Khoom Txheej Txheem
GNee Steel Khoom SivAsme Sa588 / sa588m C Carbon thiab tsawg-alloy high-zog steel los xij,Tsim los rau cov ntawv thov tsim qauv uas yuav tsum muaj lub zog siab, kev nruj heev ua tau zoo, thiab cov khoom siv zoo tshaj plaws hauv corrosider.
Cov ntawv no yog siv dav hauv kev tsim kho choj, kev loj hauv cov vaj tse, cov tshuab txhim kho hnyav, thiab lwm yam haujlwm kev sib raug zoo uas muaj kev ntseeg tau thiab cov kev ntseeg siab yog qhov tseem ceeb.
Tshuaj Muaj Tshuaj
| Lub ntsiab | Muaj pes tsawg leeg (wt%) | Sau ntawv |
|---|---|---|
| C (carbon) | Tsawg dua los yog sib npaug rau 0.15 | Paub zoo weldability thiab tawv |
| Mn (manganese) | 0.8 – 1.35 | Txhim kho lub zog thiab cov tawv tawv |
| P (phosphorus) | Tsawg dua los yog sib npaug rau 0.04 | Cov ntsiab lus qis tiv thaiv embrittlement |
| S (Sulphur) | Tsawg dua los yog sib npaug rau 0.05 | Minimizes kev pheej hmoo |
| Si (silicon) | 0.15 – 0.40 | Ua yeeb yam li deoxidizer thiab txhim kho lub zog |
| CU (Tooj) | 0.20 – 0.50 | Txhim kho cov khoom siv hluav taws xob corrospher tsis kam |
| Ni (npib tsib) | 0.25 – 0.50 | Txhim kho qhov tsawg-kub kev nruj |
| CR (chromium) | 0.3 – 0.50 | Ua rau corrosion tsis kam thiab lub zog |
| V (vanadium) | 0.01 – 0.10 | Microalloying Caij Rau Cov Xaws Cov Khaub Ncaws |
Kev xav: Kev sib xyaw ua ke ntawm cov roj carbon tsawg thiab ua tib zoo tswj cov ntsiab lus weldability, muaj txiaj ntsig zoo rau hauv lub sijhawm xav tau.
Cov Khoom Siv Neeg Kho Tshuab
| Tuab (mm) | Yield zog (mpa) | Tensile lub zog (mpa) | Elongation (%) | Charpy V-Notch cuam tshuam kev cuam tshuam |
|---|---|---|---|---|
5 | Ntau dua los yog sib npaug rau 345 |
Ntau dua los yog sib npaug rau 485 |
Ntau dua los yog sib npaug rau 18 |
Yeem, ib qho kev xav tau |
