| 2.4869 (DIN 17742 : 2020-12) | NiCr8020 | 2.4869 | DIN 17742 : 2020-12 | Supersedes DIN 17742 : 2002-09 | Valid | Germany | NiCr8020 | 3.4 | ≤ 1200 | 1) |
| 1) Remark: NiCr alloy for furnace components and heating conductors. It is an austenitic nickel-chromium resistance alloy. It is characterised by good scaling resistance as well as resistance under alternating stress in oxidising/ reducing atmospheres, for operating temperatures up to 1250 °C. Use for industrial electric furnaces, enamelling furnaces and night storage furnaces. Formability: good Weldability: satisfactory |
