Siab Zoo SM490 H Zoo Li Tus Hlau Beams

SM490 Hlau Li Cas?
SM490 H zoo li tus hlau nqaj lub zog yog lub zog loj qauv tsim qauv steel ua raws li Japanese muaj cov qauv (JIS G 3106). "SM" Sawv ntsug rau "Nruab Nrab-siab zog manganese steel" thiab muaj lub zog zoo thiab weldability rau ntau cov ntawv thov cov txheej txheem.

Cov tshuaj lom neeg muaj pes tsawg leeg ntawm SM490 Zoo Hlau Zoo Li Cov Hlau, Manganese, Silicon, Phosphorus, Cov Neeg Sulfur thiab cov khoom siv me me. Cov pa roj carbon cov ntsiab lus yog ua tib zoo tswj kom muaj kev sib npaug zoo ntawm lub zog thiab kev sib luag.
Carbon (c): {0. 18% Max
Manganese (MN): 1.60% Max
Silicon (si): {0. 55% Max
Phosphorus (p): 0. 035% Max
Sulphur (s): 0. 035% Max

Cov yam ntxwv ntawm SM490 h zoo li nqaj
High tensile lub zog: nrog tsawg kawg yog lub zog ntawm 490 MPa thiab qhov tsawg kawg tensile lub zog ntawm 590 MPa, nws yog qhov tsim nyog rau cov ntawv thov muaj zog.
Zoo weldability: nws tuaj yeem yooj yim welded siv cov qauv vuam cov qauv.
Ductility: nws tseem tswj hwm zoo thiab tuaj yeem tiv thaiv cov khoom xyaw yas tsis muaj kev tawg.
Corrosion Kuj: Nws muaj kev txhim kho corrosion tsis kam thiab yog qhov tsim nyog rau kev siv sab nraum zoov tom qab kev kho mob saum toj no.

Zoo Zoo SM490 H nqaj feem ntau siv nyob rau hauv: Lub tsev thiab choj tsim kho; cov txheej txheem thav ntawv ntawm cov chaw muaj tsheb; txhawb nqa cov qauv rau cov tshuab hnyav; Crane booms thiab lwm yam khoom nqa; nkoj nkoj thiab tawm cov qauv; Ntauwd thiab hluav taws xob kab qauv, thiab lwm yam.

Qhov zoo ntawm kev siv SM490 h-nqaj
Txhim kho cov txheej txheem kev ua tau zoo: Lub zog ua kom muaj zog rau-qhov hnyav piv rau kev sib tw rau lub sib zog, cov qauv siv tau ntau dua los ua.
Yooj yim rau Fab Kis: Yooj yim rau fabricate, txiav thiab weld, piv rau cov txheej txheem kev tsim kho.
Kev ntseeg tau: Muaj kev cia siab thiab kev nyab xeeb muaj kev vam meej hauv ntau cov ntawv thov.

Gnee steel tau tsim tsa nyob rau xyoo 2008, peb cov khoom tseem ceeb yog seem steel, lub tsev sib luag, thiab lwm yam. Peb zoo siab los muab koj tus nqi zoo tshaj plaws thiab cov lus qhia. Koj zoo siab tos txais koj mus ntsib peb lub tuam txhab.
