Abstract
A method of coating dual phase high strength cold rolled steel having controlled amounts of carbon, manganese, and molybdenum is used as a starting material in a galvanizing/galvannealing process. Conditions in a multi-zone furnace of the galvanizing line can be controlled in a conventional manner while still effectively coating the high strength steel. A dual phase high strength steel product is made having a uniform coating of zinc in spite of the high manganese content of the steel.
