Dab tsi yog ASTM A588 Corten steel phaj?
ASTM A588 steel phajyog lub siab -lub zog qis- alloy (HSLA) weathering structural steel qib tshwj xeeb uas tsim los rau ntev -lub sij hawm atmospheric corrosion kuj nyob rau hauv ib puag ncig sab nraum zoov. Nws yog dav siv nyob rau hauv choj kev tsim kho, lub tsev facades, structural steel tej yaam num, tsheb lug, thiab toj roob hauv pes sculptures.
Cov hlau no yog tsim los ntawm kev ntxiv tooj liab (Cu), chromium (Cr), thiab npib tsib xee (Ni) rau cov pa qis - alloy steel. Cov tshuaj lom neeg muaj pes tsawg leeg yog kwv yees li: tooj liab (Cu) 0.20–0.40%, chromium (Cr) 0.40–0.65%, thiab npib tsib xee (Ni) 0.25–0.50% (tus nqi yuav txawv me ntsis nyob ntawm qhov tshwj xeeb thiab ntsuas kub). Cov alloying ntsiab no ho txhim kho nws cov tsis kam rau atmospheric corrosion.
Nyob rau hauv tej yam ntuj tso raug, ASTM A588 steel feem ntau pib tsim ib tug thawj oxide txheej nyob rau hauv 3-6 lub hlis, thiab ib tug ruaj khov, ntom tiv thaiv patina maj mam tsim nyob rau hauv 1-3 xyoo. Qhov no patina zoo thaiv cov dej noo thiab cov pa oxygen los ntawm kev nkag mus rau hauv cov hlau hauv paus, ua kom qeeb qeeb ntawm kev xeb.
Piv nrog rau cov pa roj carbon zoo tib yam xws li A36, ASTM A588 muaj kwv yees li 2-8 npaug ntawm huab cua corrosion kuj zoo dua, nyob ntawm tej yam kev mob xws li av noo, salinity, thiab muaj kuab paug. Hauv kev siv sab nraum zoov feem ntau, nws tuaj yeem txo qis lossis txawm tias tshem tawm qhov kev xav tau ntawm kev tiv thaiv txheej txheej tsis tu ncua.
ASTM A588 steel phaj feem ntau muaj qhov tsawg kawg nkaus lub zog ntawm kwv yees li 345 MPa (50 ksi qib) thiab muab cov qauv kev ruaj ntseg ruaj khov. Thaum lub sij hawm, nws tsim ib tug txawv reddish - xim av tej yam ntuj tso huab cua zoo li, ua tau ib tug zoo sib npaug ntawm kev ua tau zoo thiab architectural aesthetics.

Dab tsi yog qhov txawv ntawmA588 Corten Phajthiab A36 carbon Steel Phaj?
Qhov sib txawv tseem ceeb ntawm ASTM A588 steel phaj thiab ASTM A36 steel phaj nyob rau hauv cov ntsiab lus alloying thiab cov yam ntxwv ua tau zoo. ASTM A588 yog siab- zog qis- alloy weathering steel nrog ntxiv tooj liab (0.20–0.40%), chromium (0.40–0.65%), thiab nickel (0.25–0.50%) piv rau cov pa roj carbon zoo tib yam.
Yog li ntawd, piv nrog A36, A588 feem ntau muaj kwv yees li 2-8 npaug siab dua atmospheric corrosion kuj (nyob ntawm tej yam kev mob xws li av noo, salinity, thiab muaj kuab paug). Nyob rau hauv tej yam ntuj tso raug, nws muaj peev xwm tsim ib tug ntom thiab ruaj khov txheej tiv thaiv xeb, txo los yog txawm tshem tawm qhov yuav tsum tau rau txheej txheej.
Nyob rau tib lub sijhawm, A588 muaj qib siab zog, nrog qhov tsawg kawg nkaus lub zog ntawm 345 MPa (50 ksi), thaum A36 muaj txog 250 MPa (36 ksi).
Raws li qhov tshwm sim, ASTM A588 yog qhov tsim nyog rau choj engineering, sab nraum zoov steel qauv, lub tsev facades, thiab ntev - lub sij hawm raug cov qauv siv, whereas ASTM A36 yog ib tug dav carbon structural steel tsuas yog siv rau kev tsim kho, mechanical qhov chaw, thiab tsis yog -corrosive structural applications.
