Abstract

An iron alloy material for casting includes 0.3 to 3.5 mass % of C, 0.1 to 3.0 mass % of Si, 26.0 to 42.0 mass % of Ni, 0.02 to 0.50 mass % of Sb, and a balance that is Fe and an inevitable impurity/impurities.

Claims (1)

1 . An iron alloy material for casting that consists of 0.7 to 3.5 mass % of C, 0.1 to 3.0 mass % of Si, 26.0 to 42.0 mass % of Ni, 0.02 to 0.50 mass % of Sb, 0.001 to 6.0 mass % of Co, 0.01 to 1.4 mass % of Mn, 0.01 to 0.1 mass % of Mg, and a balance that is Fe and inevitable elements, wherein the inevitable elements include Mo and Al, and a total of contents of the inevitable elements is 1.0 mass % or less.
