摘要： A predetermined steel containing Te: 0.0005 mass% to 0.0050 mass% is heated to 1320°C or lower to be subjected to hot rolling, and is subjected to annealing, cold rolling, decarburization annealing, and nitridation annealing, and thereby a decarburized nitrided steel sheet is obtained. Further, an annealing separating agent is applied on the surface of the decarburized nitrided steel sheet and finish annealing is performed, and thereby a glass coating film is formed. The N content of the decarburized nitrided steel sheet is set to 0.0150 mass% to 0.0250 mass% and the relationship of 2 × [Te] + [N] ≦ 0.0300 mass% is set to be established. Note that [Te] represents the Te content and [N] represents the N content.

摘要： A method for the hot working of a Cr-containing steel, which comprises holding a newly formed surface of the Cr-containing steel in a steam atmosphere, to thereby form an oxidized scale containing FeO, and then carrying out a subsequent hot working. More specifically, a method for producing a seamless steal pipe which comprises supplying a moisture to the inside of a raw hollow pipe prepared by piercing, to hold the newly formed inner surface of the raw hollow pipe in a steam atmosphere and thereby form an oxidized scale containing FeO, and then carrying out the subsequent drawing. The method allows, by the use of a simple and easy operation method and a simple device, the reduction of the surface defects being caused after a hot working, resulting in markedly prolonging the life of a tool used therein, which contributes greatly to the efficient production of a Cr-containing steel containing 5 to 18 % of Cr being in increasing demand.

摘要： A slab having a predetermined composition is heated to 1280°C or more. The slab is hot-rolled to obtain a hot-rolled steel sheet. The hot-rolled steel sheet is annealed to obtain an annealed steel sheet. The annealed steel sheet is cold-rolled to obtain a cold-rolled steel sheet. The cold-rolled steel sheet is decarburization annealed to obtain a decarburization annealed steel sheet. The decarburization annealed steel sheet is coiled in a coil state. The coil-state decarburization annealed steel sheet is finish-annealed. The cold-rolled steel sheet is heated to a temperature of 800°C or more at a rate of 30°C/sec or more and 100°C/sec or less during increasing temperature of the cold-rolled steel sheet in the decarburization annealing or before the decarburization annealing. The decarburization annealed steel sheet is heated at a rate of 20°C/h or less within a temperature range of 750°C or more and 1150°C or less during increasing temperature of the decarburization annealed steel sheet in the finish annealing.
