Assembly device of tubes in low carbon ferritic stainless steel having 17 to 18.5% by weight of chromium on a tube-plate of carbon steel. It includes at least one overlay of low carbon steel on the surface of the tube-plate opposite the plurality of tubes, of such thickness that the ends of the tubes are located at an intermediate level of the overlay, and weld beads between the ends of the tubes and the overlay.

Assembly device of ferritic stainless steel tubes on a carbon

Assembly device of tubes of low carbon ferritic stainless steel having 17 to 18.5% by weight of chromium on a tube-plate of carbon steel. It includes a first overlay of low carbon austenitic stainless steel having 11.50 to 14% by weight of nickel and 22 to 25% by weight of chromium on the surface of the tube-plate opposite the plurality of tubes, a second overlay on the first of low carbon austenitic stainless steel having 10 to 12% by weight of nickel and 19 to 23% by weight of chromium extending beyond the upper level of the ends of the tubes, and weld beads with or without filling metal around these ends between these ends and the stainless steel of the second overlay.
