Abstract
PURPOSE: To eliminate the need for homogenizing treatment and obtain good cold workability by hot working an alloy steel controlled of N, Al, O to prescribed amts. under specific conditions.
CONSTITUTION: An alloy steel is controlled to 0.005W0.03% N, ≤0.005 O, and 0.01W0.1% Al. This alloy steel is heated to ≤1,070°C, and is hot-rolled by adding at least ≥15% reduction of area at 700W750°C temps. of finish working. Next, this hot-rolled alloy steel is cooled as it is down to 500°C at ≤5°C/sec cooling rates. The alloy steel obtained by the above-mentioned method does not require homogenizing treatment prior to cold working and is subjected to cold drawing or cold forging as it is as a blank material for working.
