Abstract
The invention discloses an austenitic stainless steel bare welding wire for a sodium cooled fast reactor and application of the austenitic stainless steel bare welding wire, and belongs to the technical field of welding materials. The chemical components of the welding wire include, by weight, 0.03-0.08% of C, 18.0-20.0% of Cr, 11.5-13.5% of Ni, 2.00-2.60% of Mo, 0.04-0.08% of N, 1.40-2.40% of Mn,0.30-0.70% of Si and the balance iron and unavoidable impurities. The welding wire is suitable for welding of the sodium cooled fast reactor, and is small in splashing, stable in process and good intechnological property when welding is conducted. By adopting the stainless steel welding wire, a welding joint conforming to required properties can be obtained, and the stainless steel welding wirecan replace an imported welding wire.
Description
technical field [0001] The invention relates to the technical field of welding materials, in particular to an austenitic stainless steel light welding wire for sodium-cooled fast stacking and its application. The welding wire is applied to sodium-cooled fast stacking welding. Background technique [0002] The structure of the sodium-cooled fast reactor is welded by different components (such as inner and outer containers, support structures in the reactor, grid headers, core barrels, heat shields, etc.). Due to the large structure size and compact and complex design of the fast reactor, the welding process is complicated and the welding volume is large. During the operation of the fast reactor, the structural materials in the reactor are exposed to high temperature, high corrosion, and high radiation environment for a long time, and the working conditions are extremely harsh. The neutron dose borne by the inner support is about 1018n / cm 2 ; The neutron dose borne by the co...
