Umbhobho we-321 Stainless Steel vs 304: Xa i-Titanium Stainless Stainless

Intshayelelo

Ukukhetha phakathiUmbhobho we-321 Stainless Steel vs 304ikakhulu ngumbuzo wokuvezwa kubushushu, imeko yokuwelda kunye nomngcipheko wokugqwala phakathi kweegranular. Umbhobho wentsimbi engagqwaliyo we-304 ufanelekile kwiipayipi ezixhathisa ukugqwala ngokubanzi, ukulungiswa kokutya, iinkqubo zamanzi kunye nokuveliswa okuqhelekileyo. Umbhobho wentsimbi engagqwaliyo we-321 ukhethwa xa umbhobho ubekwe kubushushu obuphezulu, ukujikeleza okuphindaphindiweyo kobushushu okanye inkonzo yokuwelda apho ukuzinza kwe-titanium kunceda ukunciphisa uvakalelo lwe-chromium carbide.

Izinto ezibalulekileyo ekufuneka uziqwalasele:I-304 inika ukusebenza kakuhle kweendleko kunye nokufumaneka ngokubanzi kwesitokhwe kwinkonzo esemgangathweni. I-321 yongeza i-titanium, eqinisa ikhabhoni kwaye iphucule ukusebenza emva kokuwelda okanye ukuvezwa ixesha elide kuluhlu lokuvavanya. Kwimibhobho yokutshintsha ubushushu, izinto ze-furnace, iinkqubo zokukhupha umoya kunye nemigca yeekhemikhali ezinobushushu obuphezulu, i-321 inokubonelela ngokuthembeka okungcono kwexesha elide.

Yintoni i-321 Stainless Steel Pipe?

Umbhobho wentsimbi engagqwaliyo i-321 ngumbhobho wentsimbi engagqwaliyo e-austenitic eqiniswe nge-titanium. Kwikhemistri eqhelekileyo ye-321, i-titanium yongezwa kwinqanaba elilawulwayo ukuze idityaniswe nekhabhoni ngokulula kunokuba injalo i-chromium. Oku kunceda ukugcina i-chromium ifumaneka kwi-matrix, ixhasa ukumelana nokugqwala kufutshane neendawo ezitshisiweyo okanye emva kokuvezwa kumaqondo obushushu aphezulu.

Umbhobho wentsimbi engagqwaliyo i-304 nawo uyasebenza kakhulu, kodwa awunayo i-titanium stabilization. Unika ukumelana nokugqwala, ukuwelda kunye nokusebenza kakuhle kokwenziwa. Xa umbhobho usebenza kubushushu obuqhelekileyo okanye ungachaphazeleki kwiimeko zokuziva, i-304 ihlala yenye yezona ntlobo zemibhobho engagqwaliyo ezisetyenziswa kakhulu.
