Cov ntawv thov ntawm Tuam Tshoj GB / T 4171 Q460Nh huab cua tiv taus steel phaj
Q460Tnn Huab Cua Tiv Thaiv Hlau Phaj Cov qauv dav dav, haum rau sab nraum zoov qauv uas xav tau lub zog siab thiab ntev -} atmmeric corrosion ..
Nyob rau hauv kev thauj mus los hauv kev lag luam, nws feem ntau siv rauLub tsheb underfrigrames, cov ciav hlau wagon lub cev, thiab choj thauj khoom - cov kabmob sib xyaw, nrog cov cuab yeej siv cov khoom siv tau nrog rau apaib lub zog ntawm kwv yees li 460 MPa, tensile lub zog ntawm 570-690 MPa, thiab elongation 18-22%, tswj hwm kom zoo heev thiab kev ntseeg tau txawm tias hauv qis - kub lossis noo ib puag ncig.
Hauv kev tsim kho cov dej num, Q460nd hlau daim hlau tau thov rauChoj lub ntsiab kab teeb, ntauwd txhawb nqa, lub tsev loj loj ua haujlwm, thiab cov cladorative zoo nkauj.
Lub nthab nthab ibNtse oxide txheej kwv yees li 50-100 μm tuab, uas ua rau qeeb qeeb ntxiv corrosion, muab ibKev Pab Lub Neej ntawm 20-30 xyoosHauv nroog lossis cov chaw muaj txuj ci thiab dhau mus25 xyooNyob rau hauv ntug dej hiav txwv lossis siab - av noo tej yam kev mob.
Tsis tas li ntawd, Q460nd hlau daim hlau tau dav siv nyob rau hauvThawv tsim, shrbuilding, thiab cov chaw sab nraum zoov lojCov. Ua tsaug rau lawv lub zog siab, corrosion tsis kam, thiab me me kev xaiv, lawv yog qhov kev xaiv txhim khu kev qha ntawm cov cua sov ntawm engineering thiab kev siv cov ntawv thov.
