Impact Behavior of Large SF590A Forged Product
SF 590A 대형 단조품의 충격특성에 관한 연구

Abstract
Impact behavior of large SF590A (Fe-0.65C-1.5Mn-0.035P-0.035S-0.3Cr-0.15Mo-0.4Ni-0.3Cu) forged propeller shaft was studied in this study. Charpy impact specimens were prepared from the forged product with different heat number. The impact value of each specimen with different heat number tends to vary greatly depending on the prior austenite grain size and, less significantly, on the amount of sulfur. The dominant metallurgical factors affecting impact behavior of SF590A forged product are discussed based on fractographic and metallographic observations.
