(1) Defects such as high yield point, high hardness, remarkable cold hardening effect and easy to crack.
(2) The thermal conductivity is worse than that of ordinary carbon
steel, which results in large deformation force, large blanking force
and deep drawing force.
(3) When drawing, the plastic deformation hardens sharply, and the sheet
is easy to wrinkle or drop the
(4) Deep drawing dies are prone to adhesions, leading to serious scratches on the outer diameter of parts.
