Kub Rolled Strutural Steel Phaj Khoom Taw Qhia
Daim ntawv thov EN S355J2 EN 10025-2 qib steel yog siv rau ntau yam kev siv, suav nrog cov txuas hniav, cov tsev, siab- cov qauv nce, cov qauv sab nrauv, thiab ntau yam khoom siv engineering. Nws kuj tseem siv rau hauv kev tsim cov khoom siv tsheb, thiab hauv cov khoom siv xws li kev tsheb thiab kev tsheb ciav hlau, excavators, loaders, thiab khoom siv ua liaj ua teb.
Kub Rolled structural veseel steel phaj Khoom Paub meej
Carbon, Silicon, Manganese, Phosphorus, Sulfur yog cov ntsiab lus tseem ceeb hauv EN S355J2 EN 10025-2.
Cov pa roj carbon monoxide yog qhov tseem ceeb tshaj plaws hardening nyob rau hauv steel.
Silicon pab txhawb lub zog. Zoo li manganese, silicon yog siv los tswj lub zog ntawm cov hlau thaum lub sij hawm tsim cov hlau.
Manganese yog qhov tseem ceeb ntawm austenite stabilizing cov ntsiab lus pab txhawb kev tsim cov qauv kev ntxhib los mos thiab ua kom muaj zog, lub zog thiab hnav tsis kam.
Phosphorus yog ib qho teeb meem. Txo cov plasticity thiab toughness ntawm steel thiab tshwm txias brittleness. Nws tuaj yeem txhim kho lub zog ntawm cov hlau, thiab txhim kho cov atmospheric corrosion stability. Cov ntsiab lus yuav tsum txwv tsawg dua 0.05%.
Feem ntau cov sulfur yog ib qho teeb meem, uas ua rau kub brittleness ntawm steel siab, thiab cov ntsiab lus ntawm cov sulfur yog txwv tsis pub tsawg tshaj 0.05%.

EN S355J2 EN 10025-2 Mechanical Properties
Cov txiaj ntsig yog hais txog kev hloov pauv ntawm EN S355J2 EN 10025-2 los ntawm tsis yog-cov ntaub ntawv elastic lub xeev mus rau elastic- lub xeev yas tom qab ncav cuag ib qho kev nyuaj siab deformation. Nws cim qhov pib ntawm macro-yas deformation.
Tensile zog (Rm) yog hais txog qhov siab tshaj plaws uas EN S355J2 EN 10025-2 dais ua ntej tawg. Thaum cov hlau yields mus rau ib qho twg, nws tsis kam mus deformation nce ntxiv vim qhov rearrangement ntawm cov nplej. Nyob rau lub sijhawm no, txawm hais tias qhov deformation loj hlob sai, nws tsuas tuaj yeem nce nrog qhov nce ntawm kev ntxhov siab kom txog rau thaum qhov siab tshaj plaws tau mus txog. Tom qab ntawd, EN S355J2 EN 10025-2 muaj peev xwm tiv thaiv kev deformation yog pom tseeb txo qis, thiab cov yas loj deformation tshwm sim ntawm qhov tsis muaj zog tshaj plaws, qhov twg cov seem ntawm cov qauv me me zuj zus, ua rau caj dab kom txog thaum tawg. Tus nqi siab tshaj plaws ntawm EN S355J2 EN 10025-2 ua ntej tensile tawg yog hu ua lub zog txwv lossis lub zog tensile.
