D2是什么材料
D2钢是合金工具钢。
成分:C=1.55%,CR=11.5%,MO=0.7%,V=1.0%,Mn=0.36%,Si=0.3%
特性:富含超硬之合金炭化物,故耐磨性高,韧性佳,耐冲击,很金含量高,故高温抵抗软化力佳,硬化后可实施炭化处理。
使用范围:冷作用模具钢,滚牙、搓牙搓钢珠模板,冲孔模,圆形剪切刀刃、深油拉模、耐磨需求高的塑胶模具。
热处理:球化退火后1000~1050度油淬(HRC63),然后根据所要求的使用性能回火,低温回火100~250度,HRC61~63,适合要求高硬度,高韧性的物件
高温500~550回火3次,HRC58~62,回火后在400~550度区间使用,模具不会减硬度,适合在此温度间使用的高硬度物件!

●特性用用途:
D2是国际上较广泛应用的高碳高铬冷作模具钢,属莱氏体钢,具有高的淬透性、淬硬性和高的耐磨性;高温抗氧化性能好,淬火和抛光后抗锈蚀能力好,热处理变形小。D2宜制造各种高精度、长寿命的冷作模具、刃具和量具,例如:形状复杂的冲孔凹模、冷挤压模、滚丝轮、搓丝轮、冷剪切刀和精密量具等.
●力学性能:
硬度
:退火,≤255HB,压痕直径≥3.8mm;淬火,≥59HRC
●热处理规范及金相组织:
热处理规范:淬火,820±15℃预热,1000±6℃(盐浴)或1010±6℃(炉控气氛)加热,保温10~20min,空冷,200±6℃回火。
●交货状态:钢材以退火状态交货。
D2(SKD-11)是什么材质的
D2材质是Cr12Mo1V1;SKD11材质低于D2。
SKD11和D2的区别
SKD11和D2原本都属于,高碳高铬型冷作模具钢。具有很好的耐磨性和热处理微变形特性,热处理硬度HRC59-61。在连续五金冲压模具和冲头料方面应用广泛。但抗冲击韧性都一般。SKD11和D2的区别有如下几点:
1)出生地不同。SKD11是日本工业部的统称,D2是美国模具钢牌号,合金成分都是Cr12Mo1V1。但中国出品的SKD11合金成分低于D2标准。
2)抗高温软化性能不同。在高速冲压产生高热时,SKD11的硬度下降更快,冲头更容易被磨损。高速冲压模具,D2的耐磨性约是SKD11的2倍。
3)耐磨性性能不同。由于耐磨锌合金钒V含量不同,D2的耐磨性比SKD11优越。
4)淬透性能不同,D2的淬透性能高于SKD11。大型模具用D2模具钢,心部硬度和表面硬度更加均匀。
5)价格不同,D2售价高于SKD11售价。
