Abstract:
The Ni-based alloy exhibits superior grain boundary corrosion resistance including C: 0.005 to 0.03 mass %, Si: 0.02 to 1 mass %, Mn: 0.02 to 1 mass %, P: not more than 0.03 mass %, S: not more than 0.005 mass %, Cr: 18 to 24 mass %, Mo: 8 to 10 mass %, Nb: 2.5 to 5.0 mass %, Al: 0.05 to 0.4 mass %, Ti: not more than 1 mass %, Fe: not more than 5 mass %, N: not more than 0.02 mass %, and Ni as a remainder and inevitable impurities. The C concentration range, the ratio of (Nb, Ti) C carbides to all carbides is not less than 90%, and the number of (Nb, Ti) C carbides satisfies the following formula: −30×T+37220=<number of (Nb, Ti) C carbides (number/mm 2 )=<−7.7×T 2 +15700×T−7866000 under a condition of 2000×% C+890=<T(temperature ° C.)=<1150.

Claim (Index 3):
The Ni-based alloy according to  claim 1 ,\n wherein corrosion rate in ASTM G28 Method A test is less than 1.5 mm/y.
