In this post I'll talk about and give details about ASTM A574. First let's describe it and then have a look at its material's properties.
Ok let's start with ASTM A574 chemical composition.
Learn more about chemical composition.
Now it's the mechanical properties turn:
Learn more about what is tensile strength.
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 A574 currently ranks 159 in my yield strength index. This means there are other 158 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 A574?
ASTM A574 is a Specification for Alloy Steel Socket-Head Cap Screws.Category
Steel Bolting MaterialsScope
This specification covers the requirements for quenched and tempered alloy steel hexagon socket-head cap screws, 0.060 through 4 in. in diameter where high strength is required.Ok let's start with ASTM A574 chemical composition.
Chemical Composition
Grade 4037 (Composition non mandatory)
C
0.35 - 0.40Mn
0.70 - 0.90P max.
0.035S max.
0.040Si
0.15 - 0.35Mo
0.20 - 0.30Learn more about chemical composition.
Now it's the mechanical properties turn:
Tensile Strength
1 in diameter
103000 lbf min and 81800 lbf proof load (Min)Learn more about what is tensile strength.
Hardness Requirements
Finished screws
39 to 45 HRCLearn 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 A574 currently ranks 159 in my yield strength index. This means there are other 158 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.
