| 2.4608 (DIN 17744 : 2002-09) | NiCr26MoW | 2.4608 | DIN 17744 : 2002-09 | DIN 17744 : 2002-09 replaced by DIN 17744 : 2020-12 | Replaced | Germany | NiCr26MoW | 3.4 | ≤ 1200 | 1) |
| 1) Remark: The material NiCr26MoW with the material number 2.4608 is applied in the form of strips, sheets, bars, and wires for highly heat-resistant construction components. The alloy is marked by very good mechanical properties and creep strength depending on time up to 1200 °C, by excellent resistance to carbonizing, oxidation and sulphurization and by good resistance to stress cracking corrosion. Owing to the trend towards higher operating temperatures in chemical processes and to more agressive mediums, the material finds a wide range of application. Typical fields of application are furnace parts, e.g. furnace muffles, fans in the hot-gas area, furnace rolls and steel tubes, facilities in the chemical and petrochemical industry, high-temperature components in gas turbines like e.g. combustion chambers and casings. Processing properties: Formability: good Weldability: good |
