The development of an advanced nickel base alloy with a higher total chromium + molybdenum + tungsten content than any previous nickel alloy is discussed. Production of this material, INCONEL* alloy 686 (UNS N06686 - 21% chromium, 16% molybdenum, 4% tungsten, 1% iron, balance nickel), is possible due to control of minor alloying elements and special processing techniques. The mechanical properties, pitting, crevice corrosion, general corrosion and intergran-ular corrosion
