I have been looking for chemical specifications for steel grades from the early 20th century. Specifically, I want to know what the chemical analysis limits for 1020 steel were in about 1920. Same as today, or not? ASTM only lists old standards going back to about the '90s. I have found all sorts of old manuals with structural steel beam dimensions and some physical properties, but nothing with grade chemistries going back that far. Does anyone have any resources or suggestions?
