Alloy B-3 Description
Alloy B-3 is a nickel- molybdenum alloy with excellent resistance to pitting, corrosion and stress-corrosion cracking, plus thermal stability superior to that of alloy B-2. This alloy has also great resistance to knife-line and heat-affected zone attack. The improved thermal stability of B-3 alloy minimizes the problems associated with fabrication of B-2 alloy components. This is due to the reduced tendency to precipitate deleterious inter-metallic phases in B-3 alloy , thereby, affording it greater ductility than B-2 alloy during and following various thermal cycling conditions.
