Raws li ASTM B444 seamless yeeb nkab qauv, alloy 625 tubing yog ua los ntawm Inconel 625 (UNS N06625) nickel chromium molybdenum columbium alloy. Nickel thiab chromium muab kev tiv thaiv oxidation zoo heev; molybdenum tiv thaiv tsis-oxidative corrosion; thiab niobium stabilizes cov hlau los tiv thaiv rhiab heev thaum vuam.
ASTM B444 nickel alloy 625 seamless tubes muaj zog corrosion kuj thiab siab oxidation kev ua tau zoo, zoo tensile thiab qaug zog zoo los ntawm qis kub mus rau 980 degree, thiab muaj kev ntxhov siab corrosion resistant nyob rau hauv ntsev tsuag ib puag ncig. 625 alloy yeeb nkab muaj qhov tsis tshua muaj corrosion nyob rau hauv dej hiav txwv thiab tsis yog dej hiav txwv ib puag ncig, thiab nws muaj cov seawater corrosion kuj zoo, corrosion kuj mus rau ntau yam ntsev tov, corrosion kuj rau HNO3 phosphoric acid, thiab nws kuj yog heev resistant rau HCl thiab tsawg. -concentration sulfuric acid rhuab mus rau hauv qab ntawm boiling point. Nws tuaj yeem siv los ua cov khoom siv cav, cov khoom siv dav hlau, thiab cov khoom siv tshuaj.
TS muab Inconel 625 seamless high nickel alloy tubes (UNS N06625) ua raws li ASTM B444, uas muaj nyob rau hauv ntau yam ntawm qhov ntev lossis hauv cov lus qhia tshwj xeeb los ntawm cov neeg siv khoom.

Cov txheej txheem kev ua tau zoo thiab cov kev xav tau
Cov hlau muaj qhov txias txias thiab kub ua kom zoo, thiab cov cua kub ntawm steel ingot forging yog 1120 degree.
Qhov nruab nrab grain loj ntawm cov alloy yog ze ze rau lub degree ntawm deformation ntawm forging thiab qhov kawg forging kub.
Lub vuam kev ua tau zoo ntawm cov hlau yog qhov zoo, thiab nws tuaj yeem siv rau argon arc vuam nrog tungsten electrodes lossis ua ib qho ntxiv hauv qhov chaw tiv thaiv. Nws kuj tseem siv tau rau kev sib txuas ntawm brazing thiab kuj seam vuam.
Cov txheej txheem kho deg: Thaum tshem tawm cov nplai ntawm cov hlau nplaum, nws yog thawj zaug ntxuav nrog alkali thiab tom qab ntawd muab tso rau hauv nitric acid lossis hydrofluoric acid-dej tov.
Thaum cov hlau ua haujlwm txias thiab cov nqi ua haujlwm ntau dua 15 feem pua, nws yuav tsum tau muab tshem tawm tom qab ua haujlwm kub.
