A near alpha, high temperature creep resistant alloy that may be used up to 1400°F (760°C) in certain applications. It has a high combination of strength, creep resistance, fracture toughness and fatigue crack growth resistance. It is primarily used in the beta processed (beta worked or beta annealed) condition. A main application for this alloy is automotive/motorcycle engine valves. Mechanical property data for samples after Beta Anneal + 1400°F (760°C)/1hr treatment. Data provided by TIMET. |
