S355J0H yog dab tsi?
S355J0H yog cov khoom siv qis carbon steel, uas yog cov khoom siv seamless steel yeeb nkab raws li European tus qauv EN10219-1. Nws cov tshuaj muaj pes tsawg leeg suav nrog cov ntsiab lus xws li carbon, silicon, manganese, sulfur thiab phosphorus. Ntawm lawv, cov ntsiab lus carbon tsis tshaj 0.22 feem pua, uas yog ib qho ntawm cov yam ntxwv tseem ceeb ntawm nws cov pa roj carbon tsawg. Cov ntaub ntawv tseem muaj cov lej ntawm cov ntsiab lus xws li tooj liab, chromium, npib tsib xee, thiab molybdenum, thiab cov khoom me me xws li txhuas thiab titanium. Cov ntsiab lus no tuaj yeem txhim kho cov khoom xws li lub zog, toughness thiab corrosion kuj ntawm steel.
S355J0H steel yeeb nkab muaj cov khoom siv kho tshuab zoo heev, lub zog tensile siab thiab lub zog tawm los, thiab zoo plasticity thiab cuam tshuam toughness. Tsis tas li ntawd, cov khoom siv kuj muaj cov khoom zoo xws li kev tiv thaiv corrosion thiab hnav tsis kam, thiab tsim nyog rau kev siv hauv ntau yam qauv thiab cov khoom siv kho tshuab.
S355J0H steel kav yog dav siv nyob rau hauv kev tsim kho, txuas hniav, roj pipelines, natural gas pipelines, automotive manufacturing, machinery manufacturing, marine engineering and other fields. Lawv tuaj yeem siv los tsim ntau hom qauv thiab khoom siv xws li brackets, trusses, platforms, kav, txuas hniav, cranes, excavators, tsheb chassis, thiab lwm yam.
Hauv luv luv, S355J0H cov khoom siv yog cov khoom siv zoo seamless steel yeeb nkab khoom nrog cov khoom siv kho tshuab zoo thiab ntau yam khoom zoo heev, thiab tuaj yeem siv dav hauv ntau yam qauv thiab tshuab.
