Punched electron gun part of a Fe-Cr-Ni alloy |
| 摘要 |
A punched part consists of an Fe-Cr-Ni alloy essentially consisting of from 15 to 20% of Cr, from 9 to 15% of Ni, from 0.001 to 0.0050% of S, the balance being Fe and unavoidable impurities. The burrs formed during punching are suppressed due to addition of S to the Fe-Cr-Ni alloy.
