ASTM A743 Properties (Chem., Mech. & Rankings)

In this post I'll talk about and give details about ASTM A743. First let's describe it and then have a look at its material's properties.

What is ASTM A743?

ASTM A743 is a Specification for Castings, Iron-Chromium, Iron-Chromium-Nickel, Corrosion Resistant, for General Application

Category

Castings

Scope

This specification covers iron-chromium and iron chromium- nickel alloy castings for general corrosion-resistant application. The grades covered by this specification represent types of alloy castings suitable for broad ranges of application which are intended for a wide variety of corrosion environments.

Ok let's start with ASTM A743 chemical composition.

Chemical Composition

Grade 6A6NM

C max.

0.06

Mn max.

1.00

Si max.

1.00

P Max.

0.04

S max.

0.03

Cr

11.5 - 14.0

Ni

3.5 - 4.5

Mo

0.40 - 1.0

Now it's the mechanical properties turn:

Hardness Requirements

Grade 6A6NM

285 HB max. (Supplementary)

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 A743 currently ranks 168 in my yield strength index. This means there are other 167 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.

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 A743 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.
