ASTM A242 Corten Hlau Phiaj
Lub ASTM A242 specification yog tus qauv tshwj xeeb rau high- allo} {}}} allo all all {{{{{{{resist resist resist resist resist resistance to to rau kev txo qhov hnyav corrosion. Cov khoom siv neeg kho txhua yam yuav tsum tau teev los ntawm cov khoom lag luam (phaj, bar, thiab ntu ntu) thiab tuab.
ASTM A242 hlau tiv taus atmospheric corrosion.
Steel phaj nyob rau hauv astm A242 tus qauv, tseem hu ua huab cua hlau phaj, yog semi- tawv tawv lossis tawv tawv. Nws muaj qhov zoo tsis kam mus rau cov atmospheric corrosion thiab tuaj yeem siv rau hauv ntau qhov kev ua haujlwm ib puag ncig.
ASTM A242 Weathering Steel ua yeeb yam zoo dua li cov hlau txheem hlau nrog lossis tsis muaj tus tooj liab ntxiv.

ASTM A242 Corten Steel Sheet Hlau Cov Lus Qhia
Qib A242 yog ib qho kub siv cov khoom siv kub nrog kev txhim kho rau cov khoom lag luam atmospheric hauv qab. Cov ntsiab lus tseem ceeb yog cov chromium- npib tsib caug thiab tooj liab, nrog rau tus kheej zoo nkauj- kev tiv thaiv. Thaum tus hlau reacts nrog atmosphericies, dhau sijhawm cov khoom txheej txheej txheej ntawm xeb uas yeej tseem ceeb tiv thaiv cov hlau los ntawm corrosion.
ASTM -} Ua raws li A242 hom1 corrosion - Cov siv hlau tsis kam siv rau cov thawv hlau.
Tsis tas li ntawd, A242 hom1 steel muaj kev txhim kho rau cov ntaub ntawv: kev tsim kho, cov pa taws, cov tsheb nqaj hlau, cov tsheb nqaj hlau thiab choj thiab choj thiab choj thiab choj thiab choj thiab choj thiab choj thiab choj.
Lub alloying ntawm A242 hom1 hlau nrog tooj liab thiab chromium ua kom haum txheej ntawm xeb thiab tib lub sijhawm muab nws lub ntsej muag txaus nyiam.
