DC53是对SKD11进行改良的新型冷作模具钢,其技术规范载于日本工业标准(JIS)G4404。它克服了SKD11高温回火硬度和韧性不足的弱点,将在通用及精密模具领域全面取代SKD11。韧性是SKD11的2倍,DC53的韧性在冷作模具钢中较为突出,用DC53制造的工具很少出现裂纹和开裂,大大提高了使用寿命。
实用特性:
(1)被切削性,被研磨性良好。
被切削性,被研磨性皆比SKD11优秀,所以加工工具寿命较长,加工工时数较省。
(2)在热处理上之优点
淬火硬化能比SKD11高,所以可改善真空热处理时硬度不足之缺陷。
(3)在线切割加工上之优点
藉高温回火可减轻残留应力及消除残留沃斯田铁,能防止线切割加工产生龟裂、变形之困扰。
(4)在表面硬化处理上之优点
表面硬化处理后表面硬度比SKD11高,因此可提高模具性能。
(5)在修补焊接作业上之优点
由于预热及后热温度均比SKD11低,所以修补焊接作业较简便。
DC53模具钢氮化处理:
工件经氮化处理后表面获得致密的硬化层组织,使工件的耐磨性与抗蚀性显著提高。525 ℃气体氮化处理后表层硬度约 1250HV , 570 ℃软氮化处理表层硬度约 950HV 。
密度 DC53比一般模具钢略重,密度为7.9g/cm 3
出厂状态:HB255
