TusS3555j0w xeb hlau phajthiabS355j2w huab cua hlau phajYog ob qho tib si qib tau txhais tau nyob hauv qab EN 10025-5-5 tus qauv, paub rau lawv lub zog siab thiab lub zog muaj zog thiab atmospheric corrosion.
Ob tugHuab Cua Hlau Phiajtau siv dav hauv cov txheej txheem tshuab vim lawv cov kev ua tau zoo hauv ntau txoj kev nyab xeeb.
Cov tshuaj lom, ob qib kawm sib qhia zoo sib xws POB ZOS (C), MANCANES (MN), phosphorus (cu)
Cov ntsiab lus sib xws no txhim kho cov xeb tsis kam ntawm covCorten Steel Phajlos ntawm kev txhawb nqa kev tsim ntawm lub zog thiab tus nqiRusty Hlau PhajCov txheej tiv thaiv, uas tiv thaiv cov hlau los ntawm oxidation ntxiv.
Qhov tseem ceeb ntawm qhov sib txawv ntawm lubS3555j0w xeb hlau phajthiabS355j2w huab cua hlau phajyog qhov kev cuam tshuam qhov ntsuas kub. J0 Qib (S355J0W) yog sim ntawm 0 degree, thaum J2 qib2W) Undergese xeem ntawm -20 degree.
Qhov no txhais tau tias tusS355j2w huab cua hlau phajMuab cov tawv tawv muaj zog dua ntawm qhov chaw kub qis dua, uas yog qhov tseem ceeb rau cov ntawv thov tuaj yeem tshwm sim sai sai tuaj yeem tshwm sim thaum muaj cov xwm txheej kub.
Hais txog cov khoom siv mechanical, ob qib kawm muaj tsawg kawg lub zog ntawm 355 MPa thiab tensile lub zog puag ncig 470 MPa thiab 630 MPa.
Lawv kuj nthuav tawm cov khoom elongation zoo, feem ntau yog siab dua 20%, uas ua kom muaj zog ua kom txaus rau kev ua thiab cov ntawv thov kev tsim qauv. Cov cwj pwm no ua rau lawv xaiv zoo tagnrho rau cov choj, vaj tse, thiab sab nraum zoov cov qauv qauv.
Ob qho tib siS3555j0w xeb hlau phajthiabS355j2w huab cua hlau phajkuj tso tawm zoo heev weldability.
Cov pa roj carbon tsawg tsawg uas muaj nuj nqis rau kev siv vuam tsis muaj preheating nyob rau hauv ntau yam, uas ua kom yooj yim fabrication thiab txo cov nqi. Welded pob qij txha khaws cov tshuab muaj zog thiab ua kom muaj kev ncaj ncees ntawm lub ntuj corrosion {1} {tiv taus patina.
Nyob rau hauv cov nqe lus ntawm corrosion tsis kam, tusRusty Hlau PhajCov tsos ntawm cov nocorten steel daim hlauyog tsis tsuas yog ib qho kev ua kom zoo nkauj tab sis kuj tseem ua haujlwm ib qho.
Cov ntaub ntawv patina vim muaj tooj liab thiab lwm cov ntsiab lus qub thiab ua haujlwm ua cov thaiv ruaj khov rau ib puag ncig thiab hauv cov khoom lag luam.
Hauv cov ntsiab lus xaus, ob qho tib siS3555j0w xeb hlau phajthiabS355j2w huab cua hlau phajMuab lub zog txhim khu kev qha muaj zog, zoo nruj (nrog J2 zoo dua rau cov mob khaub thuas txias), thiab cov tshuaj tiv thaiv corrosion.
Lawv cov tshuaj lom neeg muaj kuab lom thiab cov kws kho tshuab yog tsim los txhawb nqa ntev {{}} kav ntev hauv ntau qhov kev ua haujlwm sab nraud.
