Cov feem ntau sib npaug thiab lub npe pom tau rau cov hlau no yogX8crni25-21lossisAISI / UNSENY 310.
1. Cov Khoom Siv Tshwj Xeeb & Tshuaj Siv Tshuaj Ntau Yam
Tus lej "1.5637" yog tusWerkstoffnumummer(Cov Khoom Siv). Nws cov qauv kev tsim yog:
En / din tsim: X 8 crni 25-21
AISI / UNSOLL TSIS TXAUS SIAB: 310S
Lub Npe:25/20 stainless hlau (kwv yees. 25} chromium, 20% npib tsib xee)
Qhov tseem ceeb cov khoom sib xyaw ua ke (raug%):
| Lub ntsiab | Cov ntsiab lus (%) | Lub hom phiaj |
|---|---|---|
| Carbon (c) | Tsawg dua los yog sib npaug rau 0.08 | Cov pa roj carbon tsawg rau kev txhim kho wardability thiab los tiv thaiv cov nag los nag. |
| Chromium (cr) | 24.0 - 26.0 | Muab kev zam tximoxidation thiab scaling Kujthaum kub. |
| Npib tsib caug (ni) | 19.0 - 21.0 | MuabAustenitic qauv, siab {- kub lub zog, thiab kev tawm tsam mus rau carburization. |
| Silicon (si) | Tsawg dua los yog sib npaug rau 1.50 | Nce lub zog thiab oxidation tsis kam. |
| Manganese (mn) | Tsawg dua los yog sib npaug rau 2.00 | AIDS hauv kev ua haujlwm kub. |
| Phosphorus (p) | Tsawg dua los yog sib npaug rau 0.045 | Impurity, khaws qis. |
| Sulphur (s) | Tsawg dua los yog sib npaug rau 0.030 | Impurity, khaws qis. |
| Hlau (FE) | Seem | Lub hauv paus hlau. |
Qhov "S" hauv 310s sawv rau "ruaj khov" lossis cov pa roj carbon tsawg, uas yog qhov tseem ceeb rau nws cov kev ua tau zoo hauv Welded qauv ua haujlwm ntawm qhov kub.
2. Cov yam ntxwv tseem ceeb & Cov Khoom Siv
Seamless pipes ua los ntawm 1.5637 raug xaiv rau lawv qhov kev ua tau zoo tshaj plaws hauv kev xav tau ib puag ncig.
Zoo heev - kub lub zog:Khaws nws cov tshuab muaj zog ntawm qhov kub thiab txias txog 1150℃(2100℃f).
Oxidation zoo tshaj:Lub siab chromium cov ntsiab lus sau ua ruaj khov, tiv thaiv cov txheej txheem oxide uas tiv thaiv kom txog li 1035℃(1900℃f).
Carburization zoo thiab sulfidation Kuj:Ua tau zoo nyob rau hauv cov huab cua nplua nuj nyob rau hauv carbon lossis leej faj, uas muaj ntau yam nyob hauv kev muaj cua sov kom qhuav.
Zoo heev creep:Tsis kam qeeb deformation nyob rau hauv cov neeg muaj kev ntxhov siab thaum muaj kub nyob ntev.
Zoo weldability:Cov pa roj carbon tsawg ua rau nws haum rau vuam tsis muaj qhov xav tau rau cov lus {{weld kev kho cua sov feem ntau.
3. Vim li cas xaiv lub yeeb nkab uas tsis muaj dab tsi?
Lub "kev ua se kev tsim khoom" kev tsim khoom lag luam (qhov chaw tsim khoom yog chob thiab dov rau hauv ib qho yeeb nkab tsis muaj weld seam) yog qhov tseem ceeb rau 1.5637's thov:
Homogeneous qauv:Tsis muaj cov ntsiab lus tsis muaj zog lossis suav nrog uas tuaj yeem tshwm sim los ntawm Weld Kab.
Ntau dua siab ncaj ncees:Superior muaj peev xwm tiv thaiv sab hauv siab, ua kom muaj kev nyab xeeb dua rau cov ntawv thov tseem ceeb.
Zoo dua rau qhov kub thiab kev xeb:Tshem tawm qhov kev pheej hmoo ntawm Weld Seam Seam Ua tsis tiav, uas yog qhov muaj peev xwm kis ntawm kev nres lossis siab {} kev ntxhov siab ib puag ncig ib puag ncig.
4. Cov Ntawv Thov Tib Neeg
1.5637 Seamless kav yog feem ntau siv hauv kev thov cua sov heev thoob plaws ntau yam lag luam:
Kev Kho Cua Sov & Muaj Featnaces:Radiant tub, rov qab, cov muffles, thiab cua sov.
Lub zog tiam:Tube lauj kaub boiles, cov leeg superheatre, thiab siab - kev hloov pauv kub hauv cov khoom thee, roj av, thiab cov nroj tsuag roj ntsha, thiab roj ntsha.
Petrochemical Kev Lag Luam:Ethylene ntes rapes leeg, kho cov leeg roj av, thiab lwm yam siab- kub txheej txheem ntsuas kub.
Aerospace & Automotive:Exhaust systems, afterburner parts, and turbocharger components for high-performance engines.
Thermal Ua:Cheebtsam rau cov hauv caug, ncu, thiab lwm cov khoom siv thermal.
Cov Qauv thiab Muab
1.5637 / 310s Seamless kav yog tsim rau ntau yam qauv thoob ntiaj teb, uas txhais tau qhov ntev, kev ua kom muaj kev ua hauj lwm. Cov Qauv Txheej Txheem muaj suav nrog:
EN 10216-5:Seamless cov hlau tubes rau siab lub hom phiaj - prote} part 5: stainless hlau drooj.
ASTM A312 / A213:Cov qauv kev qhia tshwj xeeb rau kev sib khi thiab welded ustenitic stainless hlau kav / yas.
Sib piv nrog cov qhab nia zoo sib xws
vs . 1.4841 (310 / 310H):1.4841 muaj cov ntsiab lus carbon ntau dua (0.04- 0.10%), uas muab nws dua li cov pa roj av. 310 s (1.5637) yog cov pa roj carbon ntau, ntau weldable version.
vs . 1.4845 (314):314 Muaj ntau dua silicon cov ntsiab lus (1.5-3.0%), muab nws txawm tias zoo dua oxidation tsis kam tab sis ua rau nws nyuaj rau fabricate.
vs . 1.4948 (304h):304h muaj qis dua chromium thiab npib tsib xee (18/8), yog li nws tsis tuaj yeem tiv taus tib yam li huab cua sov li 310s.
