Stainless-clad　bimetallic　steel　is　increasingly　recognized　for　its　structural　applications　due　to　its　cost-effectiveness　and　high　corrosion　resistance.　Butt　weld　connections　are　essential　in　engineering,　playing　a　pivotal　role　for　maintaining　structural　integrity.　However,　the　post-fire　mechanical　properties　of　stainless-clad　bimetallic　steel　butt　welds　have　not　been　investigated　to　date.　This　paper　presents　an　experimental　investigation　into　the　post-fire　mechanical　properties　of　stainless-clad　bimetallic　steel　butt　welds,　focusing　on　a　range　of　exposure　temperatures　from　room　temperature　to　1000　°C,　and　cooling　methods　including　cooling　in　air　(CIA)　and　cooling　in　water　(CIW).　Tensile　failure　modes,　stress-strain　curves,　yield　strength,　ultimate　tensile　strength,　and　ductility　were　examined.　The　results　indicate　that　for　specimens　cooled　in　air　and　cooled　in　water,　both　the　yield　strength　and　ultimate　tensile　strength　are　comparable　to　those　measured　at　room　temperature　for　exposures　up　to　500　°C.　Beyond　this　temperature,　a　decline　in　strength　was　observed　for　specimens　cooled　in　air,　while　those　cooled　in　water　showed　a　significant　increase　in　both　yield　and　ultimate　tensile　strength　at　exposure　temperatures　exceeding　700　°C.　The　retention　mechanical　properties　(i.e.,　yield　strength　and　ultimate　tensile　strength)　of　stainless-clad　bimetallic　steel　butt　weld　coupon　specimens　exposed　to　elevated　temperatures　were　compared　with　those　of　mild　steel,　stainless　steel,　and　other　stainless-clad　bimetallic　steels,　demonstrating　significant　variations　in　their　responses　to　high　temperatures.　As　a　result,　the　predictive　equations　for　the　post-fire　yield　strength　and　ultimate　tensile　strength　of　stainless-clad　bimetallic　steel　butt　welds　were　developed,　considering　different　cooling　methods.　©　2024　Elsevier　Ltd
