Partially alloyed galvanize product |
摘要 |
A partially alloyed galvanized ferrous strand and a method for its production. The method is characterized by the steps of immersing a clean and oxide-free ferrous strand in a molten zinc galvanizing bath to produce on the strand a coating weight of between 0.2 and 0.5 oz. per square foot. After immersion, the zinc-coated ferrous strand is heat treated and cooled to produce a galvanized coating on said ferrous strand, which coating has a duplex structure characterized by an iron-zinc intermetallic layer consisting essentially of the zeta phase, an overlay of free zinc, and an average iron content between about 2 and less than 4% by weight.
