In this post I'll talk about AISI 904L. First let's describe it and then have a look at its material's properties.
What is AISI 904L?AISI 904L is a high nickel molybdenum stainless steel with a very high corrosion resistance specifically for handling medium concentrated sulfuric acid solutions.
ApplicationChemical industry, petrochemical industry, bleaching equipment in the pulp and paper industry, flue gas cleaning, desalination, seawater handling, hydrometallurgy, food and beverage, pharmaceuticals and heat exchangers.
Ok let's start with AISI 904L Chemical Composition.
C, Carbon max.0.020
Mn, Manganese max.2.00
P, Phosphorus max.0.045
S, Sulfur max.0.035
Si, Silicon max.1.00

AISI Ranking Research (Stainless Steel)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 AISI 904L currently ranks 33 in my yield strength index. This means there are other 32 materials that are more resistant.
Note: I've analysed 77 materials in order to create an yield strength index. Check my material's comparison post for more details.

CitationWhen 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 and paste the information below into your assignment or essay:
Luz, Gelson. AISI 904L Properties (Chem., Mech. & Rankings). Materials Blog. Gelsonluz.com. 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. This citation format is based on MLA.
