What is ASTM A192?
ASTM A192 is a Specification for Seamless Carbon Steel Boiler Tubes for High-Pressure Service.Category
Steel TubesScope
This specification covers minimum-wall thickness, seamless carbon steel boiler and super heater tubes for high pressure service.Ok let's start with ASTM A192 chemical composition.
Chemical Composition
C
0.06 - 0.18Mn
0.27 - 0.63P max.
0.035S max.
0.035Si max.
0.25Learn more about chemical composition.
Now it's the mechanical properties turn:

Density
7800 - 8000 kg/m3 (around 7.9 g/cm3 or 0.285 lb/in3).Learn more about density.
Elastic Modulus
190 GPa (27557 ksi) - 210GPa (30458 ksi).Learn more about the Elastic Modulus.
Poisson's Ratio
0.27 – 0.30.Learn more about the poisson ratio.
Allowable Stress
Depends on the project (And its factor of safety).Learn more about the what is allowable stress.
My Material's Rank
While 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 A192 currently ranks 130 in my yield strength index. This means there are other 129 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.

Citation
When 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 A192 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.
