ER347 (a Titanium stabilised) filler metal that mitigates sensitization and suitable for we;ding 321Hdue to its similar composition and properties.Minimise the heat input to reduce the time spent in the sensitization temp. range (427 to 871 deg.C).Avoid preheating. Titanium forms titanium carbides and preserves chromium levels and maintainscorrosion resistance at high temperatures.Sridhar.--On Fri, 24 Jan 2025 at 22:28, Ch Bilal jovinda <chbilaleng1989@gmail.com> wrote:--Dear Experts,
I seek your guidance on the following query:
When welding SS 312 TP 321H material using the GTAW process with ERNiCrMo-3 filler metal, what are the major safety precautions required to control the cooling rate to avoide sensitization?
Your valuable insights will be highly appreciated.
