Dab tsi yog qhov coefficient ntawm thermal expansion ntawm 1.4404 stainless hlau yeeb nkab?
Tso lus
Thaum tsim cov kav dej rau kev ua tshuaj, tsim hluav taws xob, khoom noj khoom haus & dej haus, thiab kev siv dej hiav txwv, kev nkag siab txog cov coefficient ntawm thermal expansion (CTE) ntawm cov kav hlau stainless yog qhov tseem ceeb. Kev tso cai tsis raug rau thermal expansion tuaj yeem ua rau cov yeeb nkab deformation, kev nyuaj siab concentration, to, lossis txawm tias lub cev tsis ua haujlwm.
Kab lus no muab cov ntaub ntawv qhia meej, -rov qab piav qhia ntawm thermal expansion coefficient ntawm 1.4404 stainless hlau yeeb nkab, nrog rau kev nkag siab txog engineering thiab cov qauv tsim qauv.
🔹 Dab tsi yog qhov coefficient ntawm thermal expansion ntawm 1.4404 stainless hlau yeeb nkab?
Nyob rau hauv qhov chaw siab - qhov kub thiab txias, 1.4404 stainless hlau kav nthuav ntau dua li cov kav dej carbon steel. Yog tias qhov kev nthuav dav no tsis raug tswj xyuas kom zoo, nws tuaj yeem ua rau: kev ntxhov siab ntau dhau ntawm cov welds, yeeb nkab buckling lossis misalignment, flange to, thiab ua tsis tiav ntxov ntxov.
🔹Coefficient ntawm Thermal Expansion ntawm 1.4404 Stainless Hlau Yeeb Nkab
| Qhov kub thiab txias | Coefficient ntawm Thermal Expansion (CTE) |
|---|---|
| 0-100 ° C | 16.0 × 10⁻⁶ / ° C |
| 20-200 ° C | 16.5 × 10⁻⁶ / ° C |
| 20-300 ° C | 17.0 × 10⁻⁶ /°C |
Qhov chaw:EN cov ntaub ntawv cov ntaub ntawv & ASTM cov nqi siv rau 316L stainless hlau.
Cov ntsiab lus tseem ceeb:1.4404 stainless hlau kav pov thawjkuj siab thermal expansion, ib txwm ntawmaustenitic stainless hlau.
🔹 Yog vim li cas Thermal Expansion Matters hauv Pipe Design
Nyob rau hauv siab - qhov kub thiab txias, cov kav hlau stainless nthuav ntau dua li cov kav dej carbon steel. Yog tias qhov kev nthuav dav no tsis raug tswj xyuas kom zoo, nws tuaj yeem ua rau: kev ntxhov siab ntau dhau ntawm cov welds, yeeb nkab buckling lossis misalignment, flange to, thiab ua tsis tiav ntxov ntxov.
🔹 Piv txwv suav
Yog hais tias ib tug 10 m ntev 1.4404 yeeb nkab yog rhuab los ntawm 20 ° C mus rau 200 ° C:
Yuav luag 30 hli ntawm kev nthuav dav yuav tsum tau haum rau hauv kev tsim qauv.
🔹 Puas yog 1.4404 haum rau siab -cov kav dej kub?
Yog lawm. 1.4404 cov kav hlau tsis muaj steel ua tau zoo txog li ~ 450 ° C hauv kev pabcuam txuas ntxiv, muab thermal expansion yog tswj kom zoo.
🔹 Puas yog txoj kab uas hla ntawm cov yeeb nkab puas cuam tshuam rau thermal expansion?
Tsis yog. Kev nthuav dav nyob ntawm qhov ntev, qhov kub thiab txias hloov, thiab CTE, tsis yog txoj kab uas hla.
🔹 Puas yog 1.4404 nthuav dav siab dua 316?
Tsis yog, qhov thermal expansion ntawm 1.4404 (316L) tsis siab tshaj 316 (1.4401); lawv xyaum zoo tib yam. Ob leeg yog austenitic stainless hlau nrog yuav luag zoo tib yam lub cev lub cev, nrog rau qhov ntom ntom, thermal conductivity, thiab thermal expansion . 1.4404 tsuas yog qhov qis -carbon (316L) European tsim, muab kev zoo dua weldability.
🔹1.4404 vs. Lwm yam Stainless hlau kav: thermal expansion
| Khoom siv | CTE (× 10⁻⁶ /°C, 20–100°C) |
|---|---|
| 304 / 1.4301 | ~17.3 |
| 316L / 1.4404 | ~16.0 |
| 904L | ~15.8 |
| TIAB SA 2205 | ~13.0 |
| Carbon Steel | ~12.0 |
