EN 10095 NiCr20Ti Alloy – Solution Annealed (With AT)

NiCr20Ti is also contained as a aviation material (mat. No 2.4630) in material-performance specifications of the German Aviation WL 2.4630-1, -2, -3,-4, -100 : 1993-08 (Werkstoff-Leistungsblätter der Deutschen Luftfahrt WL). It is non-scaling up to approx. 1150 °C (highest application temperature in air) and shows high corrosion resistance and creep rupture strength up to 750°C as well as favorable resistance to thermal shocks. Application in carburizing or sulfureous furnace athmospheres is not advisable at higher temperatures. Use for components in gas turbines (rings, casing parts), parts for industrial furnace construction, palletts and boxes for component`s heat-treatment as well as for components in aerospace. Processing properties: formability: good weldability: good
