A carbon tool steel strip having a thickness of 1 mm or less and a carbon tool steel composition containing 0.8-1.2% C by mass %, wherein the carbon tool steel strip has a Vickers hardness of 500-650 (Hv), and when a cross-section at the center in the sheet thickness direction of the carbon tool steel strip is viewed with the plane of observation in a direction at a right angle to a rolled surface of the carbon tool steel strip and in the length direction of the carbon tool steel strip, the area ratio of carbides having an equivalent circle diameter of at least 0.5 ?m among the carbides present in the metallographic structure is 0.50-4.30%.

Abstract: The present invention relates to an Ag alloy film. Particularly, it is preferably used as a reflective film or semi-transmissive reflective film for an optical information recording medium having high thermal conductivity/high reflectance/high durability in the field of optical information recording media, an electromagnetic-shielding film excellent in Ag aggregation resistance, and an optical reflective film on the back of a reflection type liquid crystal display device, or the like. The Ag alloy film of the present invention comprises an Ag base alloy containing Bi and/or Sb in a total amount of 0.005 to 10% (in terms of at %). Further, the present invention relates to a sputtering target used for the deposition of such an Ag alloy film.

Abstract: The invention relates to sheet steel for use as packaging steel, made of a non-alloy or low-alloy and cold-rolled steel having a carbon content of less than 0.1%. According to the invention, in order to use such sheet steel for packaging steel that has good formability and can be produced in a cost-effective way, the sheet steel contains less than 0.4 wt % of manganese, less than 0.04 wt % of silicium, less than 0.1 wt % of aluminum, and less than 0.1 wt % of chromium and is provided with a multi-phase structure, comprising ferrite and at least one of the structure constituents martensite, bainite, and/or residual austenite. The invention further relates to a method for producing such packaging steel from cold-rolled sheet steel.

Abstract: A cast alloy is generally provided, along with methods of forming the cast alloy and components constructed from the cast alloy (e.g., stationary components of a turbine). The cast alloy can include, by weight, 0.12% to 0.20% carbon, 0.50% to 0.90% manganese, 0.25% to 0.60% silicon, 0.10% to 0.50% nickel, 1.15% to 1.50% chromium, 0.90% to 1.50% molybdenum, 0.70% to 0.80% vanadium, 0.0075% to 0.060% titanium, 0.008% to 0.012% boron, the balance iron, optionally low levels of other alloying constituents, and incidental impurities.
