Alloy L605, also known as Haynes 25, is a cobalt-based superalloy with excellent strength at high temperatures and outstanding oxidation and corrosion resistance. It is widely used in aerospace, turbine engines, medical, and industrial applications. This article introduces the leading global and Chinese manufacturers of L605 round bars, their production capabilities, bar specifications, and export strengths.
Chemical Composition of Alloy L605
| Element | Content (%) |
|---|---|
| Cobalt (Co) | Balance |
| Chromium (Cr) | 19 – 21 |
| Tungsten (W) | 14 – 16 |
| Nickel (Ni) | 9 – 11 |
| Iron (Fe) | 3 max |
| Carbon (C) | 0.05 – 0.15 |
| Manganese (Mn) | 1 – 2 |
| Silicon (Si) | 1 max |
Main Applications of Alloy L605 Bars
