ST52-3 yog acarbon-manganese siab-yield steel qauvraws liDIN 17100 tus qauv. Nws yog ib qho tsis yog- alloy, dav dav engineering steel nrog lub zog zoo, weldability thiab txias- tsim cov khoom.
Qib no muaj aYam tsawg kawg nkaus tawm lub zog ntawm 355 MPa, uas siab dua li cov pa roj carbon zoo tib yam xws li S235 lossis S355. ST52-3 feem ntau yog xa hauvnormalized (N)mob kom ruaj khov mechanical zog thiab cov qauv zoo ib yam.
Nws ntaqis carbon sib npaug, ua kom yooj yim rau vuam yam tsis muaj preheating feem ntau. Nws kuj ua tau zoo hauv kev khoov, machining thiab sib sau.
ST52-3 yog siv dav hauvmachinery lug, steel lug, bases, thav duab, cranes, tsheb thauj khoom, khoom sivthiab lwm yam engineering Cheebtsam.
Qib no yogsib npaug rau S355JR / S355J2Hauv European tus qauv EN 10025 thiab tuaj yeem hloov tau los ntawm lawv ncaj qha.

1, Dab tsi yog qhov kev xa khoom rau ST52-3? Qhov txawv ntawm N thiab kub dov (AR) yog dab tsi?
Teb: Cov xwm txheej xa khoom:
AR Kub- dov: Thawj dov mob, tus nqi qis
N Normalized: Cua sov thiab tom qab ntawd cua-txias, ua rau muaj kev sib txuam ntau dua, kev ua haujlwm ruaj khov dua, thiab muaj kev cuam tshuam zoo dua. Rau cov khoom siv / cov qauv uas xav tau cov qauv kev ruaj ntseg thiab toughness, N normalized mob yog nyiam.
2, Cov khoom thiab kev lag luam twg yog ST52-3 feem ntau siv?
Teb: Kev tsim kho tshuab: Excavator, crane, loader structural Cheebtsam
