ASTM A263 Properties⚙️ (Chem., Mech. & Rankings) rev. 2022

In this post I'll talk about and give details about ASTM A263. First let's describe it and then have a look at its material's properties.

What is ASTM A263?

ASTM A263 is a Specification for Stainless Chromium Steel-Clad Plate.


Steel Plates, Sheets, and Strip for Pressure Vessels


This specification covers plate of a carbon steel or low-alloy steel base to which is integrally and continuously bonded on one or both sides a layer of stainless chromium steel. The material is generally intended for pressure vessel use.

Ok let's start with ASTM A263 chemical composition.

Chemical Composition

Alloy Cladding Metal

Shall conform to the requirements as to chemical composition prescribed for the respective chromium steel in Specification A240/A240M.

Base Metal

The base metal shall be carbon steel or low-alloy steel conforming to the ASTM specifications for steels for pressure vessels or other as agreed by the purchaser and the manufacturer.

Now it's the mechanical properties turn:

Yield Strength

40 ksi (275 MPa) min

Learn more about what is yield strength.

Tensile Strength

70 ksi (485 MPa) min

Learn more about what is tensile strength.


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 A263 currently ranks 70 in my yield strength index. This means there are other 69 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.

ASTM Classroom

Are you having trouble understanding the basics of ASTM?

What is the difference between Code, Standard & Specification?

This video will walk you through:



When you need to include a fact or piece of information in an assignment or essay you should also include where and how you found that piece of information.

That gives credibility to your paper and it is sometimes required in higher education.

To make your life (and citation) easier just copy & paste the information below into your assignment or essay:

Luz, Gelson. ASTM A263 Properties (Chem., Mech. & Rankings). Materials Blog. dd mmmm. yyyy. <URL>

Now replace dd, mmmm and yyyy with the day, month, and year you browsed this page. Also replace URL for the actual url of this page (The < and > stay, ok?). This citation format is based on MLA.
