ASTM B622 seamless thiab welded yeeb nkab suppleir chaw tsim tshuaj paus,tiv tauj pebkom tau txais kev tsocai dawb thiab qauv!
ASTM B 622 2npog siab - cov ntaub ntawv ua tau zoo xws li Hastelloy, uas yog ib qho tseem ceeb rau kev lag luam uas yuav tsum tau muaj kev tiv thaiv corrosion thiab siab - qhov kub thiab txias, suav nrog kev ua tshuaj lom neeg, aerospace, thiab nuclear engineering.
Cov Qib Uas Muaj Kev Pab Los Ntawm ASTM B622
UNS N10276 (Hastelloy C-276):Ntau yam corrosion-resistant alloy, dav siv nyob rau hauv aggressive oxidizing thiab txo ib puag ncig.
UNS N06022 (Hastelloy C-22):Renowned rau superior tsis kam rau pitting thiab crevice corrosion.
UNS N10665 / N10675 (Alloy B-2 / B-3):Tshwj xeeb engineered rau tsis kam mus rau ntshiab txo acids zoo li hydrochloric acid.
UNS N06002 (Alloy X):Muaj qhov tshwj xeeb siab - kub lub zog thiab oxidation tsis kam.
Cov Lus Qhia Tseem Ceeb & Specifications

Strict Chemical Composition Control
| Element | UNS N10276 (C-276) | UNS N06022 (C-22) |
| Nickel (Ni) | Tshuav | Tshuav |
| Molybdenum (hli) | 15.0 – 17.0 | 12.5 – 14.5 |
| Chromium (Cr) | 14.5 – 16.5 | 20.0 – 22.5 |
| Hlau (Fe) | 4.0 – 7.0 | 2.0 – 6.0 |
| Tungsten (W) | 3.0 – 4.5 | 2.5 – 3.5 |
| Cov pa roj carbon (C) | Tsawg dua lossis sib npaug li 0.010 | Tsawg dua lossis sib npaug li 0.015 |
Cov Txheej Txheem Kev Kho Hniav thiab Kev Huv Huv
Pickling:Tshem tawm oxide nplai los ntawm kev kho cua sov thiab passivates saum npoo los txhim kho corrosion kuj.
Bright Annealing (BA):Kev kho cua sov hauv hydrogen- huab cua tiv thaiv. Qhov no ua rau daim iav -zoo li cov xim hlau tsis muaj qhov xav tau rau pickling, txo qhov roughness ntawm qhov chaw.
Roughness Control:Rau siab -purity piping, sab hauv diameters feem ntau polished kom ncav cuag Ra qhov tseem ceeb.
Vuam thiab Fabrication pom zoo
Txawm hais tias ASTM B622 hlab yog seamless, lawv nquag koom ua ke rau hauv cov tshuab ntawm vuam.
Filler hlau:Nws raug nquahu kom siv cov khoom sib txuam lossis "dhau-alloyed" muab tub lim (piv txwv li, ERNiCrMo-4 xaim rau C-276) txhawm rau tiv thaiv qhov poob ntawm corrosion kuj ntawm weld seam.
Kev huv huv:Ua ntej vuam, qhov chaw yuav tsum tau muab tshem tawm ntawm cov roj, sulfur, txhuas, thiab lwm yam tsawg - melting - taw tes cov kab mob kom tsis txhob kub tawg.
Formability:Txawm hais tias muaj kev ua haujlwm siab - tus nqi hardening, ASTM B622 cov raj muaj cov ductility zoo, tso cai rau txias khoov thiab flaring.
