1)屈服點高、硬度高、冷作硬化效應顯著、易出現裂口等缺陷。
(1) Defects such as high yield point, high hardness, remarkable cold hardening effect and easy to crack.
(2)導熱性比普通碳鋼差，導致所需變形力大，沖裁力、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)拉深時塑性變形劇烈硬化，薄板拉深易起皺或掉底。
(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)拉深模具易出現粘接瘤現象，導致零件外徑嚴重劃傷。
(4) Deep drawing dies are prone to adhesions, leading to serious scratches on the outer diameter of parts.
