Find Way to Halt Cast Iron's 'Growth'
Chicago, Sept. 22. (AP).—Cast iron that "grows" is one of the vexations of industry which the American society for steel treating believes has been corrected.
J. B. Vanick and Paul D. Merica reported to the society's convention today that a way had been found to stunt the growth of iron.
Cast iron "grows," they explained because of changes in the material's chemical composition induced by intermittent heat.
Three methods within year.
An alloy of nickel, copper and chromium has been developed, the metallurgists reported to present.
