Hastelloy C276 Vuam thiab Fabrication Qhia
Hastelloy C276(Tsis muaj N10276) yog npib tsib xee-molybdenum-chromium alloy nrog zoo heev corrosion, tshwj xeeb tshaj yog nyob rau ib puag ncig kev sib cav. Nws yog dav siv nyob rau hauv kev lag luam xws li kev ua yeeb yam, kev tswj qias neeg, tubrog teb, thiab pulp & ntawv. Tsim nyog vuam thiab cov kab lus qhia tau yog qhov tseem ceeb los tswj nws cov khoom siv xeb-resistant.
🔧 Vuam ntawm Hastelloy C276
1. Hwj txwv
Hastelloy C276 muajZoo Weldabilitysiv cov hau kev pom zoo.
Nws yogtiv taus weld lwj(intergranular corrosion) txawm nyob hauv txoj kev welded.
Welded pob qij txha khaws corrosion tsis muaj yam tsis muaj tom qab kev kho cua sov.
2. Pom zoo Vuam Txoj Kev
| Kev ua | Sau ntawv |
|---|---|
| Gtaw (Tig) | Feem ntau; muab cov khoom siv huv si. |
| GMAW (MIG) | Haum rau thicker ntu; Tus nqi tso nyiaj tau zoo. |
| Smig (pas) | Siv rau kev ua haujlwm lossis tuab vuam. |
| Paw (Ntshav Arc) | Rau zoo heev, tswj kev vuam (tsawg dua). |
3. Cov hlau cev quav
Siv cov tub rog sib xyaw hlau:Ernicrmo -4(rau gtaw \/ mig) lossisEnicrmo -4(rau smaw).
Zam kev tsis sib xws los tswj kev ua kom haum corrosion.
4. Kev npaj
Ntxuav lub hauv paus hlauUa kom huv (tsis muaj roj, roj, lossis oxide).
Siv cov cuab yeej mob siab rau hastelloy kom zam kom tsis txhob muaj paug ntawm cov hlau hlau lossis hlau stainless.
5. Vuam Cov Lus Qhia
Ceevcuam tshuam qhov kub hauv qab 150 degree (300 degree f).
Kev sivArgon lossis argon \/ HeliumKev thaiv cov roj av rau Tig \/ mig vuam.
Ua kom tau tiag tiagtxaus los tiv thaivntawm lub hauv paus thiab sab ob sab.
Zam kev ua kom sov ntau dhauTxhawm rau tiv thaiv cov nyom kev loj hlob.
