Behaviour of nitrogen-strengthened stainless steel welded assemblies : Part II : Austenitic-ferritic steelFunded under: ECSC-STEELRES 8C
The aim of this research was to quantify the effects of nitrogen and manganese alloying on the welding behaviour of austeno-ferritic steels containing 22% chromium and 3% molybdenum. Single pass coated electrode deposits, multi-pass submerged arc welded joints and electron beam welded joints were prepared from four compositions of 20 mm thick sheet steel and by use of experimental filler wires. After estimating technical weldability, the welded materials (parent metals, heat-affected zones and weld metal) were studied with regard to microstructure, mechanical properties and resistance to different kinds of corrosion. The addition of up to 0.29% nitrogen and up to 8% manganese to these parent metals did not impair technical weldability either by submerged arc or by electron beam.
