Carbon Steel AISI 1020 Forgings | ASTM A576 UNS G10200 Specifications

Carbon Steel AISI 1020 Forgings

G10200, A576

AISI 1020 carbon steel is a commonly used plain carbon steel. It has a good combination of strength and ductility and can be hardened or carburized.
Carbon steels is a category of steel, which contains 0.12 to 2% carbon. This steel category gains hardness and strength with heat treatment when the percentage of carbon content increases but the ductility is reduced.
