What is ASTM A276?ASTM A276 is a Specification for Stainless Steel Bars and Shapes.
ScopeThis 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.
Grade TP 410
Cr11.50 - 13.50
Learn more about chemical composition.
Now it's the mechanical properties turn:
Grade TP 41040 ksi (275 MPa) min.
Learn more about what is yield strength.
Grade TP 41070 ksi (480 MPa) min.
Learn more about what is tensile strength.
Elongation (min.) 50 mm0.2.
Learn more about what is elongation.
Reduction of Area (min. %)0.45.
Learn more about reduction of area.
Grade TP 420241 HB max.
Learn more about what is hardness.
Density7480 - 8000 kg/m3 (around 7.9 g/cm3 or 0.285 lb/in3).
Learn more about density.
Elastic Modulus180 GPa (26107 ksi) - 210GPa (30458 ksi).
Learn more about the Elastic Modulus.
Poisson's RatioUsually around 0.26 – 0.31.
Learn more about the poisson ratio.
Allowable StressDepends on the project (And its factor of safety).
Learn more about the what is allowable stress.
My Material's RankWhile 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 72 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.

CitationWhen 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. 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.
