4. Yooj yim rau Fabricate: S355J2H steel tube yog ib qho yooj yim rau kev ua hauj lwm nrog, uas ua rau nws yooj yim rau fabricate rau hauv cov duab sib txawv thiab ntau thiab tsawg. Nws tuaj yeem welded, txiav, drilled, thiab machined yooj yim kom tau raws li cov kev xav tau ntawm kev siv sib txawv.

5. Lub teeb: S355J2H steel tube yog cov khoom siv hnyav, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas yuav tsum tau txo qhov hnyav. Nws kuj yog ib qho yooj yim los tuav thiab thauj, uas txo cov nqi tag nrho ntawm kev tsim khoom thiab kev teeb tsa.

S355J2H yog qib ntawm cov hlau uas tau siv dav hauv kev tsim kho kev lag luam vim nws lub zog thiab lub zog. Muaj ntau ntau yam ntawm lub cev uas ua rau S355J2H yog cov khoom tsim nyog rau cov qauv tsim.

Nov yog qee qhov tseem ceeb ntawm lub cev ntawm qib steel:

1. Siab tensile zog: S355J2H muaj lub zog ua haujlwm siab, uas txhais tau tias nws tuaj yeem tiv taus kev ntxhov siab ntau yam tsis muaj deforming lossis tawg. Qhov no ua rau nws yog ib qho khoom siv zoo tshaj plaws rau cov ntawv thov uas xav tau lub zog siab, xws li kev tsim cov choj, cov kav dej, thiab cov vaj tse siab.

2. Siab toughness: S355J2H muaj qhov toughness zoo heev, uas txhais tau tias nws tuaj yeem nqus tau lub zog yam tsis muaj kev tawg. Qhov no pab tiv thaiv kev tawg thiab lwm yam kev puas tsuaj thaum lub sij hawm tsim thiab siv.

3. Ductility: S355J2H yog cov ductile heev, uas txhais tau hais tias nws tuaj yeem yooj yim molded thiab zoo li tus rau hauv ntau yam ntaub ntawv yam tsis muaj cracking lossis tawg. Qhov no ua rau nws yog ib qho khoom siv zoo tshaj plaws rau vuam thiab lwm yam txheej txheem fabrication.

4. Corrosion kuj: S355J2H muaj kev tiv thaiv corrosion zoo heev, uas ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv hauv qhov chaw hnyav. Nws tuaj yeem tiv taus cov dej noo, tshuaj lom neeg, thiab lwm yam corrosive yam tsis muaj xeb lossis corroding.

5. Tsawg carbon cov ntsiab lus:S355J2H muaj cov ntsiab lus carbon tsawg, uas ua rau nws ib puag ncig-phooj ywg thiab rov ua dua tshiab. Qhov no txhais tau hais tias nws tuaj yeem siv tau rau hauv kev tsim kho kom ruaj khov, pab txhawb rau yav tom ntej ntsuab.
