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.

摘要： A process for controlling zinc vapor in a finishing process for a hot dip zinc based coating on a ferrous base metal strip in which the strip emerges from the coating bath into an enclosed chamber, by injecting high dew point gas into the chamber. The process is applicable on both a one side and two side coating process. Preferably the atmosphere has about 1-3% water vapor, by volume, for both one-sided and two-sided process.
