A29 is a Specification for Steel Bars, Carbon and Alloy, Hot-Wrought, General Requirements for 121 tion for Steel Rivets and Bars for Rivets, Pressure Vessels.
ScopeThis specification covers a group of common requirements which, unless otherwise specified in the purchase order or in an individual specification, shall apply to carbon and alloy steel bars.
Ok let's start with ASTM A29 chemical composition.
C0.38 - 0.43
Mn0.75 - 1.00
Si0.15 - 0.35
Cr0.80 - 1.1
Mo0.15 - 0.25
Learn more about chemical composition.
Now it's the mechanical properties turn:
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 A29 currently ranks 146 in my yield strength index. This means there are other 145 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 A29 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.
