ASTM A564 Properties (Chem., Mech. & Rankings) 2022

In this post I'll talk about and give details about ASTM A564. First let's describe it and then have a look at its material's properties.

What is ASTM A564?

ASTM A564 is a Specification for Hot-Rolled and Cold-Finished Age-Hardening Stainless Steel Bars and Shapes.

Category

Corrosion-Resisting and Heat-Resisting Steels

Scope

This specification covers bars and shapes of age hardening stainless steels. Hot-finished or cold-finished rounds, squares, hexagons, bar shapes, angles, tees, and channels are included; these shapes may be produced by hot rolling, extruding, or forging.

Ok let's start with ASTM A564 chemical composition.

Chemical Composition

Grade 630

C max.

0.07

Mn max.

1.00

P max.

0.040

S max.

0.030

Si max.

1.00

Cr

15.00 - 17.50

Ni

3.00 - 5.00

Cu max.

3.00 - 5.00

Learn more about chemical composition.

Now it's the mechanical properties turn:

Yield Strength

Learn more about what is yield strength.

Tensile Strength

Grade 630 (After age hardening H900)

190 ksi (1310 MPa) min.

Learn more about what is tensile strength.

Elongation (min.) 50 mm

0.1.

Learn more about what is elongation.

Reduction of Area (min. %)

0.4.

Learn more about reduction of area.

Hardness Requirements

Grade 630 (After age hardening H900)

388 HB min.

Learn more about what is hardness.

Impact Requirements

Grade 630 (After age hardening H1150D)

41J min.

Learn more about impact testing (charpy v notch).

Other properties:

Density

7480 - 8000 kg/m3 (around 7.9 g/cm3 or 0.285 lb/in3).

Learn more about density.

Elastic Modulus

180 GPa (26107 ksi) - 210GPa (30458 ksi).

Learn more about the Elastic Modulus.

Poisson's Ratio

Usually around 0.26 – 0.31.

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 A564 currently ranks 1 in my yield strength index. This means there are other 0 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 A564 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.
