<P>PROBLEM TO BE SOLVED: To improve a durable temperature to 760-800°C while maintaining hot workability. <P>SOLUTION: A Ni-based forging alloy contains: 0.001-0.1 wt.% of C; 12-23 wt.% of Cr; 3.5-5.0 wt.% of Al; and inevitable impurities, and the balance comprises Ni. The sum of W and Mo is 5-12 wt.%; the Mo is 5 wt.% or less; and the added amount of Ti, Ta and Nb is practically zero. <P>COPYRIGHT: (C)2012,JPO&INPIT |
