1)屈服点高、硬度高、冷作硬化效应显着、易出现裂口等缺陷。
(1) Defects such as high yield point, high hardness, remarkable cold hardening effect and easy to crack.
(2)导热性比普通碳钢差，导致所需变形力大，冲裁力、拉深力大。
(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)拉深时塑性变形剧烈硬化，薄板拉深易起皱或掉底。
(3) When drawing, the plastic deformation hardens sharply, and the sheet is easy to wrinkle or drop the guangliang.37ix.com.cnxjtuomoji.37ix.com.cnchuganzhi.37ix.com.c gebin.89ix.comzhulvmen.89ix.comlangfang.75ix.cnbottom.
(4)拉深模具易出现粘接瘤现象，导致零件外径严重划伤。
(4) Deep drawing dies are prone to adhesions, leading to serious scratches on the outer diameter of parts.
