 SKD5日本模具钢

SKD5
 执行标准(JIS G4404)   对应国产牌号:3Cr2W8V   对应德国牌号:X30WCrV53(1.2567)   对应美国牌号:H21   对应英国牌号:BH21,BH21A   对应法国牌号:3543Z30WCV9   合金工具钢简称合工钢,是在碳工钢的基础上加入合金元素而形成的钢种。其中合工钢包括:量具刃具用钢、耐冲击工具用钢、冷作模具钢、热作模具钢、无磁模具钢、塑料模具钢。SKD5是热作模具钢。   KD5热作模具钢,是常用的压铸模具钢,有较高的强度和硬度、耐冷热疲劳性良好,且有较好的淬透性,但其韧性和塑性较差。适用制作高温、高应力下,不受冲击负荷的凸模、凹模,如压铸模、热挤压模、精锻模、有色金属成型模等。
化学成分
  C0.30~0.40   Si≤0.40   Mn≤0.40   Cr2.20~2.70   W7.50~9.00   V0.20~0.50   p≤0.030   S≤0.030

热处理
  热处理:(交货状态:布氏硬度HBW10/3000(≤255~207)),淬火:1075~1125,冷却剂:油;
用途
  用途:常用的压铸模具钢。碳含量较低,有较高韧性和良好的导热性;同时,含有较多的碳化物形成元素铬、钨、钒,相变温度提高,使钢有高的高温强度、硬度和良好的耐热疲劳性;淬透。适于制造高温、高应力,但不受冲击负荷的压铸铜、铝、镁合金用附模、型芯、浇口套、分流钉、高应力压腊、热剪切刀、热顶锻模、平锻机凸凹模、镶块等。
