In this post I'll talk about and give details about ASTM A487. First let's describe it and then have a look at its material's properties.
Ok let's start with ASTM A487 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 what is hardness.
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 A487 currently ranks 23 in my yield strength index. This means there are other 22 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 A487?
ASTM A487 is a Specification for Steel Castings Suitable for Pressure Service.Category
Steel CastingsScope
This specification covers low-alloy steels and martensitic stainless steels in the normalized and tempered, or quenched and tempered, condition suitable for pressure containing parts.Ok let's start with ASTM A487 chemical composition.

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 A487 currently ranks 23 in my yield strength index. This means there are other 22 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.
