In this post I'll talk about and give details about ASTM A372. First let's describe it and then have a look at its material's properties.
Ok let's start with ASTM A372 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 A372 currently ranks 59 in my yield strength index. This means there are other 58 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 A372?
ASTM A372 is a Specification for Carbon and Alloy Steel Forgings for Thin-Walled Pressure Vessels.Category
Steel Billets and ForgingsScope
This specification covers relatively thin-walled forgings (including gas bottles) for pressure vessel use. Three types of carbon steel and six types of alloy steel are included.Ok let's start with ASTM A372 chemical composition.
Chemical Composition
Grade B
C max.
0.35Mn max.
1.35P max.
0.025S max.
0.025Si
0.15 - 0.35Learn more about chemical composition.
Now it's the mechanical properties turn:
Yield Strength
Grade B

Tensile Strength
Grade B
75 - 100 (515 - 690 MPa)Learn more about what is tensile strength.
Elongation (min.) 50 mm
0.18.Learn more about what is elongation.
Reduction of Area (min. %)
Not Required.Learn more about reduction of area.
Hardness Requirements
Grade B
156 HB min.Learn more about what is hardness.
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 A372 currently ranks 59 in my yield strength index. This means there are other 58 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.
