Title:
PRODUCTION OF FORGED PRODUCT
Document Type and Number:
Japanese Patent JP3435906
Kind Code:
B2
Abstract:
PURPOSE: To improve the mechanical property more and more because the effect of forging can sufficiently be obtd. and also, to improve the surface quality more and more by strong pressure.
CONSTITUTION: At the time of forming a forged product having a desired shape by forging a blank for forging after forming the blank for forging by casting, the blank for forging having non-similar shape to the desired shape of the forged product 2 so as the obtain at least either one or 15% forging ratio or ≥50MPa stress in the main position in the desired shape of the forged product 2 obtd. by forging. Thereafter, the blank for forging is formed to the desired shape of the forged product 2 to obtain at least either one of 15% forging ratio or ≥50MPa stress in the main position in the forged product 2.
