Is superior in the slidability the alloy melting galvanized steel sheet

摘要

PROBLEM TO BE SOLVED: To provide a galvannealed steel sheet excellent in slidability. ;SOLUTION: On the surface of the galvannealed layer, crystals consisting essentially of Ti and Al are recognized at ≥5 pieces/mm² of 2-10 μm dimension of one side thereof. In this galvannealed layer, it is desirable to contain ≥0.001 wt.% Ti and ≥0.05 wt.% Al and further, ≥5 wt.% Fe.;COPYRIGHT: (C)1999,JPO
