ASTM A182 Properties (Chem., Mech. & Rankings) 2022

In this post I'll talk about and give details about ASTM A182. First let's describe it and then have a look at its material's properties.

What is ASTM A182?

ASTM A182 is a Specification for Forged or Rolled Alloy and Stainless Steel Pipe Flanges, Forged Fittings, and Valves and Parts for High-Temperature Service.


Corrosion-Resisting and Heat-Resisting Steels


This specification covers forged low alloy and stainless steel piping components for use in pressure systems. Included are flanges, fittings, valves, and similar parts.

Ok let's start with ASTM A182 chemical composition.

Chemical Composition

Grade F22 Class 1


0.05 - 0.15


0.30 - 0.60

P max.


S max.


Si max



2.00 - 2.50


0.87 - 1.13

Learn more about chemical composition.

Now it's the mechanical properties turn:

Yield Strength

Grade F22 Class 1

30 ksi (205 MPa) min

Learn more about what is yield strength.

Tensile Strength

Grade F22 Class 1

60 ksi (415 MPa) min

Learn more about what is tensile strength.

Elongation (min.) 50 mm


Learn more about what is elongation.

Reduction of Area (min. %)

Not Required.

Learn more about reduction of area.

Hardness Requirements

Grade F22 Class 1

170 HBW mรกx.

Learn more about what is hardness.

Impact Requirements

Grade F 3V

54J avg 48J min

Learn more about impact testing (charpy v notch).

Other properties:


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 A182 currently ranks 105 in my yield strength index. This means there are other 104 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 A182 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.
