304H uMbhobho weNtsimbi eNgatyiwayo

INKCAZO

I-304H i-austenitic insimbi engenasici, ene-18-19% ye-chromium kunye ne-8-11% ye-nickel ene-carbon ephezulu ye-0.08%. Imibhobho ye-304H yensimbi engenasici iyona mibhobho eguquguqukayo kwaye isetyenziswa ngokubanzi kwintsapho yensimbi engenasici. Babonisa ukumelana nokugqwesa okugqwesileyo, amandla amakhulu, ukulula okuphezulu kokwenziwa, kunye nokwakheka okubalaseleyo. Ke ngoko, zisetyenziselwa iintlobo ngeentlobo zezicelo zasekhaya kunye nezorhwebo. I-304H insimbi engenasici inomxholo wekhabhoni olawulwayo we-0.04 ukuya kwi-0.10. Oku kubonelela ukomeleza amandla obushushu obuphezulu, nangaphezulu kwe-800o F. Xa kuthelekiswa ne-304L, imibhobho yentsimbi engatyiwa yintsimbi engama-304H inamandla amakhulu exesha elifutshane kunye nexesha elide lokurhubuluza. Kwakhona, zixhathisa ngakumbi kwi-sensitization kune-304L.

I-304H IIPROPATI ZOMbhobho wentsimbi ENGXINQI

Ezikhankanywe ngezantsi ziimpawu eziphambili ze-304H zemibhobho yentsimbi engenasici ebonelelwa yiArch City Steel & Alloy:

Ukumelana nobushushu:

  • Ifanelekile kwizicelo zobushushu obuphezulu, njengoko inika amandla aphezulu kumaqondo obushushu angaphezu kwama-500°C ukuya kuthi ga kwi-800°C.

  • IBanga lama-304H linika ukuxhathisa okulungileyo kwi-oxidation kwinkonzo yethutyana ukuya kuma-870°C nakwinkonzo eqhubekayo ukuya kuma-920°C.

  • Iba novakalelo kuluhlu lobushushu be-425-860 ° C; kungoko akukhuthazwa ukuba uxhathiso lokutya okumanzi luyafuneka.

Ukuxhathisa ukonakala:

  • Ukuxhathisa okulungileyo ku-corrosion kwindawo ene-oxidizing, kunye ne-acids eyingozi ephakathi ngenxa yobukho be-chromium kunye ne-nickel ngokulandelelanayo.

  • Isebenza ngokufanayo kwiindawo ezininzi ezonakalisayo

  • Isenokubonisa iqondo eliphantsi lokutya xa kuthelekiswa nebakala eliphezulu lekhabhoni lama-304.

Ukuwelda:

  • Idityaniswe ngokulula ngeenkqubo ezininzi ezisemgangathweni.

  • Kusenokufuneka ukuba uhlambe emva kwe-welding

  • I-Anealing inceda ekubuyiseleni ukuxhathisa umhlwa okuphulukene novakalelo.

Iyaqhuba:

  • Ubushushu bokusebenza obucetyiswayo be-1652-2102° F
  • Imibhobho okanye iityhubhu kufuneka zifakwe kwi-1900 ° F
  • Izinto eziphathekayo kufuneka zicinywe ngamanzi okanye zipholile ngokukhawuleza
  • Ibanga le-304H liguquguquka kakhulu kwaye lifom ngokulula
  • Ukubumba okubandayo kunceda ukwandisa amandla kunye nobulukhuni bebanga lama-304H
  • Ukubumba okubandayo kunokwenza i-alloy ibe yimagnethi kancinane

Ukubanomatshini:

  • Iziphumo ezingcono zifumaneka ngesantya esiphantsi, ukuthambisa okulungileyo, ukondla okunzima, kunye nezixhobo ezibukhali

  • Kuxhomekeke ekusebenzeni ukuqina kunye nokuphulwa kwe-chip ngexesha lokuguqulwa.

Izicelo zeBanga le-304H leMibhobho yeNsimbi eNgatyiwayo

Eminye imizekelo yezicelo ibakala 304H eliqhele ukusetyenziselwa zona ibandakanya:

  • Iimveliso zepetroleum
  • Iibhoyila
  • Imibhobho
  • Izitshintshi zobushushu
  • Iicondenser
  • Ukukhupha umphunga
  • Iinqaba zokupholisa
  • Iiplanti zokuvelisa umbane
  • Ngamanye amaxesha isetyenziswe kwizichumisi kunye nezityalo zemichiza
