In this post I'll talk about and give details about ASTM A420. First let's describe it and then have a look at its material's properties.
Ok let's start with ASTM A420 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 A420 currently ranks 95 in my yield strength index. This means there are other 94 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 A420?
ASTM A420 is a Specification for Piping Fittings of Wrought Carbon Steel and Alloy Steel for Low- Temperature Service.Category
Steel Flanges, Fittings, Valves, and PartsScope
This specification covers wrought carbon steel and alloy steel fittings of seamless and welded construction. These fittings are for use in pressure piping and pressure vessel service at low temperatures.Ok let's start with ASTM A420 chemical composition.

Other properties:
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 A420 currently ranks 95 in my yield strength index. This means there are other 94 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.
