ASTM A694 Properties (Chem., Mech. & Rankings)

In this post I'll talk about and give details about ASTM A694. First let's describe it and then have a look at its material's properties.

What is ASTM A694?

ASTM A694 is a Specification for Carbon and Alloy Steel Forgings for Pipe Flanges, Fittings, Valves, and Parts for High-Pressure Transmission Service

Category

Pipe Flanges, Fittings and Valves

Scope

This specification covers forged or rolled steel pipe flanges, forged fittings, valves, and parts suitable for use with high-strength transmission-service pipe. Included are flanges, fittings, and similar parts.

Ok let's start with ASTM A694 chemical composition.

Chemical Composition

Grade F65

C max.

0.26

Mn max.

1.40

P max.

0.025

S max.

0.025

Si

0.15 - 0.35

Learn more about chemical composition.

Now it's the mechanical properties turn:

Yield Strength

Grade F65

65 ksi (450 MPa) min.

Learn more about what is yield strength.

Tensile Strength

Grade F65

77 ksi (530 MPa) min.

Learn more about what is tensile strength.

Elongation (min.) 50 mm

0.2.

Learn more about what is elongation.

Reduction of Area (min. %)

Not Required.

Learn more about reduction of area.

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 A694 currently ranks 31 in my yield strength index. This means there are other 30 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.

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 A694 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.
