What is ASTM A1018?ASTM A1018 is a Standard Specification for Steel, Sheet and Strip, Heavy-Thickness Coils, Hot-Rolled, Carbon, Commercial, Drawing, Structural, High-Strength Low-Alloy, and High-Strength Low-Alloy with Improved Formability
CategorySheet and Strip Coils
ScopeThis specification covers hot-rolled, heavy-thickness coils beyond the size limits of Specification A 1011/A 1011M.
Ok let's start with ASTM A1018 chemical composition.
hslas grade 50 class 1

Now it's the mechanical properties turn:
Grade 50 class 150 ksi (340 MPa) min
Learn more about what is yield strength.
Grade 50 class 165 ksi (450 MPa) min
Learn more about what is tensile strength.
Elongation (min.) 50mm0.2.
Learn more about what is elongation.
Reduction of Area (min. %)Not Required.
Learn more about reduction of area.
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 A1018 currently ranks 53 in my yield strength index. This means there are other 52 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 A1018 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.
