The 4130 from Spruce is all normalized. I do have one suggestion. Buy the strips, not the sheet. The strips are cold rolled so they have a nice smooth finish. 1/8" sheet stock in 4130 is no longer available anywhere in the U.S. in cold rolled, only hot rolled so they have mill scale on them. Unless you were going to water jet them or something and wanted to cut out of a sheet you would want strips cut to width anyway.

The heat treatment is "condition N". You can either start there or end there, but that's the way it needs to be when you're finished. I think when you buy it from AS&S, that's the way it is, but I'd check to make sure.
