ASTM A588 Corrosion Resistant PhajYog lub siab - lub zog, qis {{}} almoy qauv steel zoo li cov ces kaum, cov phiaj, cov phiaj hlau, thiab cov hlau. Nws muaj kev txhim kho atmospheric corrosionance, ua rau nws haum rau kev siv qhov hnyav, thiab txuas ntxiv rau lub neej yog qhov tseem ceeb.
ASTM A606-4 Corrosion Resistant PhajYog lub siab - lub zog, qis {-} alloy alloy rolled steel ntawv, sawb, thiab coil. Nws yog npaj rau cov txheej txheem thiab lwm cov laj thawj uas cov kev txuag hluav taws thiab ua kom muaj zog durability yog qhov tseem ceeb.
Cov Nta Tseem Ceeb
A588 muab cov atmospheric tsis zoo piv rau cov hlau hlau xws li A36 thiab A572-50, nrog lossis tsis muaj tooj liab ntxiv. Qhov no ua rau nws haum rau ntau cov ntawv thov txawm nyob hauv tej yam kev mob uas tsis pom zoo.
ASTM A588 muaj tsawg kawg yog los lub zog ntawm 50 ksi (kilo- phaus ib sab square) thiab qhov tsawg kawg tensile lub zog ntawm 70 ksi. Lub zog siab no ua kom muaj kev ntseeg siab thiab thauj khoom {{{bearing muaj peev xwm nyob rau hauv ntau qhov chaw.
A606-4 Muaj cov kev ua yeeb yam zoo dua corroshologor tsis kam muab piv rau cov hlau hlau, nrog lossis tsis muaj tooj liab ntxiv. Qhov no ua rau nws haum rau ntau cov ntawv thov uas tsis tau pleev xim.
A606-4 muaj cov ntsiab lus ntxiv uas pab rau nws cov khoom siv txhim kho corrosion tsis kam thiab cov khoom siv tshuab.
ASTM A606 {{{- 4 muaj tsawg kawg yog lub zog ntawm 50 ksi phaus ib sensile lub zog ntawm 70 ksi. Lub zog siab no ua kom muaj kev ncaj ncees thiab cov kabmob thauj khoom muaj peev xwm ua ntau qhov chaw.
