Khoom Description
Corten steel, tseem hu ua Weather Resistant steel lossis Atmospheric Corrosion Resistant steel, nws yog lub npe hu ua tus nqi qis thiab cov khoom siv zoo heev.
Corten steel yog suav tias yog "tus kheej - tiv thaiv" hlau rau nws "patina" uas tshwm sim los ntawm kev tiv thaiv nto oxidation thiab tsim thaum raug rau huab cua; Cov txheej txheem oxide uas muab cov hlau nws qhov txawv txav thiab txhim kho huab cua tiv taus lub peev xwm piv rau cov qauv hlau, thiab kev txhim kho corrosion tuaj yeem ua rau kev ua haujlwm zoo dua qub.
Cov yam ntxwv rau cov hlau no: Qhov saum npoo yuav xeb tom qab qee hnub, tab sis yuav tsum siv sij hawm ib ncig ntawm 3 Lub Hlis; Tsis tas li yog tias koj xav kom nws xeb sai heev raws li lub tsev yuav tsum tau ua, peb tuaj yeem ua cov txheej txheem xeb hauv peb lub rooj cob qhia, ua tiav zoo heev thiab xim tuaj yeem khaws 3-5 xyoos;

FAQ
Q: Cov khoom siv ASTM A709 yog dab tsi?
A: ASTM A709 yog tus qauv tshwj xeeb rau Cov Hlau Hlau rau Cov Txuas Txuas thiab suav nrogcarbon, siab-lub zog qis- alloy, thiab quenched thiab tempered alloy steels siv los ua cov qauv phaj hauv kev tsim cov choj. SSAB muaj tsib qib nram qab no ntawm A709; 36, 50, 50W, HPS 50W thiab HPS 70W.
Q: Qhov txawv ntawm corten thiab A606 yog dab tsi?
A: A606-4 yog hu ua Corten® lossis weathering steel. Nws yog ib hom ntawm lub zog siab uas tsis tshua muaj hlau hlau uas paub txog nws cov tsos zoo li xeb. A606-4 yog qhov nrov vim nws tuaj yeem ua rau cov vov tsev hlau thiab cov vaj huam sib luag. Nws pib tawm unrusted thiab yuav xeb nrog rau huab cua.
Q: ASTM tus qauv rau corten steel yog dab tsi?
A: ASTM specifications yogA588, A242, A606-4, A847, A871-65 thiab A709-50W. Cov khoom lag luam tseem ceeb yog Cor-ten®. Kev xaiv ntawm ib qho tshwj xeeb ASTM weathering steel specification yog nyob ntawm seb yam khoom xav tau. ASTM A588 npog cov qauv duab, phaj, thiab bar.
Q: Qhov txawv ntawm ASTM A36 thiab A709 yog dab tsi?
A: ASTM A709 qib 36 yog cov khoom siv choj uas muaj cov pa roj carbon ntxiv rau lub zog thiab hardenability ntawm cov hlau.A36 muaj tsawg dua 0. 30% carbon thiab yog li, tsis muaj siab hardenability. ASTM A709 qib 36 steel phaj tau txhim kho corrosion kuj thiab tuaj yeem siv rau sab nraum zoov.
Q: Qhov txawv ntawm ASTM A572 thiab ASTM A709 yog dab tsi?
A: ASTM A709 steel qib feem ntau tau teev nrog Charpy cov kev ntsuam xyuas xa mus rau thaj chaw tshwj xeeb lossis qis tshaj qhov kev cia siab rau qhov kub thiab txias. ASTM A572 steel phaj yog lub zog siab qis alloy hlau pom zoo rau riveted, bolted, lossis welded qauv.
