Product Details
ASTM 1020 Carbon Steel Hot Rolling / Polishing Round Bar
The strength is slightly higher than that of 1015 steel, with
little quenching and no temper brittleness. Cold deformation has
high plasticity and is generally used for bending, calendering,
bending and hammer arch processing. The welding performance of
electric arc welding and contact welding is good. The thickness of
gas welding is small, and cracks are easy to occur on the parts
with strict shape requirements or complex shape. The machinability
of cold drawing or normalizing state is better than that of
annealing state, which is generally used for manufacturing with low
stress and high toughness requirements.,
