ABSTRACT:
A chromium weld material comprising chromium as a main component and either one of or an appropriate combination of elements selected from the group IVb metals of the periodic table, Al, metals belonging to the groups VIIb, VIII, and Ib of the periodic table, Nb, and Ta and, if desired, at least one of rare earth elements, a chromium rolled article comprising chromium as a main component and either one of or an appropriate combination of elements selected from Al, Ti, Zr, Hf, Y, rare earth elements, and elements belonging to the groups Vb, VIb, and VIIb of the periodic table, and a process for producing said rolled article by cross-rolling under specific temperature and output rate conditions are disclosed. The weld material provides a weld free from deterioration of mechanical characteristics. The rolled article exhibits excellent tensile characteristics. The process provides a rolled sheet of small thickness without causing craking.
