管用テーパねじ用のa-tptでインコネルやハステロイの加工は可能か？ | オーエスジー

Is it possible to process Inconel and Hastelloy with A-TPT for tapered threads for pipes?

Basically, we do not recommend it.

For tapered threading for Inconel and Hastelloy pipes, we recommend CPM-TPT for difficult-to-cut materials with Ni-based alloys in the corresponding materials in the catalog.
