1.xxxx: Tus "1" thaum pib feem ntau qhia tias nws yog tus hlau.
5662: Cov cim tshwj xeeb no cov ntsiab lus rau cov tshuaj muaj pes tsawg leeg thiab cov khoom.
2. Lub npe nquag: 13crmo4-5
Cov Khoom Siv Hauv1.5662yog sib npaug rau cov npe siv ntau13Crmo4-5(Raws li EN 10216-2).
Cia peb tsoo lub npe no:
13: Qhov feem pua kwv yees ntawm feem pua ntawm chromium (CR) yog 0.13% (nws yog qhov tseeb ~ 1%, cov npe yog keeb kwm).
Crwb: Ob lub ntsiab eroy yogYeebsabthiabMolybdenum.
4-5: Tus "4" yog hais txog Molybdenum cov ntsiab lus (~ 0.4%) thiab "5" txhais tau ib theem zoo lossis hloov.
3.. Tshuaj lom neeg sib xyaw (raug)
| Lub ntsiab | Feem puas |
|---|---|
| Carbon (c) | 0.08 - 0.18 % |
| Silicon (si) | Max . 0.35% |
| Manganese (mn) | 0.40 - 1.00 % |
| Phosphorus (p) | Max . 0.025% |

| Molybdenum (mo) | 0.40 - 0.60 % |
4. Cov yam ntxwv tseem ceeb
Qhov kev sib xyaw ntawm cov ntsiab lus muab 1.5662 hlau nws cov yam ntxwv:
Siab siab-kub lub zog:Nws khaws nws lub zog kho twj siv zog thiab tawm tsam "nkag mus" (qhov tsis txaus ntseeg "
Txhim kho oxidation tsis kam:Cov ntsiab lus chromium cov ntsiab lus ib txheej oxide txheej, txo qhov ntsuas kom ntsuas kub ntawm qhov kub.
Zoo weldability:Nws tuaj yeem muab welded siv cov kev sib tw, txawm tias muaj cua sov ua ntej thiab tom qab weld feem ntau pom zoo kom tiv thaiv cov khoom tawg thiab rov ua cov khoom siv microstructure.
Tougness thiab durability:Nws muaj kev sib txig zoo ntawm lub zog thiab kev sib luag.
5. Cov ntawv thov tseem ceeb
Vim nws cov khoom, 1.5662 Seamless kav yog feem ntau siv nyob rau hauv kev kub kub thiab siab siab ib puag ncig. Cov ntawv thov feem muaj xws li:
Lub zog tiam:Tuber boiles, cov leeg superheatre, thiab siab-siab cov kab hauv pob txha roj hluav taws xob roj.
Petrochemical Kev Lag Luam:Hloov cov kab, txoj hlua cua sov, thiab cov piping hauv kev ua kom huv thiab tshuaj chemical.
Siab Hlab:Rau cov roj av lossis kua ntawm cov kev ntsuas siab thiab kub.
6. Cov Qauv Txheej Txheem
Seamless pipes ua los ntawm 1.5662 yog tswj hwm los ntawm kev kawm tshwj xeeb thiab cov txheej txheem kev xa khoom. Qhov tseem ceeb tshaj plaws yog:
EN 10216-2:Seamless cov hlau tubes rau siab lub hom phiaj - kev mob kev mob - Tshooj 2: Tsis-alloy thiab alloy steel leeg nrog teev cov khoom kub.
Lwm cov qauv sib npaug lossis cov qauv zoo sib xws los ntawm thaj chaw sib txawv suav nrog:
DIN 17175:Ib tug laus dua German tus txheej txheem rau kev ua yeeb yam rau kev nce siab kub.
ASTM A335 P11:Qhov no yog ib qho zoo heev Asmeskas sib npaug. Yog tias koj pom P11 Yeeb Nkab, nws yog qhov sib txuas ntau nrog 1.5662 / 13Crmo4-5.
Lub ntsiab
A 1.5662 Seamless steel yeeb nkabyog achromium-molybdenum alloy steel rajTsim tsis muaj welded seam. Nws yog tshwj xeeb tsim rau kev siv hauvKev kub siab thiab qhov kev pab cuam siab siab, muab lub zog zoo, cov plhuav tawm, thiab kav ntev. Thaum sophing los yog qhia kom meej cov yeeb nkab no, koj feem ntau pom nws hu ua13Crmo4-5thiab nws yuav raug muab rau raws li tus qauvEn 10216-2.
Cov Lus Tseem Ceeb:Rau cov ntawv thov tseem ceeb, ib txwm sab laj cov ntaub ntawv tshwj xeeb thiab cov qauv engineering kom ntseeg tau tias cov yeeb nkab ua kom tau raws li qhov xav tau rau koj qhov project.
