Cov qeb S355555555555555555555555555555555555555-}} cov hlau roj carbon steel paub zoo rau nws cov khoom zoo tensile. Qeb S3555jo muaj ntau yam nta uas qhia tau zoo rau corrosion thaum lub sij hawm vuam. Lub tshuab luam ntawv yog tib yam li cov qauv me me, thiab cov qib no muaj ntau yam kev siv xws li kev sib tw, lub zog, daj zoo, thiab lwm yam. Cov phiaj muaj cov qauv sib txawv xws li cov paib, roiled, rhawv duab, cov phiaj xwm, cov phiaj xwm}}}} ki} kew hom, thiab ntau lwm yam thiab. Peb tsim khoom thiab cov khoom lag luam raws li cov neeg siv khoom xav tau.
Cov txheej txheem steel s3555jo steel phaj muaj cov ntsiab lus muaj roj carbon tsawg. Yog li ntawd nws tau yooj yim welded thiab muaj lub zog siab tensile. Lub phaj tseem muaj npe rau nws cov vaj tse siab ua tau cov cuab yeej, zoo siv lub zog, ductility, thiab tawm lub zog. Cov phiaj qhia cov khoom zoo thermal thiab conductivity ntawm kev nce kub. Cov paib muaj siab tiv taus oxidation thiab crevice, thiab pitting. Daim ntawv thov ntawm s3555jo daim hlau yog - Kuv siv tau dav hauv cov cuab yeej boiler, etc. Cov cuab yeej siv tshuaj, tshuaj lom neeg, thiab ntau lwm cov khoom siv tshuaj lom neeg. Cov qib S355555555555jo tau siv hauv tshuaj, tsiaj txhu ua zaub noj, tsheb siv reactor, muaj zog ntau ntxiv, thiab ntau ntxiv.
S3555jo daim hlau siv nyob rau hauv ntau yam kev lag luam zoo li yooj yim ntawm kev siv yooj yim, kev ntseeg tau, qhov chaw raug, qauv zoo, thiab ntau lwm nta. Peb ua cov kev ntsuam xyuas sib txawv los kuaj xyuas qhov zoo ntawm cov hlau offshoreS355jo daim hlauCov. Yog li no peb siv cov ntawv xeem hauv qab no, kev kuaj ntshav, ntsuas kev siv tshuab, ntsuas kev nyuaj, thiab lwm yam kev kuaj mob ib yam nkaus. Peb muab cov kev pab ntim khoom zoo tshaj plaws.
