METHOD FOR IMPROVING THE WELDABILITY OF HIGH-MANGANESE-CONTAINING STEEL STRIPS AND COATED STEEL STRIP

摘要

In a method for improving the weldability of high-manganese-containing steel strips which contain (in % by weight) from 6 to 30% of manganese, up to 1% of carbon, up to 15% of aluminum, up to 6% of silicon, up to 6.5% of chromium, up to 4% of copper and also total additions of titanium and zirconium of up to 0.7% and total additions of niobium and vanadium of up to 0.5%, balance iron including unavoidable steel-accompanying elements the steel strips are coated with a zinc-containing corrosion protection layer.
