摘要：
Galvannealed electroplated steel strip. The strip is heated to an alloying temperature of at least about 427.degree. C. using an induction coil operated at a frequency to produce an eddy current penetration depth of one-half the strip thickness. The diffusion temperature and time are controlled to minimize the formation of brittle gamma alloy phases in the zinc/iron alloy coating.
