The　recent　successful　mass　production　of　S32001　has　led　to　numerous　engineering　applications;　however,　there　are　limited　studies　specific　to　this　grade.　This　study　investigates　its　mechanical　performance　compared　to　traditional　duplex　stainless　steel　S32205　and　carbon　steel　Q355,　with　special　focus　on　anisotropy,　cold-forming　hardening,　and　welding　characteristics.　Experimental　results　show　that　S32001　has　a　dual-phase　microstructure　with　balanced　austenite　and　ferrite,　offering　competitive　strength　and　improved　plasticity　over　S32205.　It　exhibits　anisotropic　yield　strength,　a　pronounced　cold-forming　effect　enhancing　strength　but　reducing　ductility,　and　comparable　welding　performance　to　S32205,　with　a　distinct　heat-affected　zone.　Modifications　to　existing　constitutive　models　were　made　to　improve　the　prediction　of　stress-strain　behaviour　in　both　flat　and　cold-formed　regions.　Lastly,　a　life　cycle　cost　(LCC)　study　confirms　S32001＇s　cost-effectiveness　in　less　corrosive　environments.　©　2025　Elsevier　Ltd
