Özet

 Ferritic stainless steel type EN 10088: X2CrNi12 is known as a low cost stainless steel grade exhibiting good corrosion and abrasion resistance. Common applications for this type of stainless steel are bus frames and chassis, railway wagons for coal and iron ore, mining and mineral processing, etc…The modern production routes allow fabricating this steel grade with a low carbon content (<0.015% C) and low impurity levels improving the weldability substantially. Regarding to these conditions, this 12Cr stainless steel becomes an attractive steel that could replace structural steel grades such as EN 10025: S355. In this paper, 12mm thick X2CrNi12 stainless steel plates were welded using SMAW, GMAW, SAW and LASER processes in order to investigate mechanical and microstructural properties respectively. Promising results have been obtained. Interesting correlations were found between microstructure (e.g. grain size) and impact toughness.
