ASTM A242 Weathering steel Product Description
ASTM A242 steel yog cov qauv tshwj xeeb rau cov pa roj carbon thiab qis- alloy, siab - lub zog steel phaj. Qhov kev qhia tshwj xeeb no suav nrog siab - lub zog steel profiles, daim hlau, thiab cov tuav tsim los rau kev siv welded, riveted, lossis bolted.
Nws feem ntau yog siv los txo qhov hnyav los yog txhim khu kev ruaj ntseg ntawm cov hlau tsim, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas tiv thaiv atmospheric corrosion yog ib qho tseem ceeb. Paub tias feem ntau yog Corten steel, ASTM A242 tsim kev tiv thaiv xeb-zoo li zoo li thaum raug huab cua, uas pab tiv thaiv cov hlau los ntawm corrosion ntxiv.
ASTM A242 (COR-TEN® Hlau)
ASTM A242 yog lub zog siab qis- alloy cov qauv hlau tshwj xeeb nrog kev txhim kho atmospheric corrosion kuj thiab kub dua. Qhov kev qhia tshwj xeeb no feem ntau siv tau rau cov phaj hlau los ntawm ib -ib nrab nti hauv tuab.
ASTM A242 feem ntau yog siv rau hauv kev tsim khoom ntawm:
Industrial pa phem pawg
Air Ducts tawm cov khoom siv tswj cov pa phem
Cov dej tank
ASTM A242 tuaj yeem tiv taus qhov kub thiab txias mus txog 800F.
Lub atmospheric corrosion kuj ntawm A242 yog qhov zoo dua li cov pa roj carbon steel xws li A36 thiab A572-50 nrog lossis tsis muaj tooj liab ntxiv. Thaum raug pom zoo rau qhov chaw, A242 yog qhov tsim nyog rau ntau daim ntawv thov hauv qhov tsis muaj xim.

ib 242a588
Muaj qhov sib txawv ntawm ASTM A242 thiab ASTM A588 hauv ntau yam. Nov yog qhov sib piv tshwj xeeb:
Tshuaj muaj pes tsawg leeg
ASTM A242: Nws muaj ib qho me me ntawm cov hlau alloy xws li tooj liab, chromium, thiab npib tsib xee. Cov ntsiab lus no tuaj yeem pab tsim cov yeeb yaj kiab oxide tiv thaiv.
ASTM A588: Dhau li tooj liab, chromium, thiab npib tsib xee, nws kuj muaj cov khoom xws li phosphorus, silicon, thiab vanadium. Cov ntsiab lus no txhim kho cov khoom siv kho tshuab thiab corrosion kuj ntawm cov hlau.
Mechanical Properties
Yield Strength: Qhov tsawg kawg nkaus lub zog ntawm ob qho tib si yog 50,000 psi (345 MPa).
Tensile Strength: ASTM A242 feem ntau muaj lub zog tensile ntau dua. Hauv kev sib piv, lub zog tensile ntawm ASTM A588 yog qhov qis dua.
Corrosion Resistance
ASTM A242: Nws muaj kev tiv thaiv zoo rau atmospheric corrosion thiab haum rau qhov chaw sab nraum zoov. Txawm li cas los xij, nyob rau hauv ib puag ncig marine nrog cov av noo siab thiab siab salinity lossis hauv thaj chaw uas muaj kev ua qias tuaj loj, nws qhov kev tiv thaiv corrosion kuj yuav tsis zoo li ntawm ASTM A588.
ASTM A588: Nws muaj kev tiv thaiv siab dua rau atmospheric corrosion, tshwj xeeb tshaj yog nyob rau hauv huab cua hnyav, xws li marine ib puag ncig, ntug hiav txwv dej, thiab lwm qhov chaw uas muaj av noo thiab siab salinity.
Vuam Performance
ASTM A242: Ordinary carbon steel vuam electrodes tuaj yeem siv rau vuam. Tab sis feem ntau nws raug pom zoo kom ua preheating thiab tom qab-weld kho cua sov kom tiv thaiv cov kab nrib pleb thiab ua kom muaj kev ncaj ncees ntawm cov pob qij txha.
ASTM A588: Vim nws cov ntsiab lus alloy siab dua, kev kho cua sov thiab kev ntxhov siab yuav tsum tau ua thaum lub sij hawm vuam los tiv thaiv kev tawg thiab tau txais cov vuam zoo.
Qhov tshwm sim
ASTM A242: Thaum lub sij hawm dhau los, cov txheej txheem zoo sib xws thiab xeb yuav tshwm sim ntawm nws qhov chaw.
ASTM A588: Cov txheej xeb uas tsim los ntawm nws qhov chaw zoo li zoo nkauj dua thiab muab qhov zoo nkauj ntxhib thiab rustic.
Daim ntawv thov teb
ASTM A242: Nws yog feem ntau siv rau hauv cov qauv sab nraum zoov, xws li cov choj zoo tib yam, lub tsev sab nrauv, lub zog xa hluav taws xob, cov thawv, thiab cov tsheb ciav hlau.
ASTM A588: Nws yog qhov tsim nyog rau cov cheeb tsam uas muaj kev xav tau siab heev rau kev tiv thaiv corrosion, xws li marine txuas hniav, cov tsev nyob ntug hiav txwv, thiab cov khoom siv tshuaj.
Daim duab Display
ASTM A242 steel Cov ntawv thov:
ASTM A242 steel yog dav siv nyob rau hauv ntau yam lag luam, xws li:
Kev tsim kho: Qhov zoo tshaj plaws rau cov khoom siv hauv vaj tse, txuas hniav, thiab lwm yam kev tsim kho vaj tse uas xav tau kev ua haujlwm ntev thiab zoo nkauj.
Art thiab Design: Feem ntau siv nyob rau hauv sculptures, landscaping, thiab architectural nta vim nws tshwj xeeb weathered tsos.
Kev thauj mus los: Siv nyob rau hauv kev tsim cov tsheb ciav hlau thiab cov thawv thauj khoom, qhov kev tiv thaiv ib puag ncig hnyav yog qhov tseem ceeb.

fAQ Txog A242 Corten Steel
Vim li cas A242 daim hlau hu ua weathering steel phaj?
Thaum tsim nyog raug rau cov huab cua, ASTM A242 steel tuaj yeem tsim lub ntuj xeb patina uas tiv thaiv cov hlau los ntawm kev raug mob ntxiv. Cov yam ntxwv no tso cai rau cov hlau siv rau hauv cov xwm txheej hnyav yam tsis tas yuav muaj cov coatings lossis pleev xim rau ntawm nws qhov chaw.
ASTM A242 steel yog ib hom huab cua huab cua, feem ntau hu ua Corten A. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias A242 specification tsuas yog txwv rau cov ntaub ntawv steel nrog lub thickness tsawg dua 4 ntiv tes (100 mm).
Hauv cov ntsiab lus, ASTM A242 steel muaj txiaj ntsig zoo rau nws lub zog, ua haujlwm ntev, thiab zoo nkauj zoo nkauj, ua rau nws muaj kev xaiv zoo rau ob qho tib si kev ua haujlwm thiab kev siv zoo nkauj hauv qhov chaw sab nraum zoov.
ASTM A242 khoom yog dab tsi?
ASTM A242 Hlau yogtus qauv rau qis- alloy structural steelsuas ua rau lawv zoo dua ntawm kev tiv thaiv corrosion thiab kub dua. Qhov no Corten A Steel specification feem ntau tau ntsib los ntawm steel daim hlau uas muaj txog li ib nrab nti tuab. Feem ntau, A242 yog siv los ua cov qauv hlau.
ASTM A242 sib npaug li cas?
ASTM A242 type1 steel daim ntawv sib npaug: ASTM A242 type1 steel ntawv yog cov qib sib npaug li S355J2WP (1.8946) steel hauv EN 10025 - 5 : 2004 tus qauv thiab FE510D1K1 steel hauv UNI tus qauv thiab kuj E35 NFWA4 tus qauv.
