ASTM A681 Properties (Chem., Mech. & Rankings) 2022

In this post I'll talk about and give details about ASTM A681. First let's describe it and then have a look at its material's properties.

What is ASTM A681?

ASTM A681 is a Specification for Tool Steels Alloy

Category

Tool Steels

Scope

This specification covers the chemical, mechanical, and physical requirements for available wrought alloy tool steel products.

Ok let's start with ASTM A681 chemical composition.

Chemical Composition

Grade D2

C

1.40 - 1.60

Mn

0.10 - 0.60

P max.

0.030

S max.

0.030

Si

0.10 - 0.60

Cr

11.00 - 13.00

V

0.50 - 1.10

Mo

0.70 - 1.20

Learn more about chemical composition.

Now it's the mechanical properties turn:

Hardness Requirements

Grade D2

255 (annealed) or 269 (Cold Drawn) HB max

Learn more about what is hardness.

Allowable Stress

Depends on the project (And its factor of safety).

Learn more about the what is allowable stress.

My Material's Rank

While 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.

Details and PDF

Instructions:

  1. Go to this page.
  2. Type the name of the standard you are looking for in the search box. Tip: Don't forget to include "ASTM" as a keyword.
  3. Read the details about the standard or download the PDF.

References

Citation

When 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.
