# NC 20 TA

名称 NC 20 TA 由 2 个不同牌号共用。请按数值确有差异的元素进行对照，再打开图纸所指的那一个。

- *匹配牌号* **2**
- [*类别* **高温钢／航空用 · 12 个牌号**](/zh/类别/高温钢-航空用 "类别: 高温钢／航空用 · 12 个牌号")
- [*类别* **高温钢 · 40 个牌号**](/zh/类别/高温钢 "类别: 高温钢 · 40 个牌号")

## 这 2 个中，您要哪一个？

该名称由多个牌号共用。表中所列元素是这一组内数值确有差异的元素，也就是决定取舍的元素。数值为来源文本的逐字照录；破折号表示该牌号该元素没有收录数值，而不是零。

| 牌号 | 材料号 | 类别 | 名称数 | P% | Fe% | Co% | Ni% |
|---|---|---|---|---|---|---|---|
| [NiCr20TiAl](/zh/材料/din-en/nicr20tial "NiCr20TiAl") | [2.4631](/zh/材料/材料编号/2.4631 "2.4631") 2.4 | [高温钢／航空用](/zh/类别/高温钢-航空用 "高温钢／航空用") | 11 | 0,03 | ≤1,50 | ≤2,00 | Rest/Bal. |
| [NiCr20TiAl](/zh/材料/din-en/nicr20tial "NiCr20TiAl") | [2.4952](/zh/材料/材料编号/2.4952 "2.4952") 2.4 | [高温钢](/zh/类别/高温钢 "高温钢") | 7 | 0,02 | ≤1,50;(Fe≤3,00) | ≤1,00;(Co≤2,00) | ≥65,0 |
