Q295GNH steel khoom Taw qhia
Weathering steel, feem ntau raug xa mus los ntawm cov khoom lag luam genericized COR-TEN steel thiab qee zaum sau tsis muaj hyphen li corten steel, yog ib pab pawg ntawm cov hlau alloys uas tau tsim los tshem tawm qhov xav tau ntawm kev pleev xim, thiab tsim kom muaj qhov ruaj khov zoo li xeb yog tias raug. rau huab cua rau ntau xyoo.
US Steel tuav lub npe lag luam ntawm lub npe COR-TEN. Lub npe COR-TEN yog hais txog ob qhov sib txawv ntawm cov hlau no: corrosion kuj thiab tensile lub zog. Txawm hais tias USS tau muag nws cov phaj lag luam rau International Steel Group (tam sim no Arcelor-Mittal) hauv xyoo 2003, nws tseem muag COR-TEN cov khoom muaj npe nyob rau hauv strip-mill phaj thiab daim ntawv foos.
Thawj COR-TEN tau txais tus qauv tsim A 242 (COR-TEN A) los ntawm ASTM International cov qauv pawg pawg. Cov qib ASTM tshiab dua yog A 588 (COR-TEN B) thiab A 606 rau cov ntawv nyias. Tag nrho cov alloys yog nyob rau hauv kev tsim thiab siv.
