Nyob rau tib lub sijhawm, peb cov hlau phaj kuj tau cog lus tias yuav dhau los ua cov txheej txheem kev tswj xyuas zoo thiab kev tshuaj xyuas kom ntseeg tau tias lawv qhov zoo, kev ua tau zoo thiab kev ntseeg tau.
Nyob rau hauv luv luv, A516Gr70 siab hlab ntsha steel phaj yog ib tug high-zoo, multi-functional, dav siv steel phaj cov ntaub ntawv, uas tau dav siv nyob rau hauv ntau yam siab hlab ntsha thiab boilers thiab lwm yam sij hawm. Txawm hais tias koj nyob hauv kev lag luam, aviation, lossis tsheb, peb muaj kev ntseeg siab hauv kev muab cov khoom zoo tshaj plaws thiab cov kev pabcuam.
Cov yam ntxwv tseem ceeb ntawm A516Gr70 steel phaj
1. Lub zog siab thiab tawv: A516Gr70 steel phaj muaj cov khoom siv zoo heev, thiab nws lub zog tensile feem ntau yog nyob nruab nrab ntawm 500-600MPa, uas tuaj yeem ua tau raws li qhov xav tau ntawm ntau yam haujlwm nyuaj. Nyob rau tib lub sijhawm, cov phaj steel kuj muaj qhov zoo heev toughness, uas tuaj yeem tswj tau qhov kev ua tau zoo nyob rau hauv kev cuam tshuam kev thauj khoom, txo qhov kev pheej hmoo ntawm kev puas tsuaj rau cov khoom siv hauv kev sib tsoo tsis tau npaj txhij.
2. Kev ua haujlwm vuam zoo: A516Gr70 steel phaj muaj qhov zoo tshaj plaws vuam kev ua tau zoo, uas tuaj yeem tswj kev ua haujlwm ruaj khov hauv cov txheej txheem vuam, txo cov khoom siv vuam tsis zoo, thiab txhim kho cov pob qij txha zoo. Qhov no feature ua rau cov hlau phaj muaj ib tug dav daim ntawv thov kev cia siab nyob rau hauv lub tshav pob ntawm siab hlab ntsha manufacturing.
3. Kev tiv thaiv corrosion zoo heev: A516Gr70 steel phaj muaj cov qauv nruj nruj thiab cov tshuaj lom neeg muaj pes tsawg leeg, ua rau cov phaj hlau muaj kev tiv thaiv corrosion zoo dua thiab ua haujlwm ntev. Cov phaj hlau no tuaj yeem ua haujlwm ruaj khov nyob rau hauv acidic lossis alkaline ib puag ncig rau lub sijhawm ntev thiab txuas ntxiv lub neej kev pabcuam ntawm cov khoom siv.
Tshuaj muaj pes tsawg leeg ntawm A516Gr70 steel phaj
Cov tshuaj lom neeg tseem ceeb ntawm A516Gr70 steel phaj suav nrog carbon (C Tsawg dua lossis sib npaug rau 0.30%), silicon (Si: {{10}} }. %) thiab lwm yam. Cov kev faib ua feem ntawm cov ntsiab lus no tau raug tswj kom ua tau raws li qhov yuav tsum tau siv hauv ntau qhov chaw ua haujlwm.
A516Gr70 steel phaj daim ntawv thov teb
A516Gr70 steel phaj yog dav siv nyob rau hauv petrochemical, lub zog, kev tsim kho thiab lwm yam kev lag luam ntawm cov hlab ntsha siab, cia tso tsheb hlau luam thiab cov kav dej thiab lwm yam khoom siv. Hauv cov khoom siv no, A516Gr70 steel phaj tsuas yog ua lub luag haujlwm ntawm kev tiv thaiv siab, tiv thaiv corrosion thiab to, uas yog qhov tseem ceeb rau kev ua haujlwm ruaj khov ntawm cov khoom siv mus ntev.
Petrochemical teb: A516Gr70 steel phaj yog dav siv nyob rau hauv kev tsim cov tso tsheb hlau luam thiab cov kav dej rau kev thauj cov roj av thiab tshuaj raw khoom thiab lwm yam xov xwm.
Fais fab teb: A516Gr70 steel phaj yog siv rau hauv kev tsim cov boilers thiab siab hlab ntsha thiab lwm yam khoom siv, rau tiam ntawm chav thiab kub thiab siab gases.
Kev tsim kho: A516Gr70 steel daim hlau kuj tseem siv rau hauv cov pob zeb ua kom muaj zog los txhim kho cov kabmob muaj peev xwm thiab kav ntev ntawm lub tsev.
