The relationship between hot rolling parameters, annealing parameters, microstructures and stress corrosion cracking behavior of Ni-Cr-Fe Alloy 600 in deaerated primary plant grade water at 680{degrees}F was investigated. A high carbon (0.07%) and a medium carbon (0.04%) heat were hot rolled 20% or 80% starting at 3 different temperatures: below, near, and above the carbide solvus followed by annealing for 1 or 4 hours at a nominal temperature of 1600{degrees}F or 1900{degrees}F. Materials that are resistant to stress corrosion cracking were produced by hot rolling above the carbide solvus temperature followed by annealing at high temperatures (>1900{degrees}F). A combination of hot rolling below carbide solvus, large rolling reduction and a short annealing at a low temperature produced materials susceptible to stress corrosion cracking, especially for the high carbon heat. The resistant materials have by optical metallography as having carbide decorated grain boundaries, little intragranular carbide precipitation and good grainboundary correlation between a nital and a phosphoric acid etch. The susceptible materials as lack grain boundary carbide precipitation, have heavy intragranular carbide precipitation and lack grain boundary correlation between a nital and a phosphoric acid etch.
