EN 10025-2 S275J0 ZOV ZOG Txheej Txheem Steel Phaj

S275J0 yog hom qauv hlau qib hlau uas yog ib feem ntawm European cov txheej txheem ntawm cov hlau (EN 10025). Nws yog ib qho uas siv rau cov hom phiaj tsim dav dav thiab tshwj xeeb tshaj yog muaj nuj nqis rau nws cov nyiaj tshuav, ua rau muaj zog, thiab weldability.

Cov "s" hauv S275J0 qhia tias nws yog tus qauv steel hlau txheej txheem hlau, thiab "yog hais txog qhov tsawg kawg nkaus lub zog (hauv megapascals, mpa) ntawm cov khoom, uas yog 275 mpa.

Tus "J0" nyob rau hauv kev tsim qauv qhia tias tus qauv ntawm tus qauv hlau muaj qhov cuam tshuam tsawg kawg ntawm 27 txoj kev cuam tshuam ntawm 0℃hais tias nws yog resistant rau nkig bittle fracture ntawm qhov kub no.

S275J0 muaj cov tshuaj lom neeg muaj pes tsawg leeg muaj ob peb lub ntsiab tseem ceeb, uas muab nws lub zog thiab tawv:

Cov pa roj carbon (c):0.17% Max

Manganese (MN): 0.60-0.90%

Silicon (si):0.40% max

Phosphorus (p):0.035% max

Sulphur (s):0.035% max

Cov ntsiab lus sib xyaw ua ke muab cov khoom siv uas ruaj khov thiab haum rau ntau cov qauv kev tsim qauv thiab cov ntaub ntawv engineering.

Cov khoom siv neeg kho tshuab ntawm S275J0 yog lwm qhov laj thawj nws tau xaiv ntau rau kev tsim txoj haujlwm. Ntawm no yog cov khoom tseem ceeb ntawm cov hlau no:

Paib lub zog:275 MPa (yam tsawg kawg nkaus)

Lub zog tensile:430-580 MPA

Elongation:Kwv yees li 22% (hauv 8 zaug lub cheeb ntawm cov hnoos qeev)

Kev Cuam Tshuam:27 j ntawm 0 degree

Modulus ntawm elasticity:210 GPA

Cov khoom siv no kom ntseeg tau tias S275J0 ua tau zoo nyob rau hauv kev ntxhov siab, muab qhov txaus ua kom kub, thiab muab qhov tsim nyog hloov rau cov hom phiaj tsim kho.

S275J0 hlau yog ntau yam thiab yog siv nyob rau hauv ntau cov qauv thiab kev lag luam. Qee qhov kev siv feem ntau suav nrog:

Txheej txheem steelwork

S275J0 yog nquag siv nyob rau hauv kev tsim kho ntawm cov tsev, choj, thiab lwm yam phiaj xwm lwm txoj haujlwm. Nws cov txiaj ntsig lub zog thiab kev cuam tshuam tsis kam ua rau nws zoo tagnrho rau cov ntawv thov uas cov steel yuav tsum tau nqa cov khoom lag luam thiab tiv thaiv sab nraud.

Hlau Beams thiab Txhua

S275J0 feem ntau yog siv nyob rau hauv kev tsim cov hlau nplaum thiab kab ntawv rau kev tsim kho cov qauv loj. Vim nws zoo heev weldability, nws yog ib qho yooj yim rau ntaub ua rau ntau daim duab thiab ntau thiab tsawg kom tau raws li cov qauv tsim tshwj xeeb.

Kev tsim kho ntawm cov tshuab sib xws

S275J0 cov haujlwm ua haujlwm zoo thiab sib npaug ntawm lub zog thiab ductility ua nws haum rau kev tsim cov tshuab sib, qhov twg ob qho kev nruj thiab yoog raws yog qhov tseem ceeb.

Kev Lag Luam Thauj

S275J0 yog siv nyob rau hauv ntau lawm ntawm ntau yam khoom siv rau kev thauj khoom, suav nrog kev tsheb nqaj hlau, cov tsheb thauj khoom, thiab shocks. Nws muaj kev sib xyaw ua ke ntawm lub zog thiab kev cuam tshuam tsis zoo yog qhov zoo tagnrho rau cov khoom siv uas yuav tsum ua kom dhau tas li hnav thiab kua muag.

Cov hlau txheem hlau rau sab nrauv thiab cov qauv tsim

Cov hlau S275J0 tseem siv rau hauv cov roj pov thiab roj platform, nrog rau kev ua haujlwm rau corrosion thiab cuam tshuam ntawm tsawg kub yog qhov tseem ceeb.
