Try some Inconel 600, if you're having temperature/oxidation/corrosion/abrasion problems; it's an austenitic nickel-chromium alloy (with a little iron, manganese, and copper thrown in). Used for things like gas turbine blades, it'll stand up to nearly anything you throw at it, even if you throw everything at it all at once. Prices might be high, but for critical pieces of kit like an injector nozzle, it might be just the thing you need.
Heck, if it's good enough for a nuclear reactor, it's good enough for anything else.
