Alloy 699 XA is a new alloy, which was developed for application in petrochemical industry under metal dusting conditions at high pressure. It contains 30% chromium and 2% aluminum. Due to this it showed a remarkable larger time to first pit in comparison to N06025 and N06690 in an examination in the highly carburization metal dusting gas 37% CO, 9% H2O, 7% CO2, 46% H2, at 600 °C at 20 bar. Strength properties and creep properties are similar or better than N06601. Ductility at room temperature is comparable to N06601. The Charpy V-notch impact energy and the elongation in a tensile test at 600°C are still above the lower limits after aging solution annealed samples for 3000 h at 600°C. Welding procedure test according to DIN EN ISO 15614-1 was successfully done on 16 mm plate with a matching filler metal. Alloy 699 XA has been produced as plate, bar, seamless tube and wire.

Key words: Alloy 699 XA, metal dusting, creep strength, ductility at room temperature, V- notch impact energy, welding, plate, bar, tube, wire
