Initially I was going to use 1018 CRS so that squaring the bar would be easier But I've read that if CRS is machined, it can warp due to internal stresses While A36 is the more costeffective of the two metals, 1018 wins out in most other classes for quality Measurements for warmrolled A36 are additionally not as exact as coldrolled steels since they warp and bend barely during the cooling course ofAlloy 1018 is the most commonly available of the coldrolled steels It is generally available in round rod, square bar, and rectangle bar It has a good combination of all of the typical traits of steel strength, some ductility, and comparative ease of machining Chemically, it is very similar to A36 Hot Rolled steel, but the cold rolling process creates a better surface finish and better properties
