A high strength dual phase cold rolled steel having controlled amounts of carbon, manganese, and molybdenum is used as a starting material in a hot-dip zinc coating process to manufacture a high strength dual phase cold rolled steel having a conventional galvanized or galvannealed coating applied to at least one surface thereof, the zinc coated steel product having a uniform coating of zinc in spite of the high manganese content of the steel.

Coated steel alloy product

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.
