huab cua resistant steel Khoom Description
STM A709-50W yog cov qauv kev qhia tshwj xeeb rau cov qauv hlau siv feem ntau hauv kev tsim cov choj steel. Lub atmospheric corrosion kuj ntawm cov hlau no nyob rau hauv feem ntau ib puag ncig yog considerably zoo dua li cov carbon steel nrog los yog tsis muaj tooj liab.ASTM A709-50W yuav tsum muaj ib tug atmospheric corrosion Performance index ntawm 6.00 los yog zoo dua.
A709-50W nyob rau hauv nws lub xeev raug (tsis pleev xim) yog tsim rau ntau daim ntawv thov xws li: cov neeg taug kev txuas hniav, txoj kev loj choj thiab lwm yam khoom siv choj, kev tsheb ciav hlau txuas hniav thiab hla hla.
ASTM A709-50W muaj qhov tsawg kawg nkaus lub zog ntawm 50ksi thiab lub zog tensile yam tsawg kawg nkaus ntawm 70ksi.
