1. Tus lej "1.7362" {- Cov khoom siv qib
Nov yog aWerkstoff tus lej(Cov ntaub ntawv ntawm tus lej) los ntawm tus qauv GermanDIN EN 10216-2Cov. Tus txheej txheem no npog "Seamless cov hlau txiav rau lub siab lub hom phiaj {}}}} cov khoom siv hlau thiab cov khoom siv kub."
Cov khoom sib raug rau 1.7362 yog:
Din / en kev tsim qauv: 25Cro4
Zoo sib xws / cov qhab nia sib npaug:
AISI / SAE:4130 (American sib npaug, ze rau hauv kev sib xyaw)
UNRESS: K41303
En:1.728 (Qhov no yog lwm qhov, cov qib Europe zoo sib xws, feem ntau tau txiav txim siab txuas ntxiv rau ntau daim ntawv thov)
Cov yam ntxwv tseem ceeb ntawm 25Cro4 (1.7362):
Hom:Qhov qes -} alloy alloy, chromium - molybdenum hlau.
Cov yam ntxwv tseem ceeb:
Lub zog siab:Nws tuaj yeem ua cua sov -} nrhiav (quenched thiab tempered) kom ua tiav lub tensile siab thiab tawm lub zog.
Zoo toughness:Tswj hwm cov kev cuam tshuam zoo.
Zoo creep resistance:Ua tau zoo nyob rau hauv kev ntxhov siab ntau ntawm kev nce siab kub (feem ntau txog li 550-600℃/ 1020-1110℃f).
Zoo weldability:Yuav muab welded nrog cov txheej txheem tsim nyog (feem ntau ua ntej pre - cua sov thiab tshaj tawm {Weld Kev Kho Mob Cua sov yuav tsum tau).
Tshuaj lom neeg muaj pes tsawg leeg (raug%):
| Lub ntsiab | Chromium (cr) | Molybdenum (mo) | Carbon (c) | Manganese (mn) | Silicon (si) |
|---|---|---|---|---|---|
| Zoo siab | 0.90 - 1.20 | 0.15 - 0.30 | 0.22 - 0.29 | 0.60 - 0.90 | 0.10 - 0.35 |
2. "Seamless steel yeeb nkab" -} daim ntawv thiab tsim
Seamless:Cov yeeb nkab yog tsim los ntawm cov khoom siv cylindrical hlau billet. Lub billet yog rhuab thiab ces tho los ntawm lub chaw kom tsim lub raj hollow. Cov txheej txheem no tsim cov yeeb nkab / Tube nrogTsis muaj Welded Seamraws nws qhov ntev.
Qhov zoo ntawm cov kav dej seamless:
Lub zog hnav zoo li:Tsis muaj ntawm lub ntsej muag weld txhais tau tias lub zog thiab kev ncaj ncees yog nyob ib puag ncig tag nrho ib ncig.
Kev Ntsuas Siab Siab Tshaj:Lawv feem ntau muaj zog dua thiab tuaj yeem tiv taus sab hauv siab dua thiab sab nraud.
Kev ntseeg tau:Tsawg pheej hmoo ntawm cov ntsiab lus tsis ua tiav, ua rau lawv zoo tshaj rau cov ntawv tseem ceeb.
Ntsiab lus: Dab tsi yog 1.7362 seamless steel yeeb nkab?
Nws yog ahigh - lub zog, cua sov - molybdenum alloy steel yeeb nkab works nrog tsis muaj ntev weld team, tsim los siv nyob rau hauv high - h siab thiab siab {1}-}}}}} qhov chaw dej khov.
Cov Kev Siv Cov Ntawv Siv
Vim nws zoo ua ke muaj zog, kev ua tau zoo, thiab kub kuj, 1.7362 seamless kav dej yog siv nyob rau hauv kev xav tau cov chaw lag luam:
Roj & Roj Kev Lag Luam:
Downhole tubing thiab casing
Laum Kav
Txheej txheem kav hauv kev ua kom zoo
Lub zog tiam:
Siab -} cov kab hauv cov kab hauv pob zeb roj teeb hluav taws xob
Tub ntxaum thiab cov tub rog sab saud
Automotive thiab Aerospace:
Hydraulic Kab
Txheej txheem sib xyaw (tshwj xeeb tshaj yog nyob rau hauv nws sib npaug aisi 4130 daim ntawv)
Xaim tawb
Neeg Kho Tshuab Engineering:
Hydraulic Thooj Voos Kheej Kheej
High - qhov siab kua thiab roj tshuab
Cov cuab yeej siv tshuab yuav tsum muaj zog - rau - qhov hnyav.
Cov Qauv Muaj Feem
Cov yeeb nkab no yuav raug muab rau raws cov qauv uas qhia meej qhov ntev, kev ua haujlwm, kuaj, thiab tshuaj xyuas. Cov Qauv Txheej Txheem muaj suav nrog:
DIN EN 1026-2:Tus qauv European rau kev sib ceg ntawm cov leeg.
ASTM A519:Txheem rau seamless carbon thiab alloy steel neeg siv tubing (npog AISI 4130).
ASTM A335:Txheem rau seamless ferritic alloy - Cov yeeb nkab steel rau high- cov qib kub zoo li P11).
Thaum xaj lossis siv cov khoom siv no, nws yog qhov tseem ceeb los qhia tau tsis yog qib (1.7362) tab sis kuj yuav tsum muajqho loj(Sab nraud ntawm lub taub thiab phab ntsa tuab),qho ntev, thiab tusTus me nyuam(piv txwv li, li qub, quenched thiab tempered).
