ASTM A517 Properties (Chem., Mech. & Rankings)

In this post I'll talk about and give details about ASTM A517. First let's describe it and then have a look at its material's properties.

What is ASTM A517?

ASTM A517 is a Specification for Pressure Vessel Plates, Alloy Steel, High-Strength, Quenched and Tempered.


Steel Plates, Sheets, and Strip for Pressure Vessels


This specification covers high-strength quenched and tempered alloy steel plates intended for use in fusion welded boilers and other pressure vessels.

Ok let's start with ASTM A517 chemical composition.

Chemical Composition

Grade F


0.10 - 0.20


0.60 - 1.00

P max.


S max.



0.15 - 0.35


0.70 - 1.00


0.40 - 0.65


0.40 -0.60


0.0005 - 0.006


0.03 - 0.08


0.15 - 0.50

Now it's the mechanical properties turn:

Yield Strength

65mm and under

100 ksi (690 MPa) min.

Learn more about what is yield strength.

Tensile Strength

65mm and under

115 - 135 ksi (795 - 930 MPa)

Learn more about what is tensile strength.

Elongation (min.) 50 mm


Learn more about what is elongation.

Reduction of Area (min. %)

35% (rectangular).

Learn more about reduction of area.

Impact Requirements

Charpy V-notch impact test specimens shall have a lateral expansion opposite the notch of not less than 0.015 in. (0.38 mm).

Learn more about impact testing (charpy v notch).

Other properties:


7800 - 8000 kg/m3 (around 7.9 g/cm3 or 0.285 lb/in3).

Learn more about density.

Elastic Modulus

190 GPa (27557 ksi) - 210GPa (30458 ksi).

Learn more about the Elastic Modulus.

Poisson's Ratio

0.27 – 0.30.

Learn more about the poisson ratio.

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 A517 currently ranks 9 in my yield strength index. This means there are other 8 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.

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 A517 Properties (Chem., Mech. & Rankings). Materials Blog. 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.
