Material Description

Material Number Material Number (single) Standard Standard Status Country VDA 231-106 classification Application temperature [°C]
1.4943 (WL 1.4943 : 1992-08) 1.4943 WL 1.4943 : 1992-08 Valid Germany 1.1 ≤ 700 1)
1) Remark: The high-strength stainless nickel-chromium-titanium aerospace steel is scale resistant up to about 725 °C. It's weldable and primarily used for gas turbine parts to be welded, in particular after-burner and nozzle casing parts up to approx. 700 °C. The strength properties at elevated and low temperatures, including the long-time values and the fatigue strength are similar to 1.4944. The corrosion resistance is comparable with 18/8 chromium-nickel stainless steels. There is resistance to all atmospheric influences up to 725 °C, occurring with the turbine engine. The steel is resistant to stress corrosion.
