What is ASTM A228?ASTM A228 is a Specification for Steel Wire, Music Spring Quality
ScopeThis specification covers a high quality, round, cold drawn steel music spring quality wire, uniform in mechanical properties, intended especially for the manufacture of springs subject to high stresses or requiring good fatigue properties.
Ok let's start with ASTM A228 chemical composition.
C0.70 - 1.00
Mn0.20 - 0.60
Si0.10 - 0.30
Learn more about chemical composition.
Now it's the mechanical properties turn:
6 mm diameter1600 to 1800 MPa
Learn more about what is tensile strength.
Density7800 - 8000 kg/m3 (around 7.9 g/cm3 or 0.285 lb/in3).
Learn more about density.
Elastic Modulus190 GPa (27557 ksi) - 210GPa (30458 ksi).
Learn more about the Elastic Modulus.
Poisson's Ratio0.27 – 0.30.
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 A228 currently ranks 142 in my yield strength index. This means there are other 141 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 A228 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.
