Abstract
A welded structural member adapted to be subjected to a flowing fluid and comprising a base member consisting mainly of iron and a coating layer formed by a build-up welding on the surface of the base member, the coating layer having a higher erosion resistance than the base member. The coating layer contains 0.03 to 0.4 wt % of C, 0.1 to 1 wt % of Si, 0.5 to 20 wt % of Mn, 1 to 5.5 wt %, of Ni, 1 to 12 wt % of Co, 8 to 23 wt % of Cr and the balance Fe. The structure of the coating layer is mainly unstable austenite.
