SAE 1018 | AISI 1018 CARBON STEEL-ASTM A29
SAE 1018 is a low carbon steel that belongs to carbon structural steel as per ASTM A29.
As a low carbon steel, SAE 1018 steel has good plasticity and toughness, excellent cold forming performance and machinability. In addition, it also has good welding performance, and can be further improved by heat treatment to improve hardness and strength.
SAE 1018 steel is suitable for manufacturing low-strength welded parts, cold stamped parts, forgings and carburized parts, etc.
