摘要： A method for warm forging a cup-shaped piece is disclosed. In warm forging a blank is heated between 400 and 800.degree.C and is inserted within a die having a cross sectional area substantially larger than that of the blank. The ends of the blank are clamped between a recess in the die and a recess in an upsetting punch and the upsetting punch compresses the blank until its sides become sufficiently bulged to almost touch, or touch, the sides of the die. The upsetting punch is then removed and a backward extruding punch is press fitted into the bulged blank and the blank is extruded to form a cup. The extrusion punch is lubricated and cooled by lubricant and coolant applicators at a position remote from the die so that the blank is not prematurely cooled by the coolant.

摘要： A steel for a high-specularity plastic die is a steel material containing 0.20 to 0.50 mass% of C and 10.50 to 20.00 mass% of Cr. When carbide-dense regions in the steel material, the grain size of carbides constituting the dense regions being not less than 5 ?m by projected area diameter, the distance between carbides being no more than 30 ?m, and the area of the carbide-dense regions being no less than 1000 ?m2 are designated as material grains, the maximum length of the material grains is not more than 1000 ?m and the area ratio of the material grains is not more than 2.0%. Thus, specularity can be improved by regulating the size of material grains associated with the carbidedense regions.

摘要： [Object] To provide a wire 1 for piston rings which is less likely to cause a width of an end gap 4 of a piston ring to be varied, is excellent in processability during coiling, and is obtained at low cost. [Solution] The wire 1 for piston rings is made of steel which contains 0.50% by weight or greater but 0.80% by weight or less of C, 1.00% by weight or less of Si, 1.00% by weight or less of Mn, 11.0% by weight or greater but 14.0% by weight or less of Cr, 0.20% by weight or greater but 2.0% by weight or less of Mo, and an unavoidable impurity. An area ratio of carbide particles having a circle-equivalent diameter of 0.2 μm or greater but 5 μm or less in a structure in a transverse section of the wire 1 is equal to or less than 10%. A Vickers hardness of the wire 1 is equal to or greater than 350 but equal to or less than 450. The wire 1 is obtained through quenching and tempering. A temperature of the tempering is equal to or higher than 645°C.
