In this post I'll talk about and give details about ASTM A693. First let's describe it and then have a look at its material's properties.
Ok let's start with ASTM A693 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 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 A693 currently ranks 2 in my yield strength index. This means there are other 1 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 A693?
ASTM A693 is a Specification for Precipitation-Hardening Stainless and Heat-Resisting Steel Plate, Sheet, and Strip.Category
Steel Plates, Sheets, and Strip for Pressure VesselsScope
This specification covers precipitation-hardening stainless steel plate, sheet, and strip. The mechanical properties of these steels are developed by suitable low-temperature heat treatments generally referred to as precipitation hardening.Ok let's start with ASTM A693 chemical composition.

Elastic Modulus
180 GPa (26107 ksi) - 210GPa (30458 ksi).Learn more about the Elastic Modulus.
Poisson's Ratio
Usually around 0.26 – 0.31.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 A693 currently ranks 2 in my yield strength index. This means there are other 1 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.
