In this post I'll talk about and give details about ASTM A841. First let's describe it and then have a look at its material's properties.
Ok let's start with ASTM A841 chemical composition.
Learn more about chemical composition.
Now it's the mechanical properties turn:
Learn more about what is yield strength.
Learn more about what is tensile strength.
Learn more about what is elongation.
Learn more about reduction of area.
Learn more about density.
Learn more about the Elastic Modulus.
Learn more about the poisson ratio.
Learn more about the what is allowable stress.
I ranked materials according to their yield strengths and ASTM A841 currently ranks 22 in my yield strength index. This means there are other 21 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.

What is ASTM A841?
ASTM A841 is a Specification for Steel Plates for Pressure Vessels, Produced by Thermo-Mechanical Control Process (TMCP).Category
Steel Plates, Sheets, and Strip for Pressure VesselsScope
This specification covers steel plates produced by the thermo-mechanical control process (TMCP). The plates are intended primarily for use in welded pressure vessels.Ok let's start with ASTM A841 chemical composition.

Reduction of Area (min. %)
Not Required.Learn more about reduction of area.
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 A841 currently ranks 22 in my yield strength index. This means there are other 21 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.
