In this post I'll talk about and give details about ASTM A131. First let's describe it and then have a look at its material's properties.
Ok let's start with ASTM A131 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 impact testing (charpy v notch).
Other properties:
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 A131 currently ranks 98 in my yield strength index. This means there are other 97 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 the difference between Code, Standard & Specification?

What is ASTM A131?
ASTM A131 is a Specification for Structural Steel for ShipsCategory
Structural SteelScope
This specification covers structural steel plates, shapes, bars, and rivets intended primarily for use in ship construction.Ok let's start with ASTM A131 chemical composition.

Other properties:
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 A131 currently ranks 98 in my yield strength index. This means there are other 97 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.
