KHOOM

Tianjin BRISK STEEL tsom rau cov khoom tsim thiab muab cov seem hollow thiab cov yeeb nkab steel

Ua raws liBS EN 10210, tau tshaj ASTM A501, AS 1163, JIS G3466, thiab GB / T 6728rau cross-application scenarios; nws mechanical zog yog piv rauS355J2 steel phaj tau teev nyob rau hauv EN 10025-2txheem.

Peb muab ntau qhov loj me kom tau raws li qhov yuav tsum tau ua ntawm ntau qhov project, nrog rau kev tswj qhov ntev kom txo tau cov nqi ua tom ntej:

• Seem Tshooj:Circular (CHS), Square (SHS), Rectangular (RHS) - txhua yam muaj raws li cov qauv kev xaiv

• Sab nraud txoj kab uas hla (OD):Lub voj voog 16.3mm ~ 3048mm; Square tubes 20x20mm ~ 1000x1000mm; Rectangular raj 50x30mm ~ 1200x1000mm

• Phab ntsa Thickness (WT)3.2mm ~ 50mm (customizable mus txog 50mm rau kev txiav txim tshwj xeeb)

• Ntev:6m ~ 12m (tus qauv), 3m ~ 18m (customizable); Kev kam rau siab: Ntev ± 500mm (kwv yees) lossis 0 / +10mm ~ 0 / +15mm (qhov ntev)

• Dimensional kam rau uaSab nraud txoj kab uas hla ± 1% (yam tsawg ± 0.5mm, siab tshaj ± 10mm); Phab ntsa thickness -10%; Qhov hnyav ± 6% rau tus kheej ntev

S355J2H steel tubesua kom pom kev ua haujlwm zoo heev, tshwj xeeb tshaj yog qis dua -kub toughness, haum rau hnyav-load thiab qis- daim ntaub ntawv kub:

• Yield zog (Reh): Minimum 355 N/mm² (for thickness ≤16mm); 345 N/mm² (for thickness >16mm); maj mam txo nrog nce thickness, piv txwv li, 335 N / mm² rau 16-40mm, 325 N / mm² rau 40-63mm [3].

• Tensile zog (Rm):470 ~ 630 N / mm², uas yog piv rau S355 series structural steels nrog lub zog tensile ntau ntawm 450-680 N / mm² [3].

• Elongation (A):Tsawg kawg 22%

• Impact zog:27J @ -20 degree, ua tau raws li qhov yuav tsum tau muaj qhov kub thiab txias ntawm J2 qib zoo, ua kom muaj zog zoo hauv cov cheeb tsam txias thiab ib puag ncig hnyav[3].

• Carbon Equivalent (CEV): Ntau tshaj 0.45%, kom ntseeg tau zoo heev weldability; preheating tej zaum yuav tsum tau tsuas yog rau tuab - cov hlab ntsa (＞ 20mm) los yog complex welding qauv.

Kev tswj cov tshuaj muaj pes tsawg leeg nruj me ntsis kom ntseeg tau tias cov khoom ruaj khov thiab kev ua tau zoo (max qhov tseem ceeb tshwj tsis yog tau teev tseg), ua raws li covCov kev cai tshuaj ntawm S355J2 series structural steels:

• Cov pa roj carbon (C): 0.22%

   

• Silicon (Si): 0.55%

   

• Manganese (Mn): 1.60%

   

• Phosphorus (P): 0.025%

   

• Sulfur (S): 0.025%

   

• Niobium (Nb), Vanadium (V), Titanium (Ti): Cov lej (ib tus qauv EN 10210) txhawm rau txhim kho cov nplej kom zoo thiab cov khoom siv kho tshuab

   

• Aluminium (Al): Cov ntsiab lus tsawg kawg nkaus (rau nplua- tswj cov nplej); Copper (Cu): Tsawg dua lossis sib npaug li 0.55% (cov kab ke los pab tiv thaiv corrosion)

• High Strength & Lightweight:Nrog rau qhov tsawg kawg nkaus tawm lub zog ntawm 355 N / mm², nws ua rau cov khoom siv txuag nqi thiab cov qauv sib zog thaum tuav cov qauv kev ncaj ncees, txo qhov hnyav tag nrho thiab kev tsim kho; nws lub zog yog me ntsis siab dua li cov pa roj carbon zoo tib yam steel, haum rau nruab nrab -load bearing scenarios[4].

• Kev ua tau zoo heev:Tag nrho cov hlau tua ua kom zoo weldability, formability, thiab machinability; nruj kaum radii (<2t) exceed standard requirements, enhancing aesthetic appeal and avoiding brittle fracture risks associated with cold-formed products; welding can adopt conventional processes, and no preheating is required for thin-walled tubes.

• Superior Low-Tsub Toughness:Ua raws li qib J2 zoo, nrog rau kev cuam tshuam lub zog ntawm 27J @ -20 degree, ua rau nws siv tau rau hauv cov cheeb tsam txias (xws li cov teb chaws Europe sab qaum teb, sab qaum teb Asia) thiab qis- qhov chaw ua haujlwm kub, tsis txhob tawg tawg nyob rau hauv qhov kub thiab txias [3].

• Precise Dimensional Accuracy:Advanced kub-tiav tshuab ua kom zoo ib yam ntawm qhov chaw tiav thiab nruj me ntsis kam rau ua, txo qhov xav tau rau kev ua haujlwm thib ob thiab txhim kho kev tsim kho.

• Versatile Corrosion Protection:Kev xaiv saum npoo kev kho mob suav nrog cov oxide dub, roj txheej, galvanizing, 3LPE, 3LPP, thiab FBE, zoo txhim kho corrosion kuj; Cov ntsiab lus tooj liab nyob rau hauv cov khoom kuj pab txhim kho atmospheric corrosion tsis kam mus rau ib qho twg, ncua kev pab cuam lub neej nyob rau hauv av, marine, los yog industrial cheeb tsam.

• Certified Quality:Tag nrho cov khoom yog CE cim, batch{0}} kuaj, thiab muab nrog 3.1 xeem daim ntawv pov thawj rau tag nrho cov batch traceability, ua raws li thoob ntiaj teb cov qauv thiab mechanical daim ntawv thov, thiab ua tau raws li tus qauv tswj zoo ntawm EN 10210 thiab EN 10025 series qauv.

EN 10210 S355J2H steel hlab yog dav siv nyob rau hauv ntau yam siab -xav tau tej yaam num vim lawv cov kev sib npaug, tshwj xeeb tshaj yog haum rau qis- kub thiab nruab nrab- load scenarios, suav nrog tab sis tsis txwv rau:

• Kev Tsim Kho & Infrastructure:Lub hauv paus tsim, kab, kab, trusses rau vaj tse, coj mus muag, thiab industrial vaj tse; choj girders, kev txhawb nqa, thiab overpass / underpass lug; railway chaw nres tsheb moj khaum thiab tshav dav hlau chaw (cov neeg caij tsheb terminals, aircraft hangars); tshwj xeeb tshaj yog tsim rau kev tsim kho tej yaam num nyob rau hauv cheeb tsam txias.

• Mechanical Engineering:Cov qauv kev txhawb nqa rau cranes, excavators, thiab lwm yam tshuab hnyav; lub moj khaum rau kev lag luam khoom, cia racks, thiab conveyor systems; mechanical structural parts bearing static or dynamic loads, qhov twg tsawg -kub toughness yuav tsum tau.

• Offshore & Marine:Cov yam ntxwv ntawm cov khoom siv rau offshore roj thiab roj platforms; nkoj superstructures, masts, thiab kev txhawb nqa systems, nrog rau kev tiv thaiv corrosion rau hnyav marine ib puag ncig; haum rau kev ua haujlwm offshore hauv qis -tej dej hiav txwv kub.

• Renewable Zog:Lub hauv paus thiab cov qauv yees rau cua turbines; kev txhawb nqa cov qauv rau lub hnub ci vaj huam sib luag, tshwj xeeb tshaj yog muaj feem xyuam rau cov phiaj xwm cua fais fab hauv cheeb tsam txias thiab alpine.

• Lwm yam kev siv:Cia tso tsheb hlau luam thiab cov khoom siv silo; pipeline kev txhawb nqa nyob rau hauv industrial chaw; warehouse racks; thiab cov txheej txheem nyob rau hauv mining, tshuaj, thiab kev thauj mus los industries, qhov twg txhim khu kev qha toughness thiab lub zog yuav tsum tau.
