Hi guys, my next door neighbor is an electrician at a large plant here and he did a little dumpster diving for me. He brought me back all these electric motor shafts for me to play with. I have no idea what kind of steel they are other then some form of carbon steel. Magnet sticks to them but I can't say I get a whole lot of small sparks off it. It was hard after the quench and then I did two - 2 hour cycles in the oven with a 1.5 hour cool down in between. Now I'm gonna break it and go all Dave Merkida on it. ( don't know how to spell his name ) It should prove to be interesting. I want to see how tuff this steel is. https://photos.app.goo.gl/kXxwS7uivsZhEzA96
If I recall correctly my WEG motor has a shaft made from 1045. Those lengths of keyed shaft that one can buy are usually 1045 also. https://www.grainger.ca/en/product/KEYED-SHAFT-DIA-1-IN-6-IN-L-CS/p/WWG30F635
IF you have an electrician friend then what you want from him is old wrecked metal tape they use for pulling wires. Every brand I could find info on was a AISI 1075 or equal which makes in expensive knives for cutting leather or patterns.
