ABSTRACT:
A method for producing a multi-layer metal strip comprising at least one strip of a high-speed steel alloy which in addition to iron and normal impurities contains 0.60-1.30 % C, 3.0-5.0 % Cr, 1.0-10 % Mo, 1.0-20 % W, up to 12 % Co and 0.5-4.0 % V, and which is cemented onto a carrier strip by electron-beam welding. In order to attain a good flow of the molten metal in the gap between the high-speed steel strip and the carrier strip 0.005-0.5 % Ce is added to the high-speed steel alloy. Ce can be added as a "misch metal" and may then contain the lanthanides normally present in misch metal. The multi-layer metal strip thus produced is used in the manufacture of hacksaws.
