KSP21是一款涂层粉末冶金高速钢（HSS-E-PM）材质，专为钢材料的攻丝加工而设计。该牌号采用PVD TiN涂层，结合粉末冶金高速钢基体，在32-44 HRC的钢材料攻丝加工中具有较好的耐磨性和性能表现。
基体特性
KSP21采用粉末冶金高速钢（HSS-E-PM）基体：
粉末冶金工艺：碳化物分布均匀，晶粒细小，有助于提高切削刃的稳定性和抗崩刃性能
较好的红硬性：可在攻丝加工产生的切削温度下保持硬度
良好的耐磨性：适合加工32-44 HRC的钢材料
应用领域
该牌号主要面向以下材料的攻丝加工场景：
| 材料类别 | 具体材料 | 硬度范围 | 典型应用 |
|---|---|---|---|
| 调质钢 | 合金结构钢、碳素工具钢等 | 32-44 HRC | 汽车零部件、模具、机械零件 |
| 钢材 | 碳钢、合金钢等 | ≤32 HRC | 通用机械零部件 |
