ASTM A276 Properties (Chem., Mech. & Rankings) 2022

In this post I'll talk about and give details about ASTM A276. First let's describe it and then have a look at its material's properties.

What is ASTM A276?

ASTM A276 is a Specification for Stainless Steel Bars and Shapes.


Steel Bars


This specification covers hot-finished or cold-finished bars except bars for reforging. It includes rounds, squares, and hexagons, and hot-rolled or extruded shapes, such as angles, tees, and channels in the more commonly used types of stainless steels.

Ok let's start with ASTM A276 chemical composition.

Chemical Composition

Grade TP 410

C max.


Mn max.


P max.


S max.


Si max.



11.50 - 13.50

Learn more aboutĀ chemical composition.

Now it's the mechanical properties turn:

Yield Strength

Grade TP 410

40 ksi (275 MPa) min.

Learn more aboutĀ what is yield strength.

Tensile Strength

Grade TP 410

70 ksi (480 MPa) min.

Learn more aboutĀ what is tensile strength.

Elongation (min.) 50 mm


Learn more aboutĀ what is elongation.

Reduction of Area (min. %)


Learn more aboutĀ reduction of area.

Hardness Requirements

Grade TP 420

241 HB max.

Learn more aboutĀ what is hardness.


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

Learn more aboutĀ density.

Elastic Modulus

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

Learn more about theĀ Elastic Modulus.

Poisson's Ratio

Usually around 0.26 ā€“ 0.31.

Learn more about theĀ poisson ratio.

Allowable Stress

Depends on the project (And its factor of safety).

Learn more about theĀ 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 A276 currently ranks 72Ā in my yield strength index. This means there are other 71 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 A276 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.
