摘要： A method is proposed for the production of high-strength low-expansion cast iron enabled to acquire improved strength, hardness, and cutting workability while retaining the property of low expansion intact. The product is a low-expansion cast iron having a high nickel content and exhibiting a coefficient of thermal expansion of not more than 8.times.10.sup.-6 /.degree. C. at temperatures in the range of from room temperature to 100.degree. C. By causing a carbide to be finely precipitated in an area ratio in the range of from 0.3% to 20% in the metal structure of the cast iron and lowering the C content in the cast iron, there is produced a high-strength low-expansion cast iron. The deposition of the carbide mentioned above is accomplished by incorporating in the material for cast iron at least one element selected from the group consisting of the transition metal elements of IVa, Va, and VIa Groups in the Periodic Table of the Elements.
