Abstract
The ferrite stainless steel welding rod of this invention comprises the following: 0.03% by weight or less of carbon, 1.00% by weight or less of silicon, 1.00% by weight or less of manganese, from 16.0 to 21.0% by weight of chromium, from 0.30 to 0.80% by weight of niobium, from 0.30 to 0.80% by weight of copper, 0.025% by weight or less of nitrogen, and the balance of iron. The ferrite stainless steel welding rod of this invention offers a good weldability not only in welding stainless steels of the same type but also in welding stainless steels of different types. Further, the welding steel of this invention has a good oxidation resistance, and a good workability and mechanical property.
