Requested move[edit]

According to my source, Smith, William F.; Hashemi, Javad (2001), Foundations of Material Science and Engineering (4th ed.), McGraw-Hill, p. 394, ISBN 0-07-295358-6 , low alloy steels are often just called "alloy steels". However, after the move I would also like to add a point to the intro about how alloy steel can also mean any steel with an alloying composition up to 50%. --Wizard191 (talk) 01:23, 12 September 2008 (UTC)

  • Oppose. This is a technical article, and we should use the most accurate technical name. Tevildo (talk) 06:37, 12 September 2008 (UTC)
Per WP standard the common name is supposed to be used (Policy: Wikipedia:Naming_conventions#Use_common_names_of_persons_and_things & guideline: Wikipedia:Naming_conventions_(common_names)). This change would help standardize naming conventions with carbon steel. That article was originally plain carbon steel per the technical name, but was changed to the more common "carbon steel". Just to add another reference, by "Central Steel" catalog lists it as "alloy steels". Even in the technical world we usually just call it "alloy steel". --Wizard191 (talk) 12:21, 12 September 2008 (UTC)

What about beryllium, magnesium, or aluminum?[edit]

For low weight? Sagittarian Milky Way (talk) 05:31, 22 February 2013 (UTC)


I am by no means an expert, but I have the impression the following sentence of the article might be wrong: "With medium to high carbon levels, low-alloy steel is difficult to weld. " Shouldn't the subject of this sentence be something like high-alloy steel? — Preceding unsigned comment added by (talk) 09:39, 20 May 2014 (UTC)

It is true that higher carbon content decreases weldability, and thus that weldability is generally inversely proportional to hardenability, as explained at WP's article on weldability (see for example weldability#Hydrogen-induced cold cracking). This is evidenced by the greater difficulty of welding carbon steel (not low-alloy steel) as the carbon percentage gets higher. It must also no doubt be true of low-alloy steel that, other variables being near equal, higher carbon decreases weldability. So that sentence, by itself, has to be correct. However, the sentences in this article under "low alloy" seemed dubious for various other reasons. I deleted the dubious sentences in this article for now and just left a {{Main}} link to the high-strength low-alloy steel article. Someone can do better here, with refs, in the future, if they choose to. — ¾-10 14:22, 20 May 2014 (UTC)
