0.01 - 0.05% |
0.01 - 0.04% |
Titanium tuaj yeem kho cov nitrogen hauv hlau, tiv thaiv kev tsim cov nitrides phom sij thiab txhim kho cov laus tiv thaiv cov hlau. |
Cov Khoom Siv Neeg Kho Tshuab (PSL1 VS PSL2)
Cov cuab yeej ua haujlwm ntawm X52 Steel hauv PSL1 thiab PSL2 specifications kuj txawv, uas yog qhov tseem ceeb rau cov khoom lag luam raws li cov kev xav tau tshwj xeeb.
| Ntiag tug | PSL1 tus nqi | PSL2 tus nqi | Qhov tseem ceeb |
|---|---|---|---|
| Paib lub zog | Ntau dua los yog sib npaug rau 360 MPa | 360 - 525 mpa | Tos lub zog yog qhov kev ntxhov siab uas cov khoom pib kom yauv yooj yim. Cov kev qhia tshwj xeeb hauv PSL2 yog ntau dua, txhawm rau ua tau ruaj khov ntau ruaj khov nyob rau hauv high- qhov kev siv hluav taws xob siab xa hluav taws xob. |
| Lub zog tensile | 460 - 630 mpa | 460 - 760 mpa | Lub zog tensile sawv cev rau qhov kev ntxhov siab tshaj plaws cov khoom siv tau ua ntej tawg. Qhov siab dua qhov txwv hauv PSL2 qhia tau zoo dua lub zog zoo dua qub, haum rau ntau tshaj kev xav tau pipeline ib puag ncig. |
| Elongation | Ntau dua los yog sib npaug rau 20% (gage ntev 50 hli) | Ntau dua los yog sib npaug rau 22% (gage ntev 50 hli) | Elongation pom tias qhov ductility ntawm cov khoom siv. Ib qho siab dua elongation hauv PSL2 txhais tau tias cov ntaub ntawv tuaj yeem nkag siab ntau yam deformation thaum tsim thiab siv yam tsis muaj tawg. |
| Kev Cuam Tshuam | Tsis teev | Ntau dua los yog sib luag rau 27 j ({{-} 20 degree, transverse charpy v-imch) | Kev cuam tshuam cov tawv tawv yog qhov tshwj xeeb tshaj yog rau cov raj kav siv rau hauv cov cheeb tsam txias. Cov kev xav tau meej hauv PSL2 kom paub meej tias cov hlau tuaj yeem tawm tsam brittle fracture nyob rau hauv kev cuam tshuam loads nyob rau hauv qis-}}}} qhov chaw ib puag ncig. |
| Kev nyuaj | Tsis teev | Tsawg dua li lossis sib npaug rau 270 HB (Brinell Hardness) lossis 25 hrc (rockwell hardness) | Lub hardness yuav tsum nyob rau hauv PSL2 pab tswj cov kev coj tsis kam thiab machinability ntawm tus hlau, kom ua tau zoo thaum xa khoom thiab siv. |
Weldability thiab Formability
Zoo heev Weldability
Ob qho tib si PSL1 thiab PSL2 qib ntawm X52 Cov hlau ua pom pom zoo heev Veldability, uas yog qhov tseem ceeb rau kev tsim khoom ntawm cov raj xa dej.
Rau PSL1 X52 Hlau, nws yuav tau welded zoo siv cov txheej txheem vuam xws li phau ntawv arc vuam thiab roj hlau arc vuam. Thaum lub sij hawm vuam, nrog cov ntaub ntawv vuam uas tsim nyog vuam thiab cov tsis muaj zog, zoo Weld zoo tuaj yeem ua tiav yam tsis muaj kev tsis xws luag.
PSL2 X52 Hlau, vim nws txoj kev tswj hwm kev sab nraud, tshwj xeeb tshaj yog cov ntsiab lus muaj roj carbon ntau dua, muaj cov weldability qis dua. Nws yog qhov haum rau ntau cov txheej txheem vuam siab dua xws li submerged arc vuam thiab laser vuam. Txawm nyob rau hauv loj- dex thiab tuab - phab ntsa pipeline vuam, nws tuaj yeem txo qhov tshwm sim ntawm vuam tawg thiab lwm yam teeb meem.
Zoo tshaj formability
X52 Hlau, Seb PSL1 lossis PSL2, muaj cov formatiscity zoo tshaj, uas tuaj yeem ua kom tau raws li kev cai ntawm cov txheej txheem kev ua kom zoo.
Nyob rau hauv lub uoe txoj kev ua cov txheej txheem, uas yog ib txwm siv rau loj- txoj kab uas hla mus rau hauv ib qho, thiab thaum kawg mus rau qhov xav tau ntawm lub taub. Thaum lub sijhawm cov txheej txheem no, cov hlau tswj cov plaster zoo thiab tsis tawg lossis tawg.
Rau cov kauv welded yeeb nkab sib sau, X52 hlau tuaj yeem dov thiab tsim los ua tus kauv duab, thiab cov vuam zoo yog qhov ruaj khov. Nws cov qauv zoo ua kom pom qhov tseeb ntawm cov kauv thiab cov kev ua tau zoo.
