What is ASTM A453?ASTM A453 is a Specification for High-Temperature Bolting, With Expansion Coefficients Comparable to Austenitic Stainless Steels.
CategorySteel Bolting Materials
ScopeThis specification covers five grades of bolting with twelve classes of yield strength ranging from 50 to 120 ksi (345 to 827 MPa) for use in high-temperature service such as fasteners for pressure vessel and valve flanges.
Ok let's start with ASTM A453 chemical composition.
Ni24.0 - 27.0
Cr13.5 - 16.0
Mo1.00 - 1.50
Ti1.90 - 2.35
V0.10 - 0.50
B0.001 - 0.010

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 A453 currently ranks 16 in my yield strength index. This means there are other 15 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 A453 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.
