Heat treatment process for iincoloy 800h:
1.Solution AnnealingIncoloy 800H is typically solution treated at temperatures ranging from approximately 1100°C to 1180°C, typically lasting 1-4 hours. The purpose of this step is to dissolve the intergranular packaging strengthening phase in the alloy so that it is evenly distributed in the grains.
2.Water Quenching**After solution treatment, Incoloy 800H usually requires rapid cooling (water quenching) to ensure grain uniformity and stability. After water quenching, the grain size can be effectively reduced, and the strength and heat resistance of the alloy can be improved.
3.AgingINGO® 800H after solution treatment and water quenching usually requires aging treatment, i.e., at a lower temperature (usually 700°C - 900°C) for a period of time to stabilize the precipitation of the intergranular packaging strengthening phase and improve the creep resistance and high-temperature strength of the alloy.
