S275jr S355j2 Sab saum toj Muag Khoom Lub Tsev Steel Lub kaum sab xis hlau hauv Tshuag

Peb S275jr thiab S355j2 steel lub kaum sab xis steel, sab saum toj - muag cov khoom kab uas tsim los rau cov qauv siv hauv tsev, tau npaj txhij muaj nyob rau hauv Tshuag kom tau raws li qhov xav tau sai. Raws li ib qho tseem ceeb ntawm cov qauv, lub kaum sab xis steel nta ib txoj cai meej - lub kaum sab xis -sectional tsim, kom ntseeg tau tias muaj kev cuam tshuam kev ntxhov siab, kev thauj khoom zoo heev - cov kabmob muaj peev xwm, thiab kev sib kis tau zoo. Tsim nyob rau hauv nruj raws li European EN cov qauv, nws integrates superior mechanical zog, zoo heev weldability, thiab robust durability, ua rau nws ib tug nyiam xaiv rau ntau yam ntawm lub tsev tsim tej yaam num thiab tau txais nws siab nyob rau hauv kev ua lag luam.

S275jr thiab S355j2 yog siab- zoo European qauv carbon structural steel qib, muaj koob npe nrov rau lawv cov kev ua tau zoo tshaj plaws hauv kev tsim qauv siv. S275jr, siv dav hauv nruab nrab- qib zog, khav theeb qhov muaj zog tsawg kawg nkaus ntawm 275 MPa (rau thickness Tsawg dua lossis sib npaug li 16 hli) thiab zoo ductility. Lub ntsiab lus "jr" qhia txog nws qhov yuav tsum tau ua kom muaj zog toughness (kuaj ntawm chav tsev kub), kom ntseeg tau tias kev ua tau zoo nyob rau hauv ib puag ncig hauv tsev. Nws yog qhov zoo tagnrho rau kev tsim cov khoom siv xws li lub ru tsev trusses, phab ntsa thav duab, thiab bracings hauv vaj tse, kev lag luam, thiab cov tsev lag luam. S355j2, qib siab - lub zog muaj zog nrog kev ua tau zoo dua qub, muaj qhov tsawg kawg nkaus tawm lub zog ntawm 355 MPa (rau thickness Tsawg dua lossis sib npaug li 16 hli). Cov lus "j2" qhia txog nws qhov kev cuam tshuam zoo tshaj plaws (kuaj ntawm -20 degree), ua rau nws tsim nyog rau qis- qhov kub thiab txias- lub luag haujlwm lub tsev xws li loj - txuas txuas, lub tsev siab siab, thiab kev txhawb nqa cog. Ob qib qhia tshwj xeeb weldability thiab machinability, ua kom yooj yim fabrication thiab sib dhos kom phim ntau hom kev tsim qauv.

Cov txheej txheem tsim khoom ntawm peb S275jr thiab S355j2 lub tsev qauv steel lub kaum ntse ntse ua raws li European EN cov qauv, lav cov khoom zoo thiab sib xws. Raw steel billets raug nruj ua ntej- tshuaj xyuas, suav nrog cov ncauj lus kom ntxaws txog tshuaj lom neeg thiab kev tshuaj xyuas cov khoom siv tshuab, kom ntseeg tau tias lawv ua tau raws li qhov xav tau ntawm qib S275jr thiab S355j2. Cov tub ntxhais tsim tau txais cov txheej txheem kub siab tshaj - dov tshuab: billets yog rhuab mus rau qhov kub thiab txias (siab tshaj 1050 degree) kom ua tau zoo plasticity, ces yog dov los ntawm ib tug series ntawm cov kws tshaj lij mills los ua tus qauv kaum steel profile. Qhov kub no - dov txheej txheem refines lub steel lub grain qauv, ho txhim khu nws toughness, tensile lub zog, thiab structural stability thaum lub sij hawm kom paub meej meej qhov tseeb (ntev ntev, thickness, txoj cai kaum sib txawv) thiab ib tug du nto tiav. Tsis tas li ntawd, xaiv cov kev kho mob saum npoo av xws li galvanization, epoxy txheej, los yog kev pleev xim los tiv thaiv - xeb kuj muaj los txhim kho corrosion, ncua cov khoom siv lub neej nyob rau sab nraum zoov, ntub dej, lossis hnyav hauv tsev.

Raws li cov khoom lag luam saum toj kawg nkaus - muag khoom rau kev tsim vaj tsev, S275jr thiab S355j2 steel lub kaum sab xis yog siv dav hauv ntau yam kev tsim kho. S275jr yog dav siv nyob rau hauv kev tsim vaj tsev, nrog rau cov tsev nyob, cov tsev ua haujlwm, cov khw muag khoom, thiab cov chaw ua haujlwm, ua haujlwm ua cov tswv cuab, kev sib tsoo, kev txhawb nqa hauv pem teb, thiab cov pob zeb ua vaj tse. S355j2, nrog nws lub zog siab thiab zoo heev qis- qhov kub thiab txias, yog qhov tsim nyog rau cov haujlwm xav tau ntau dua xws li cov tsev siab - nce siab, loj- cov chaw ntau pob, cov qauv choj, cov kav xa hluav taws xob, thiab cov khoom siv sab nrauv. Qhov muaj nyob hauv - cov khoom lag luam hauv Tshuag ua rau kev xa khoom sai, ua kom lub sijhawm ua haujlwm luv luv thiab ua tau raws li qhov xav tau ceev ntawm cov sijhawm tsim kho. Ob qib ntxiv rau ib leeg, tso cai rau cov neeg siv khoom xaiv tau yooj yim raws li qhov yuav tsum tau ua ntawm qhov project load, ib puag ncig, thiab cov phiaj xwm peev nyiaj, kom ntseeg tau qhov kev ua tau zoo ntawm cov qauv thiab cov nqi- ua tau zoo.

Peb tau cog lus los muab siab -zoo S275jr thiab S355j2 lub tsev qauv steel lub kaum sab xis steel, nrog rau kev tswj hwm kev ua tau zoo thoob plaws hauv kev tsim khoom thiab cov khoom siv. Txhua batch ntawm cov khoom tiav tau raug kuaj nruj, suav nrog tshuaj lom neeg tshuaj ntsuam xyuas (ua raws li EN 10025 tus qauv), kev ntsuas cov cuab yeej cuab tam (yield zog, tensile zog, elongation, cuam tshuam toughness), qhov tseeb qhov tseeb, thiab tshuaj xyuas qhov zoo. Peb cov khoom hauv-cov khoom lag luam suav nrog ntau yam ntawm qhov loj me, nrog cov ceg ntev ntawm 20mm txog 200mm, thicknesses los ntawm 3mm mus rau 24mm, thiab ntev customizable, tag nrho ua tau raws li cov kev xav tau ntawm ntau lub tsev ua haujlwm. Nrog cov khoom lag luam txhim khu kev qha, cov khoom lag luam txaus, thiab cov kws tshaj lij tom qab- kev muag khoom, peb muab cov neeg siv khoom zoo thiab tus nqi- cov qauv kev daws teeb meem zoo rau lawv cov kev xav tau kev tsim vaj tsev, ua kom peb txoj haujlwm ua tus neeg muag khoom ntseeg siab ntawm sab saum toj - muag lub tsev qauv steel kaum steel.
