Influence of Hot Forming Parameters on the Corrosion Resistance of C-276 Alloy

The influences of forging temperature and heat treatment temperature and time on the corrosion resistance of C-276 alloy were investigated and results showed that the main influencing factor was precipitated u phase. On the base of the results and avoiding the precipitation of u phase, the hot forming parameters of C-276 alloy were confirmed, and the hot forming experiment was conducted. The testing results showed that the best corrosion resistance was obtained under the parameters determined.
