Material Name: high quality carbon structural steel
Grade: 1020
Standard: AISI
● Features and application:
Higher strength steel than 15, rarely quenching, no temper brittleness. Cold plastic deformation is high, usually for bending, rolling, curved edges and hammer arch and other processing, and exposure to welding arc welding performance is good, gas welding when the thickness is small, form-critical or complex shape of the workpiece on the crack-prone. Machinability than cold drawn annealed or normalized condition is good, generally used for manufacturing large discontinuity toughness demanding?,
