In this post I'll talk about and give details about ASTM A815. First let's describe it and then have a look at its material's properties.
Ok let's start with ASTM A815 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 A815 currently ranks 33 in my yield strength index. This means there are other 32 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 A815?
ASTM A815 is a Specification for Wrought Ferritic, Ferritic/Austenitic, and Martensitic Stainless Steel Piping Fittings.Category
Corrosion-Resisting and Heat-Resisting SteelsScope
This specification covers two general classes, WP and CR, of wrought ferritic, ferritic/austenitic, and martensitic stainless steel fittings of seamless and welded construction.Ok let's start with ASTM A815 chemical composition.
Chemical Composition
Grade UNS S31803
C max.

Hardness Requirements
Grade UNS S31803
290 HBW max.Learn more about what is hardness.
Density
7480 - 8000 kg/m3 (around 7.9 g/cm3 or 0.285 lb/in3).Learn more about density.
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 A815 currently ranks 33 in my yield strength index. This means there are other 32 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.
