METHOD FOR PRODUCING HIGH-SPEED TOOL STEEL MATERIAL, METHOD FOR PRODUCING HIGH-SPEED TOOL STEEL PRODUCT, AND HIGH-SPEED TOOL STEEL PRODUCT |
摘要 |
Provided are: a method for producing a high-speed tool steel material capable of increasing carbides in the structure of a high-speed tool steel product; a method for producing a high-speed tool steel product; and a high-speed tool steel product. The method for producing a high-speed tool steel material is provided with: a casting step for casting molten steel to obtain a steel ingot; a blooming step for heating the steel ingot obtained in said casting step to a temperature exceeding 1120°C and thereafter hot-working same to obtain an intermediate material; and a finishing step for heating the intermediate material obtained in the blooming step to a temperature of 900-1120°C and thereafter hot-working same to obtain the high-speed tool steel material. Further, said method for producing a high-speed tool steel material is provided with an annealing step for annealing the high-speed tool steel material obtained in said finishing step. The present invention is also: a method for producing a high-speed tool steel product, wherein quenching and annealing is performed on the high-speed tool steel material obtained in the production method above; and a high-speed tool steel product. |
