Kev piav txog
ASME SA588 QIB KUB RAWS RESILLANS RESORDER STEED STEED STEEN ua raws li cov qauv huab cua, cais tawm yog qhov siab - alsoy alleal qauv hlau. Nws cov tshuaj lom neeg muaj pes tsawg leeg muaj pes tsawg tus tooj liab (kwv yees li 0.25-0.40%), kwv yees li 0. xee (kwv yees li 0.20.50%).
Qhov sib ntxiv ntawm cov ntsiab lus alloy no muab cov huab cua zoo heev, ua rau cov neeg kawm maj mam ua kom tiav, yog li muaj kev ncua zoo rau cov txheej txheem corrosion.

Daim Ntawv Thov ntawm SA 588Qib Gr.K Steel Ntawv
Hauv kev thov teb, sa588 k-}}}}} Cov tsheb thauj khoom, cov qauv tsheb nqaj hlau, thiab ntau yam kev ua haujlwm.
Piv txwv li, hauv kev tsheb ciav hlau tsheb ciav hlau, cov neeg thauj khoom ntawm SAU SAU SAU SAU SAU SAU SAU NTAWV UA NTEJ YUAV TSUM 30% ntev dua li cov ua los ntawm cov roj carbon steel.
Lawv ntev -}} lub sij hawm corrosion yog feem ntau tswj tsis pub dhau 0,3 mm / 10 xyoo pom rau cov hlau.
Hauv kev tsim kho choj, siv sa588 gr.k corten steel phaj txo cov txheej sib kho ntau, txuag tau tshaj 25-30% hauv kev txij nkawm txhua 20 xyoo. Nws yog qhov tshwj xeeb rau cov choj hlau txuas ntxiv noo noo, cov kab kub lossis cov chaw muaj huab cua ib puag ncig.
Hauv Thawv Raug, S888 Qeb K Huab Cua Hlau Phaj Ntim (kwv yees li 40%}}
In building structures, the surface rust layer of SA588 hot rolled K-grade steel sheet not only withstands environments with average annual humidity exceeding 70%, but also performs stably in wind-sand and salt-fog regions.
Tom qab 2000 teev ntsev {{{{}} bog kuaj, nws corrosion tus nqi yog tsuas yog ib qho {2} {hais tias Q235 steel. Tsis tas li ntawd, nrog cov txiaj ntsig lub zog muaj zog tshaj 345 MPa, nws siv nyob rau hauv high {}} Cov qauv siv kev siv hlau los ntawm 15-20%, txo qis cov nqi tsim kho.
Dab tsi yog qhov sib txawv ntawm A588 Qib K thiab Sa588 Qib K
Ua tau, cov tshuaj khib nyiab thiab tshuaj ntawm cov hlau yog qhov zoo tib yam thiab tsim qauv yog qhov sib txawv. ASTM, Asmeskas haiv neeg rau kev sim thiab cov qauv tsim qauv uas txhais tau qhov txwv thiab cov tsis muaj nqis ntawm cov khoom lag luam thiab cov hau kev ntawm kev sim khoom.
ASME, Asmeskas haiv neeg ntawm cov neeg kho tshuab engineers, cov ntaub ntawv tshwj xeeb yog siv hauv kev tsim khoom thiab kev tsim cov khoom tshwj xeeb.
Hais Txog GNEE
Gnee tau loj hlob dhau xyoo dhau los mus rau hauv kev sib xyaw steel tuam txhab sib txuas R & D, kev tsim khoom, thiab kev lag luam thoob ntiaj teb. Peb txhawb cov ntsiab cai ntawm "Zoo ua ntej, kev ntseeg siab rau tus kheej,"Tau cog lus los nqa Tuam Tshoj - ua hwm hwm cov steel rau cov khoom lag luam thoob ntiaj teb.
Teb rau ntau cov kev xav tau, GNEE kev ua tsis tau zoo txuas ntxiv nws cov khoom siv cov khoom siv thiab cov peev txheej los muab cov kev pabcuam customized thiab yoog raws kev daws teeb meem.
Seb nws yog cov kws ua vajtsev nyuaj heev lossis cov qauv kev txhawb nqa cov neeg siv khoom nrog cov kws tshaj lij thiab cov qauv nruj kom muaj tswv yim sib xyaw thiab ua haujlwm.
