High Strength Hot Dip Galvanized Steel Plate Having Excellent Impact Resistance And Method For Producing Same And High Strength Alloyed Hot Dip Galvanized Steel Sheet And Method For Producing Same
Abstract: 12162This base steel sheet has a hot dip galvanized layer formed on the surface and the volume fraction of a retained austenite phase of the steel sheet structure in a range of 1/8 of the sheet thickness to 3/8 of the sheet thickness centered around 1/4 of the sheet thickness from the surface is not more than 5% and the total volume fraction of a bainite phase a bainitic ferrite phase a fresh martensite phase and a tempered martensite phase is not less than 40%. The average effective grain size is not more than 5.0 µm and the maximum effective grain size is not more than 20 µm. A decarburized layer with a thickness of 0.01 to 10.0 µm is formed on a surface section the density of oxides which are dispersed in the decarburized layer is 1.0 × 10 to 1.0 × 10 oxides/m and the average particle size of the oxides is not more than 500 nm.
