# Talk:Steel

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)

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?

Cullen328 changed protection settings for “Steel” yesterday for a duration of one day.  This article should have been semi-protected indefinitely because it’s a high profile article 2603:8080:D03:89D4:E9D7:E06B:32C4:5895 (talk) 23:01, 21 August 2024 (UTC)

How is this possible? The man revolutionized the steel industry. I think we should add a section covering this.  Madaman333 (talk) 16:52, 29 September 2024 (UTC)

Henry Bessemer invented the process that Carnegie invested in. Where would he be mentioned here, an article that provides a broad overview of steel and how it is used throughout the world? If you've got referenced works that describe his influence on steel as a whole that would help but for now he's just got a brief mention in the article History of the iron and steel industry in the United States.

It has been a while since this article has been reviewed, so I took a look and noticed lots of uncited statements, including entire paragraphs. Should this article go to WP:GAR? Z1720 (talk) 01:51, 29 June 2025 (UTC)
