    摘要: There is provided a spot-weldable bonded clad metal plate wherein the metal sheets are 0.05-1.0 mm thick and at least 0.4 mm thick, respectively, the adhesive layer has a thickness of 15-60 microns and the adhesive layer contains 10-100 g/m.sup.2 of metallic powder having a particle diameter corresponding to 0.5-1.5 times the thickness of the adhesive layer. The metallic powder is not necessarily entirely metallic and, for example, glass beads having surfaces coated with a metal can also be used. As the adhesive, a polyamide resin adhesive, particularly, a hot melt type polyamide resin adhesive is preferred.The bonded clad metal plate shows excellent adhesion strength, and in spite of such thin metal sheets, does not blister when spot-welded.

    摘要: High chromium steel, for use at high temperature, of a mixed structure containing ferrite and 0.02-0.09% C, less than 1.0% Si, 0.1-2.0% Mn, 7.0-13.0% chromium, 1.2-3.0% Mo, and the rest being iron and the usual impurities, or further adding aluminum in an amount less than 0.1% to said composition, or further adding 0.001-0.1% boron and less than 0.1% Ti necessary to cause the boron to act effectively, said steel being heated at temperatures lower than about 1050.degree. C. to prevent the oxidation of the steel.
