SA516Gr70 Boiler phaj hlau
SA516Gr70 belongs rau American standard thawv steel phaj thiab dav siv nyob rau hauv kev tsim cov hlab ntsha siab nyob rau hauv roj av, tshuaj kev lag luam, fais fab mov, boilers thiab lwm yam teb. Nws muaj cov cuab yeej zoo heev thiab kev ua haujlwm vuam zoo.
SA516Gr70 American standard thawv steel phaj yog ib tug tsawg-alloy high-strength steel phaj uas muaj tshuaj lom neeg muaj pes tsawg leeg thiab txhua yam khoom raws li cov kev cai ntawm American standard ASTM A516 / A516M.
SA516Gr70 siab lub nkoj phaj muaj cov yam ntxwv hauv qab no:
1. Lub zog siab: SA516Gr70 steel boiler phaj muaj lub zog muaj zog thiab tensile lub zog, thiab tuaj yeem tiv taus siab loj thiab khoov kev ntxhov siab, ua kom muaj kev ruaj ntseg thiab ruaj khov ntawm lub thawv.
2. Tsis tshua muaj kub toughness: SA516Gr70 boiler steel phaj qhia tau hais tias zoo toughness nyob rau hauv qis kub thiab muaj peev xwm tiv taus tsis tshua muaj kub brittle puas, kev txhim kho kev ruaj ntseg ntawm lub thawv.
3. Kev ua haujlwm vuam zoo: SA516Gr70 siab lub nkoj steel muaj qhov zoo weldability thiab tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm ntau yam txheej txheem vuam, ua kom cov vuam zoo thiab kev ntseeg siab ntawm lub nkoj.
4. Zoo corrosion kuj: SA516Gr70 boiler phaj tau txais kev kho tshwj xeeb los tiv thaiv corrosion thiab muaj kev tiv thaiv corrosion zoo thiab tuaj yeem hloov kho raws li qhov yuav tsum tau muaj ntawm ntau qhov chaw corrosive.
SA516Gr70 nkoj phaj muaj cov khoom siv zoo heev thiab cov khoom siv vuam, yog li nws tau siv dav hauv kev tsim cov hlab ntsha hauv cov roj av, tshuaj lom neeg kev lag luam, chaw nres tsheb fais fab, boilers thiab lwm yam.
