Here are two kind I found on web:
"ASTM A36 is used for general purpose structural, machinery parts, frames, fixtures, automotive and agricultural implements and equipment, brackets, stakes, ornamental works, forgings, base plates, gears, cams, sprockets, jigs, rings, templates, fixtures, bearing plates, tanks, bins, various parts obtained by flame cutting, and miscellaneous non-critical applications that involve mild cold bending, mild hot forming, punching, machining, and welding."
"1045 hot roll plate has a wide variety of applications. It is used for machinery parts, excellent for die forging and hot upsetting, gears, bolster plates, base plates, wear plates, brake dies etc. 1045 hot roll plate can be flame cut to various shapes for a multitude of uses, both in the hardened or annealed condition. Can be hammer forged. 1045 can be used where greater strength is required than can be obtained from the lower carbon steels. It responds to heat treatment, and a wide range of properties can be obtained. In thicker sections, partial hardening increases strength substantially, and flame or induction hardening produces a high surface hardness."
