Alloy profile thiab muaj lub luag haujlwm
Inconel 625, kuj tau txheeb xyuas tias Nickel Alloy 625 lossis cov khoom siv nickel {}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} paab {}} Nws tswj hwm lub zog, thiab oxidation stability los ntawm cryogenic tej yam kev mob txog li 1000℃(1832℃f).
Cov qhab nia no tau siv dav hauv cov khoom siv marine, siv tshuaj lom neeg, siv cov qias neeg, thiab lub dav hlau siv hluav taws xob uas muaj kev sib raug zoo yuav tsum ua haujlwm hauv parallel. Its Ni-Cr-Mo-Nb balance creates a self-healing oxide film and suppresses localized attack even in acidic and chloride-rich conditions.
Cov Qauv Tsim Tsim thiab Hlau Hlau Cov Yam ntxwv

Cov nyhuv sib xyaw ua ke ntawm molybdenum thiab niobium tsim kev ua kom muaj zog tsis muaj zog, tso cai yooj yim thaum lub sij hawm ntev thaum muaj kev cuam tshuam thermal. Qhov no microsuels khaws cov nplej zoo thiab txwv tsis pub nplej - ciam teb embrittlement tom qab vuam lossis anealing.
Mechanical reliability nyob rau hauv txhua qhov kub thiab kev ntxhov siab
| Ntiag tug | Metric (min) | Imperial (Min) | Kev piav txog |
|---|---|---|---|
| Lub zog tensile | 827 MPa | 120 Ksi | Tswj kev ncaj ncees rau 870 degree |
| Tos lub zog (0.2%) | 414 MPa | Kua Ksi | Kev tawm tsam deformation nyob rau hauv load |
| Elongation | Ntau dua los yog sib npaug rau 30% | Ntau dua los yog sib npaug rau 30% | Duction zoo tshaj tawm -} Raug |
| Kev nyuaj | Tsawg dua los yog sib npaug rau 95 hrb | Tsawg dua los yog sib npaug rau 95 hrb | Muab cov tshuab luam ntawv thiab muaj peev xwm |
Nyob rau hauv kev pab cyclic, inconel 625 khaws kev qaug zog muaj lub zog thiab seem ruaj khov nrog kev tswj hwm tsis zoo hauv kev tswj hwm oxidation.
Kev Tsim Khoom Thiab Kho Cua Sov
Cov kav dej thiab cov leeg yog tsim los ntawm kub extrusion lossis cool dration thiab tom qab tov kev kawm (1995-2100℃Welded hom yog tsim los ntawm TIG lossis Plasma cov txheej txheem nyob rau hauv cov roj av ras thaiv.
Precision sib sau thiab txias sizing sib zog tswj kev sib dhos phab ntsa sib dhos, thaum lub sij hawm ci thiab ci anealing rov qab ua yeeb yaj kiab. Kev tsim khoom thiab tshuaj xyuas ua rawsASTM B444, B705, thiab B704Cov Qauv.
Corrosion kuj hla xov xwm tshaj tawm
Lub Alloy's Dual kev txiav txim -}}}}}}}}} muab nws dav ruaj khov:
- Dej hiav txwv thiab Chlorides:Resists pitting, thiab kev nyuaj siab - corrosion tsoo.
- Oxidizing acids (nitric, chromic):Chromium preserves oxide adherence ntawm qhov kub.
- Txo cov kua qaub (hydrochloric, phosphoric):Molybdenum tiv thaiv kev tawm tsam hauv zos.
- Sour roj (h₂s):Ruaj khov tiv thaiv sulfide kev ntxhov siab tawg rau roj thiab roj kev pabcuam.
- High - oli olidation:Tiv taus scaling thiab hlau poob rau 1000 degree.
