Disclosed is a metallurgical vessel, in particular a converter for treating liquid molten metals, in particular steel, formed of a refractory lining and a supporting metal shell that surrounds the refractory lining. The vessel is composed of welded together shell rings and dished parts of creep-resistant steel with plate thicknesses of up to 100 mm. The creep-resistant steel used is a highly resistant, water-quenched and then tempered close-grained structural steel with the following composition in wt.-%C 0.14-0.22Cr 0.4-1.0Mo 0.3-0.8Ni 1.5-3.0V 0.05-0.12Mn 0.7-1.3Pmax 0.015Smax 0.003Al 0.015-0.065Si 0.20-0.60Cumax 0.15Nmax 0.012Camax 0.004the remainder being iron and impurities due to the production process.
