Zusammenfassung:	PURPOSE:To suppress the formation of TiN on the surface layer part and to prevent the growth of scales by executing annealing treatment to a Ti-contg. Cr series stainless-hot rolled steel strip in an atmosphere of an H2 or H2 mixed gas. CONSTITUTION:At the time of annealing a Cr series stainless-hot rolled steel strip contg., by weight, 0.05 to 2.00% Ti, it is executed in an atmosphere of a 100vol.% H2 gas or an H2-N2-mixed gas in which the content of the N2 gas is regulated to
