AS 1548 Properties (Chem., Mech. & Rankings) rev. 2021

In this post I'll talk about and give details about AS 1548. First let's describe it and then have a look at its material's properties.

What is AS 1548?

AS 1548 is a Specification for Fine Grained, Weldable Steel Plates for Pressure Equipment.

Category

Steel Plates, Sheets, and Strip for Pressure Vessels

Scope

Specifies requirements for hot-rolled, fine grained, fully killed carbon manganese steel plates to a maximum thickness of 150 mm for use in the construction of pressure equipment.

Ok let's start with AS 1548 chemical composition.

Now it's the mechanical properties turn:

Yield Strength

Learn more about what is yield strength.

Tensile Strength

Designation PT460

460 to 580 MPa

Learn more about what is tensile strength.

Elongation (min.)

0.21.

Learn more about what is elongation.

Reduction of Area (min. %)

Not Required.

Learn more about reduction of area.

Impact Requirements

Designation PT460 L20

35J @-20ÂșC

Learn more about impact testing (charpy v notch).

Other properties:

Density

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 AS 1548 currently ranks 63 in my yield strength index. This means there are other 62 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. AS 1548 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.
