What is ASTM A493?ASTM A493 is a Specification for Stainless Steel Wire and Wire Rods for Cold Heading and Cold Forging
CategorySteel Wire and Wire Rods
ScopeThis specification covers cold-finished and hot-finished stainless steel wire and wire rods for cold heading or cold forging for applications, such as fasteners, where corrosion resistance is a factor.
Ok let's start with ASTM A493 chemical composition.
Cr18.0 - 20.0
Ni8.0 - 12.0
Learn more about chemical composition.
Now it's the mechanical properties turn:
Grade 304L90 ksi (620 MPa) max.
Learn more about what is tensile strength.
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 A493 currently ranks 155 in my yield strength index. This means there are other 154 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 A493 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.
