What is ASTM A681?ASTM A681 is a Specification for Tool Steels Alloy
ScopeThis specification covers the chemical, mechanical, and physical requirements for available wrought alloy tool steel products.
Ok let's start with ASTM A681 chemical composition.
C1.40 - 1.60
Mn0.10 - 0.60
Si0.10 - 0.60
Cr11.00 - 13.00
V0.50 - 1.10
Mo0.70 - 1.20
Learn more about chemical composition.
Now it's the mechanical properties turn:
Grade D2255 (annealed) or 269 (Cold Drawn) HB max
Learn more about what is hardness.
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 A681 currently ranks 165 in my yield strength index. This means there are other 164 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 A681 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.
