Dab tsi yog cov khoom siv Haynes?

Haynes yog lub npe nrov rau ib pab pawg ntawm cov khoom siv ua haujlwm siab tsim los ntawm Haynes International Inc., uas yog cov chaw tsim khoom ntawm cov khoom kub kub. Cov alloys yog tsim los ua kom pom qhov kub thiab txias zog, oxidation tsis kam, thiab corrosion kuj, ua rau lawv haum rau siv nyob rau hauv huab ib puag ncig xws li dav hlau xyaw, roj turbines, tshuaj ua cov nroj tsuag, thiab nuclear reactors.

Cov ntaub ntawv Haynes yog tsim los ntawm nickel, chromium, thiab cobalt, nrog rau lwm cov khoom xws li tungsten, molybdenum, thiab hlau. Cov alloys paub txog lawv cov khoom tshwj xeeb, suav nrog kev kub siab lub zog, zoo heev tiv thaiv thermal qaug zog, thiab tiv taus kub kub corrosion thiab oxidation.

Haynes alloys yog siv rau ntau yam kev siv, suav nrog aerospace, tshuaj ua haujlwm, tsim hluav taws xob, thiab lwm qhov chaw kub thiab muaj kev ntxhov siab. Qee qhov zoo tshaj plaws Haynes alloys suav nrog Haynes 25, Haynes 188, thiab Haynes 747.

Haynes 25 yog cobalt-based alloy. Haynes 25 yog tsim los ntawm cobalt, chromium, tungsten, npib tsib xee, hlau, thiab lwm yam kab kawm. Nws muaj qhov siab melting point ntawm ib ncig ntawm 1300 degree (2370 degree F) thiab tuaj yeem khaws nws cov khoom siv hluav taws xob ntawm qhov kub txog li 980 degree (1800 degree F). Qhov no ua rau nws tsim nyog siv rau hauv cov roj turbine xyaw, kev siv aerospace, kev lag luam furnaces, thiab lwm qhov chaw kub.

Haynes 25 tseem paub txog nws txoj kev tiv thaiv zoo heev rau oxidation thiab sulfidation. Nws muaj qhov zoo ductility thiab toughness, ua rau nws tsim nyog rau kev tsim thiab vuam txheej txheem. Haynes 25 muaj cov yam ntxwv tshwj xeeb hu ua "galling resistance," uas ua rau nws tsim nyog siv rau hauv cov ntawv thov uas cuam tshuam nrog zawv zawg lossis tig kev sib cuag nrog lwm qhov chaw hlau. Cov yam ntxwv no tso cai rau nws tiv taus cov kev ntxhov siab ntau yam tsis tau tsim kev puas tsuaj los yog hnav.

Haynes188 cobalt-raws li alloy yog ib qho kev daws teeb meem ntxiv dag zog rau cobalt-based superalloy uas tuaj yeem tiv taus ntau hom kev hnav thiab corrosion nrog rau qhov kub thiab txias oxidation. Cobalt-chromium-chromium-tungsten (molybdenum) alloy lossis stellite (Sitae alloy invented hauv 1907). Cobalt alloy yog cov hlau alloy nrog cobalt ua cov khoom tseem ceeb, muaj ntau cov ntsiab lus alloying xws li npib tsib xee, chromium, tungsten, thiab ib qho me me ntawm molybdenum, beryllium, titanium, titanium, beryllium, thiab qee zaus hlau. Nyob ntawm seb muaj dab tsi nyob rau hauv cov hlau, lawv tuaj yeem ua rau vuam hlau. Cov hmoov yog siv rau hauv kev sib tw tawv tawv, thermal txau, tshuaj tsuag vuam thiab lwm yam txheej txheem.

Haynes188 alloy muaj qhov kub thiab txias zog thiab ib puag ncig muaj peev xwm. Haynes188 alloy yog cobalt-nickel-chromium-tungsten alloy nrog high-temperature zog thiab zoo oxidation kuj mus txog 2000F (1095C), ntev raug lub sij hawm, thiab zoo heev tiv thaiv kub corrosion ntawm sulfate deposits. Haynes 188 yog li ntawd yooj yim los tsim thiab tsim rau hauv castings siv cov txheej txheem ib txwm ua. Daim ntawv thov teb: tsim nyog rau kev tsim cov tshuab aero, uas yuav tsum tau muaj zog dua hauv qab 980C thiab xav tau ntau dua los tiv thaiv oxidation hauv qab 1100C. Nws kuj tseem tuaj yeem siv rau hauv cov nkoj loj thiab cov dav hlau dav hlau. Ntau yam khoom deformed tuaj yeem tsim, xws li nyias phaj, nruab nrab phaj, sawb, bar, forging, hlau, precision casting.

Haynes 747 yog Fe-Ni-Cr raws nag lossis daus hardening deformable superalloy. Nws yog siv nyob rau hauv cov tshuaj tov khoom. Lub sijhawm ua haujlwm ntev yog 1100 degree -1250 degree, thiab lub sijhawm ua haujlwm luv luv tuaj yeem ncav cuag 1300 degree . Cov hlau muaj lub zog siab, kev ruaj ntseg zoo, thiab kev ua haujlwm zoo oxidation thiab kev ua haujlwm zoo. Cov hlau muaj qhov zoo weldability thiab tuaj yeem welded los ntawm ntau yam txuj ci. Cov khoom tseem ceeb yog tuav, phaj, kav, xov hlau thiab forgings.

Alloy Haynes daim ntawv thov muaj xws li bar, phaj, raj, hlau thiab forgings. Peb, HT PIPE, tuaj yeem muab Haynes 25, Haynes 188 thiab Haynes 747 yeeb nkab fittings. Txais tos tiv tauj peb kom paub meej cov khoom muag!
