Muaj zog h hlau nqaj A992

Tsim los rau cov txheej txheem txheej txheem, A992 hlau HAR muaj lub zog zoo, weldabiliveness, ua rau nws zoo tagnrho rau cov tsev, cov choj thiab cov tshuab hnyav.

Tshuaj lom neeg muaj pes tsawg leeg ntawm A992 H Nqaj Tsim

Cov pa roj carbon (c): tsawg dua lossis sib npaug rau 0. 20%
Manganese (MN): Tsawg dua lossis sib npaug nrog 1.60%
Silicon (Si): tsawg dua los yog sib npaug rau 0. 55%
Phosphorus (p): tsawg dua lossis sib npaug rau 0. 035%
Sulphur (s): Tsawg dua lossis sib npaug rau 0. 035%
Microalloy (NB, v): kab kawm siv los txhim kho lub zog thiab tawv.

Cov cuab yeej kho tshuab ntawm A992 H seem Beam
Paib lub zog (σS): ntau dua los yog sib npaug rau 345 MPa (50 ksi)

Tensile lub zog (σB): ntau dua lossis sib npaug nrog 450-630 MPa (65-91 ksi)

Elongation (Δ): ntau dua lossis sib npaug rau 20%

Kev Cuam Tshuam Cov tawv: Zoo tshaj plaws ntawm chav sov; Haum rau kev ua kom muaj zog.

Cov ntawv thov ntawm A992 qauv ha nqaj

Tsev qauv qauv: kab ntawv, kab teeb thiab thav ntawv nyob rau hauv cov tsev siab thiab muaj chaw muaj kev lag luam.
Txuas hniav: Cov khoom siv thauj khoom uas yuav tsum muaj kev qaug zog tsis kam.
Cov nkoj thiab cov tshuab hnyav: Offshore platforms, nkoj nkoj thiab crane tshuab.

Kev Tsim Txheej Txheem Ntawm A992 H Tshooj Hlau Beob

Kub Rolling: Tus Hlau Billet yog rhuab rau qhov kub thiab txias thiab hla dhau ntawm cov millet mills los thov nias siab rau lub fillet, shaping nws mus rau hauv tus yam ntxwv H-zoo li tus cwj pwm. Cov txheej txheem no tsis tsuas yog tsim cov duab yam xav tau, tab sis kuj tseem ua kom cov qauv sib dhos ntawm cov hlau, txhim kho nws cov khoom siv neeg kho mob.
Cua txias thiab ncaj: tom qab kub dov, lub H-nqaj tso cai rau kom txias mus rau chav sov. Qhov txheej txheem tsim txias no pab tau txuas ntxiv tsim kho microstructure thiab cov khoom siv kho tshuab ntawm cov hlau. Tom qab txias, lub H-nqaj yuav ua kom ncaj qha los ua kom ntseeg tau qhov tseeb thiab kev ncaj.

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.
