    Abstract

    A series of iron-nickel-chromium alloys has been studied for the Alloy Casting Institute with reference to their resistance to corrosion in air at temperatures of 1600, 1800, 2000, and 2200 F. Most of the cast-alloy materials used in this investigation were prepared by the Research Laboratory of the American Brake Shoe Co. The chromium variation has been from 11 to 36 per cent at 5 per cent intervals, and the nickel content was varied from zero to approximately 70 per cent at the 11 per cent chromium level and from zero to about 50 per cent at the 31 per cent chromium level. For the most part, the carbon content has been about 0.45 per cent, but higher and lower carbon contents have been introduced to study the effect of carbon on certain compositions. The silicon and manganese contents have approximated 1.25 and 0.75 per cent, respectively. However, silicon, too, has been varied in certain compositions to study its effect on corrosion resistance. There has been substantial variation in the nitrogen content, but this element was not intentionally varied, and no study has been made of its effect on corrosion resistance.
