Cov qauv thiab cov qauv khoom
Inconel 625 yeeb nkab tsis yog ib daim ntawv tsim khoom. Nyob ntawm txoj kab uas hla, txoj kev tsim khoom, thiab kev siv kawg, nws tuaj yeem poob rau hauv ntau qhov ASTM specifications.
| Txuj | Daim ntawv khoom | Hom Loj Loj | Siv dav |
|---|---|---|---|
| ASTM B444 / ASME SB444 | Seamless thiab welded npib tsib xee-chromium-molybdenum-columbium alloy yeeb nkab | NPS ½ "- 16" (DN 15 - DN 400) | Cov txheej txheem piping, cua sov exchangers, qaub kev pab cuam |
| ASTM B705 / ASME SB705 | Welded nickel alloy yeeb nkab | NPS ½ "- 24" (DN 15 - DN 600) | Loj - kab kab, tus nqi- cov haujlwm tseem ceeb |
| ASTM B704 / ASME SB704 | Welded raj nrog cov kev xav tau ntxiv | OD 6 mm - 219 mm | Condenser, instrumentation, tswj kab |
| ASTM B751 / ASME SB751 | Cov kev cai dav dav rau nickel alloy raj | Ntau yam | Txhawb nqa specification rau B704 / B705 |
| ASTM B829 / ASME SB829 | Seamless npib tsib xee alloy tube | OD 6 mm - 219 mm | Siab -siab tubing, aerospace |

Rau feem ntau refinery, tshuaj, thiab marine daim ntaub ntawv, ASTM B444 seamless yeeb nkab yog lub neej ntawd specification. ASTM B705 welded yeeb nkab raug xaiv thaum xav tau cov kab loj loj lossis cov phab ntsa nyias nyias thiab qhov kev tiv thaiv corrosion ntau dua ntawm lub hauv paus hlau tseem xav tau.
Tshuaj muaj pes tsawg leeg (UNS N06625 / W.Nr. 2.4856)
| Element | Cov ntsiab lus (%) - ASTM B444 |
|---|---|
| Nickel (Ni) | 5 8,0mn |
| Chromium (Cr) | 20.0 – 23.0 |
| Molybdenum (hli) | 8.0 – 10.0 |
| Hlau (Fe) | 5.0 max |
| Niobium + Tantalum (Nb + Ta) | 3.15 – 4.15 |
| Cov pa roj carbon (C) max | 0.10 |
| Manganese (Mn) max | 0.50 |
| Silicon (Si) max | 0.50 |
| Phosphorus (P) max | 0.015 |
| Sulfur (S) max | 0.015 |
Cov ntsiab lus niobium yog qhov txawv ntawm Inconel 625 los ntawm austenitic stainless hlau. Niobium stabilizes weld hlau thiab tshav kub- thaj tsam cuam tshuam tiv thaiv kev puas tsuaj, uas yog vim li cas Inconel 625 ua tau zoo nyob rau hauv raws li -welded mob yam tsis muaj post-weld heat treatment nyob rau hauv feem ntau daim ntaub ntawv.
Mechanical Properties - Qib 1 vs Qib 2
ASTM B444 txhais ob qib. Qhov kev xaiv ntawm lawv yog kev lag luam - tawm ntawm lub zog thiab corrosion kuj.
| Khoom | Qib 1 (Annealed) | Qib 2 (Kev daws teeb meem) |
|---|---|---|
| Kev kho cua sov | Annealed ntawm ~ 871 degree | Cov tshuaj annealed ntawm 1 093 - 1 204 degree |
| Tensile zog, min | 827 MPa (120 ksi) | 690 MPa (100 ksi) |
| Tawm zog (0.2%), min | 414 MPa (60 ksi) | 276 MPa (40 ksi) |
| Elongation, min | 30 % | 30 % |
| Hardness, max HRB | 100 | 100 |
| Hom kev siv | Cov qauv tsim, siab - siv zog | Corrosion-cov txheej txheem kav dej |
Qib 1 yog qhov siab dua - lub zog. Nws yog siv thaum cov yeeb nkab yuav tsum nqa cov khoom siv tseem ceeb thiab corrosion yog qhov thib ob. Qib 2 yog qhov tshwm sim ntau dua rau kev ua tshuaj lom neeg, kev pabcuam dej hiav txwv, thiab qaub vim tias cov tshuaj ntau dua -anneal kub muab qhov zoo tshaj plaws corrosion kuj thiab weldability. Yog tias koj qhov kev qhia tshwj xeeb tsis hu rau qib, feem ntau cov neeg muag khoom yuav hais Qib 2.
Corrosion Performance
| Ib puag ncig | Kev ua tau zoo | Sau ntawv |
|---|---|---|
| Dej hiav txwv | Zoo heev | Resistant pitting, crevice corrosion, thiab chloride SCC; siv nyob rau hauv subsea thiab desalination |
| Cov kua qaub (H₂S) | Zoo | Raws li NACE MR0175/ISO 15156 thaum tswj hardness; txheeb xyuas qhov project txwv |
| Oxidizing acids | Zoo heev | Kev pabcuam nitric thiab sib xyaw acid |
| Txo cov kua qaub | Zoo | Sulfuric thiab phosphoric acid nrog qhov tsim nyog tshaj tawm thiab ntsuas kub |
| Siab -kub oxidation | Zoo rau ~ 980 degree | Kev tiv thaiv Cr₂O₃ nplai; luv- lub sij hawm mus ncig ua si saum toj no 1 000℃ua tau |
