S355JR siab zog phaj kev ua tau zoo
S355JR siab zog steel phaj yog ib qho tsis tshua muaj alloy siab zog steel qauv uas ua tau raws li European tus qauv EN 10025. Nws tuav txoj haujlwm tseem ceeb hauv kev lag luam thoob ntiaj teb thiab kev tsim kho kev lag luam vim nws qhov kev ua tau zoo heev thiab kev siv dav dav.
S355JR low alloy structural steel muaj lub zog tensile siab thiab tawm los piv, thiab tuaj yeem tiv taus ntau yam kev thauj khoom thiab kev ntxhov siab. S355JR siab zog alloy hlau tuaj yeem tswj nws cov duab thiab kev ua tau zoo thaum raug cuam tshuam los yog kev vibration, thiab nws cov kev cuam tshuam toughness ntawm 20 degree tuaj yeem ncav cuag 27J, uas yog tsim rau siv nyob rau hauv qhov chaw txias.
Daim ntawv thov teb ntawm S355JR qis alloy steel phaj
Mechanical teb: Nws yog dav siv nyob rau hauv kev tsim cov qauv ntawm ntau yam hnyav machinery thiab khoom siv, xws li tsheb laij teb, harvesters, thiab lwm yam.
Tsheb teb: Hauv kev tsim cov tsheb xws li tsheb, tsheb ciav hlau, thiab tsheb thauj khoom, nws yog siv rau kev tsim cov chassis, thav duab thiab lwm yam khoom.
Lwm qhov chaw: Nws kuj tau siv dav hauv ntau qhov chaw xws li cov khoom siv petrochemical, cov hlab ntsha siab, thiab cov kav dej.
