ABSTRACT:
A highly corrosion resistant, durable, strong, hardenable and relatively inexpensive nickel based alloy containing chromium and a high iron content has improved castability and weldability. The alloy contains approximately the quantities indicated: nickel 33 to 53 (to balance to 100 percent), chromium 20 to 25 percent, molybdenum 6 to 9 percent, cobalt 4 to 8 percent, iron 15 to 20 percent, manganese 2 to 4 percent, copper less then about 0.15 percent, carbon up to 0.2 percent and silicon 0.5 to 1.0 percent. The alloy is air meltable and produces a highly fluid castable melt. All percentages are by weight.
