In this post I'll talk about and give details about ASTM A508. First let's describe it and then have a look at its material's properties.
Ok let's start with ASTM A508 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 A508 currently ranks 17 in my yield strength index. This means there are other 16 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 A508?
ASTM A508 is a Specification for Quenched and Tempered Vacuum-Treated Carbon and Alloy Steel Forgings for Pressure Vessels.Category
Steel Billets and ForgingsScope
This specification covers quenched and tempered vacuum-treated carbon and alloy steel forgings for pressure vessels such as those used in reactor systems. Specifically, it covers forgings for vessel closures, shells, flanges, tube sheets, rings, heads, and similar parts.Ok let's start with ASTM A508 chemical composition.

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 A508 currently ranks 17 in my yield strength index. This means there are other 16 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.
