Abstract
Weldability test results made on Cb containing austenitic stainless clad steel, named Remanit 1880SS, have clarified the following points.
(1) A mild steel electrode of low hydrogen type proved to be best in welding the mild steel side of the plate.
(2) The lower layer of the stainless steel side should first be welded with 25 Cr-20 Ni steel electrodes, and then the upper layer be filled with 19 Cr-12 Ni-Mo-Cb stainless rods having a similar composition to the clad metal.
(3) No appreciable difference was found in corrosion resistivity, between the specimens as welded and those after given cold-works such as bending or rolling.
(4) Excessive cold working on stainless steel weldment should be avoided, because they are easily hardened due to the formation of martensite in addition to the work-hardening.
(5) Martensitic structure disappears by annealing at temperatures above 1000°C.
