Applications

CAN U SPECIFY WHICH GRADE WE PRODUCING PRODUCTS...??? FOR EXAMPLE GRADE 29 USE FOR PRODUCING BOLT

This isn't really the article to discuss that. I know the SAE steel grades article does cover some applications. Wizard191 (talk) 14:06, 13 January 2010 (UTC)

hhgfbbn bn Can someone add 314ss, I think it's also 4841? —Preceding unsigned comment added by 81.149.2.208 (talk) 07:55, 4 June 2010 (UTC)[reply]

Soviet ones?

Does anyone know what standards were used in the Soviet Union? I'm trying to decipher what the "65G, 70 or 75" steel grade might refer to. (Text in Russian: "Его изготавливают из высокоуглеродистой рессорно-пружинной стали марок 65Г, 70, 75 с последующей термической обработкой.") Similarly for the tool grade steel "U12A" (Text in Russian: "вместо малоуглеродистой стали, начали использовать инструментальную сталь У12А"). These both refer to the steel used in the cores of various 7.62x39 ammunition. Someone not using his real name (talk) 07:04, 13 August 2013 (UTC)[reply]

65G for example is detailed here and here. 70 75 U12A. Someone not using his real name (talk)

The first three seem to have an immediate conversion to SAE (10xx), but the U12 stuff, I can't figure out. Someone not using his real name (talk) 08:24, 13 August 2013 (UTC)[reply]

/* References */

Are all the references needed on the article? Do they provide information that is not in the article? https://en.wikipedia.org/w/index.php?title=Steel_grades&diff=prev&oldid=690903637 Contributor1972 (talk) 18:13, 18 March 2017 (UTC)[reply]

Color Codes for API Steel Grade

This section appears to have been copied out of context from information about oil well piping. It makes little sense about tubes, casings and couplings... Stub Mandrel (talk) 19:09, 16 October 2018 (UTC)[reply]
