416 ステンレスシート
416 stainless steel sheet is a free-machining martensitic stainless steel に最適化された high-speed machining and precision parts production.
その high sulfur content improves machinability but reduces corrosion resistance and weldability. Compared to austenitic grades like 304, it is better suited for mechanical components rather than corrosive environments.
- 説明
416 stainless steel sheet is a マルテンサイト系ステンレス鋼 のために設計された excellent machinability. It is a free-machining grade derived from 410 ステンレス鋼, with the addition of sulfur to improve cutting performance.
It combines moderate corrosion resistance with high machinability, making it widely used for precision-machined components.
