Crystalline forms of steel, 2 or 3?
The introduction states "Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic." However, the Properties section states "Depending on the carbon content, the martensitic phase takes different forms. Below 0.2% carbon, it takes on a ferrite BCC crystal form, but at higher carbon content it takes a body-centred tetragonal (BCT) structure."

Should the intro make note of this circumstantial BCT form? CopperGenie (talk) 19:49, 1 January 2023 (UTC)

Is "Electrical steel" a steel?
According to another article, electrical steel is an iron-silicon alloy with extremely low amounts of carbon - .005% or lower. My understanding is carbon has to eliminated from electrical steels, so I wonder if it isn't steel in the usual sense - an iron-carbon alloy.

This article discusses ultra-low carbon steels, also known as deep drawing steel. Sometimes phosphorus is added to help reduce carbides and nitrides and to increase strength.

Is it just common usage to describe an iron-silicon alloy or an iron-phosphorus alloy as a "steel"? Perhaps it's technically incorrect to do so. Or does the lede for this Steel article need to define steel a little more broadly? Should the lede say something like "Steel is usually an alloy of iron and carbon..." or perhaps "Steel is an iron-based alloy. Many varieties of steel have been created to achieve a range of desirable properties. Most steels include carbon for improved strength and fracture resistance compared to other forms of iron".

Should there be a section in the article on "ultra-low carbon steels" that includes electrical steel and DDS? There is no link to the article on Electrical steel from the article on Steel. Should there be?
