ASTM A242 Corten Steel Phaj
ASTM A242 specification yog tus qauv specification rau siab - zog, qis- alloy structural steel rau structural Cheebtsam yuav tsum tau yuag yuag thiab tsis kam mus rau atmospheric corrosion. Cov cuab yeej cuab yeej cuab tam tau teev tseg los ntawm cov khoom lag luam (phaj, bar, thiab seem txheej txheem) thiab thickness.
ASTM A242 Hlau Resistant rau Atmospheric Corrosion.
Hlau phaj raws li tus qauv ASTM A242, tseem hu ua weathering steel phaj, yog semi-hardened los yog tag nrho hardened steel. Nws muaj kev tiv thaiv zoo rau atmospheric corrosion thiab yog li siv tau rau hauv ntau qhov chaw ua haujlwm.
ASTM A242 weathering steel ua tau zoo dua li cov qauv hlau nrog lossis tsis muaj tooj liab ntxiv.

ASTM A242 Corten Steel Sheet Hlau Khoom Paub meej
A242 Type1 steel qib yog cov khoom siv kub dov steel nrog txhim kho kev tiv thaiv atmospheric corrosion nyob rau hauv kev xa khoom. Cov ntsiab lus alloying tseem ceeb yog chromium-nickel thiab tooj liab, nrog rau kev sib ntxiv ntawm phosphorus los muab nws tus kheej zoo- tiv thaiv. Thaum cov hlau reacts nrog atmospheric ntsiab, dhau sij hawm cov khoom tsim ib txheej ntawm xeb uas tseem ceeb tiv thaiv cov hlau los ntawm corrosion.
ASTM-raws li A242 Type1 corrosion-cov phaj steel feem ntau yog siv rau cov thawv hlau.
Tsis tas li ntawd, A242 Type1 steel muaj kev txhim kho kev tiv thaiv atmospheric corrosion nyob rau hauv ntau yam kev siv: kev tsim kho, chimneys, fabrication, tsheb thauj khoom, silos, yees thiab txuas hniav.
Lub alloying ntawm A242 Type1 steel nrog tooj liab thiab chromium ua kom muaj kev ruaj ntseg tiv thaiv txheej ntawm xeb thiab tib lub sijhawm muab nws zoo nkauj zoo nkauj.
