S355J2 S355J2N H zoo li cov hlau

S355J2 yog European tus qauv kub- dov structural steel khoom, S355J2+N yog ib hom EN10025 European txheem steel phaj, piv nrog lub teb chaws tus qauv GB / T1591-2007, GB / T3274-2008 Q345D, nws tus me nyuam raws li txoj cai - J220℃yuav tsum muaj kev cuam tshuam tsis zoo, qhov cuam tshuam rau kev sim 2. Raws li rau tom kawg + N txhais tau hais tias nws yog sib npaug rau normalizing dov es nws yuav tsum normalized, uas tsuas yog ib txoj kev ntawm naming lub steel tooj nyob rau hauv tus qauv.

Ib tug xov tooj ntawm European - cov qauv tau hais tseg tau txiav txim siab ntawm kev faib tawm, raws li qhov muaj pes tsawg leeg, ntawm ntau hom hlau. Cov no tau muab faib ua ob pawg loj. Thawj suav nrog cov hlau yooj yim thiab zoo, feem ntau, siv thiab pheej yig dua, thaum thib ob suav nrog cov hlau tshwj xeeb.

Cov hlau ntawm thawj pab pawg tseem hu ua steel siv, muaj cov yam ntxwv qis dua li cov hlau tshwj xeeb tab sis tseem tsim nyog rau kev tiv thaiv kev ntxhov siab zoo li qub. Lawv yog siv thaum lawv tseem nyob rau hauv lub raw dov lub xeev thiab lawv ua thiab installation yuav siv sij hawm qhov chaw los ntawm vuam. Cov feem pua ​​​​ntawm cov pa roj carbon monoxide nyob rau hauv cov alloys no yuav tsum tsis pub tshaj 0.41%.

Cov hom hlau hauv nqe lus nug, S355JR thiab J2+N, ob qho tib si poob rau hauv thawj pab pawg thiab tshwj xeeb tshaj yog rau hauv qeb ntawm yog li- hu ua cov qauv hlau. Hauv lwm lo lus nws yog siv los ua cov khoom siv rau kev tsim kho pej xeem ntawm cov qauv hlau ua cov khoom thauj -cov kabmob lossis hauv cov haujlwm ua los ntawm cov pob zeb uas muaj zog.

Qhov tshwj xeeb ntawm kev siv qhov tseem ceeb yog nyob ntawm nws cov yam ntxwv, ntawm qhov fragility thiab ductility thiab nyob rau ntawm durability thiab mechanical resistance ntawm cov khoom.

Teb chaws Europe tau txiav txim siab tias ib qho acronym txhais cov txheej txheem peculiarities ntawm cov qauv hlau, nrog rau thawj tus cim qhia nws siv. Hauv qhov no, tsab ntawv S qhia tias cov hlau yog siv rau cov kws ntoo hlau.

Qhov thib ob ntawm cov lus luv luv, tus naj npawb 355, qhia qhov tsawg kawg nkaus qhov kev ntxhov siab, qhov kawg muab cov hlau ib lub tswv yim ntawm nws cov ductility, txhais tau tias muaj peev xwm tiv taus deformation. Thaum qhov kev txwv no dhau lawm, cov hlau hla dhau los ntawm tus cwj pwm hloov pauv hloov tau, uas yog, nws rov qab mus rau nws qhov qub, mus rau ib lub yas uas nthuav tawm cov deformations tsis tuaj yeem thiab cov khoom siv tau txais qhov xwm txheej ntawm cov txiaj ntsig, txawm tias qhov ua rau muaj kev ntxhov siab tsis ua haujlwm. Qhov no yog ib qho tseem ceeb heev vim hais tias nws qhia tau hais tias qib ntawm tsis kam mus rau ib tug kev nyuaj siab uas cov qauv los yog cov khoom ua nrog rau tej yam steel muaj peev xwm nyiaj tau. Tsis tas li ntawd xwb, nws tseem ceeb heev seb cov hlau yuav tom qab ntawd raug rau kev ua haujlwm ntxiv xws li dov lossis forging.

Peb tau cog lus rau kev tswj kom zoo thiab kev pabcuam rau cov neeg siv khoom. Peb cov neeg ua haujlwm yeej ib txwm npaj los tham txog koj cov kev xav tau thiab ua kom tiav cov neeg siv khoom txaus siab. Peb tsiv los ntawm Tuam Tshoj mus rau lub ntiaj teb no thiab ua tau raws li cov kev xav tau ntawm peb cov neeg muas zaub. Peb cov neeg muas zaub yog thoob plaws Tebchaws Europe, Türkiye, Indonesia, thiab lwm yam, thiab txaus siab rau lub koob npe nrov ntawm peb cov neeg siv khoom. Peb kuj zoo siab tos txais koj tuaj xyuas peb lub tuam txhab thiab vam tias peb tuaj yeem txhim kho ua ke thiab tsim lub neej yav tom ntej zoo dua.

Yog tias koj muaj lus nug lossis lwm yam kev xav tau ntawm cov hlau, thov hu rau peb thiab peb ib txwm nyob ntawm koj qhov kev pabcuam!
