ASTM A709 Qib 50Wyog lub siab -lub zog qis- alloy weathering steel phaj tsim feem ntau rau kev siv choj thiab cov qauv siv uas ob qho tib si thauj khoom -cov kabmob muaj peev xwm thiab atmospheric corrosion kuj tseem ceeb.
Qhov tseem ceeb A709 Qib 50W weathering steel phaj muaj xws li qhov tsawg kawg nkaus lub zog ntawm 50 ksi (345 MPa), lub zog tensile yam tsawg kawg nkaus ntawm 70 ksi (485 MPa), thiab txhim kho atmospheric corrosion kuj.
ASTM A709 / A709M tshwj xeeb txheeb xyuas Qib 50W raws li qib huab cua thiab koom nrog A588 / A588M cov cai, thaum A709 specification ntxiv choj- cov kev cai tshwj xeeb thaum tsim nyog.
A709 Qib 50W Weathering Steel yog dab tsi?
A709 Qib 50W yog cov txheej txheem huab cua huab cua npog los ntawm ASTM A709 / A709M, ASTM specification rau cov qauv hlau siv hauv cov choj. ASTM cov ntaub ntawv teev npe Qib 50W [345W] ntawm cov qib huab cua thiab txuas nrog ASTM A588 / A588M.
Tsis zoo li cov qauv hlau uas ib txwm xav tau cov xim tiv thaiv nyob rau hauv qhov chaw raug, huab cua steel yog tsim los tsim cov txheej txheem tiv thaiv oxide nyob rau hauv qhov haum ntawm huab cua. Cov patina no tuaj yeem txo qhov kev loj hlob ntawm atmospheric corrosion thaum cov hlau raug tsim, nthuav tawm thiab khaws cia.
Txawm li cas los xij, huab cua steel tsis yog kev saib xyuas thoob ntiaj teb - dawb. Kev ntub dej tsis tu ncua, kev sib kis ntsev, kev raug dej hiav txwv, kev sib tsoo, cov dej tsis zoo thiab lwm yam kev ua phem tuaj yeem cuam tshuam rau nws tus cwj pwm corrosion. Yog li ntawd, ib puag ncig yuav tsum tau soj ntsuam ua ntej xaiv A709 Qib 50W weathering steel phaj.
A709 Qib 50W huab cua tsis kam Cov Khoom Siv Hluav Taws Xob Hlau
