347/347H is an austenitic chromium steel containing columbium often used in refineries, high temperature chemical processing, and high temperature steam service. This columbium bearing steel not sensitive to intergranular corrosion after heating within the range of carbide precipitation but elevated properties may be achieved through cold reduction.
