The present invention provides a titanium sheet covered with a protective film superior in high temperature oxidation resistance and high temperature salt damage resistance and a method of production of the same and an automobile exhaust system using the same. The titanium sheet covered with a protective film is formed on its surface with a protective film of a thickness of 1 to 100 μm where flake-shaped metal Al with an average thickness of 0.1 to 5 μm and average width or average length of 1 to 50 μm or grain-shaped metal Al with an average size of 0.1 to 30 μm is dispersed in 20 to 60 mass % silicone resin or silicone grease and comprised of Si: 15 to 55 mass % and C: 10 to 45 mass % and having a balance of unavoidable impurities. Preferably the titanium sheet of the substrate contains one or both of 0.5 to 2.1 mass % of Cu and 0.4 to 2.5 mass % of Al. The method of production is to brush or spray the above composition of a silicone resin on a titanium sheet to form a protective film and heat it at 150 to 300° C. for 5 to 60 minutes.

The present invention provides a titanium material for hot rolling which enables reduction of defects on the surface (in the case of a flat material or strip coil, including not only the flat surfaces but also the side surfaces and edges) due to hot rolling. The titanium material for hot rolling has dimples imparted by cold plastic deformation whose mean value of the heights (Wc) of the undulation profile elements is 0.2 to 1.5 mm and mean value of the lengths (WSm) thereof is 3 to 15 mm. The invention also provides a method of producing the titanium material and a method of hot rolling the titanium material.
