Austenitic stainless steel n'ebirungi ebiri mu bright annealing .

Ekyuma ekitali kizimbulukuse ekya Austenitic kikozesebwa nnyo mu nkola ez’enjawulo ez’obwannannyini, ez’amakolero, n’ez’amagye. Esangibwa mu ngeri ez’enjawulo, omuli ebbaala, emiggo, ebipande, obubaawo, emiguwa, ebipande, payipu, ttanka, ebikozesebwa, flanges, n’ebirala ebijingirire.

Ekyuma ekitali kizimbulukuse bwe kiyisibwa mu bbugumu mu kyokero ekya bulijjo, ekirungo kya chromium mu kyuma ekitali kizimbulukuse ekya austenitic kikolagana ne okisigyeni mu mpewo, ne kikola layeri ya okisayidi enzirugavu emanyiddwa nga 'scale.' layeri eno erina okuggyibwamu okuyita mu nkola z’okunyiga.

Bright annealing etuwa enkizo eziwerako ez’amaanyi nga eky’okugonjoola ekirala:

1. Okulongoosa mu byuma
   Bright annealing tekikoma ku kukendeeza ku bukaluba bwa ttanka ez’ekyuma ekitali kizimbulukuse wabula era kyongera ku ductility ne plasticity, ekifuula ekintu eky’angu okukola ekyuma n’okukola ennyo.

2. Enhanced corrosion resistance and surface appearance
   nga emalawo intergranular carbide precipitation, okumasamasa annealing erongoosa okuziyiza okukulukuta era etuwa ekifo ekirabika obulungi. Erongoosa ensengekera y’empeke n’okukakasa obutonde bw’ekyuma ekifaanagana, bwe kityo n’enyweza omulimu n’okuteekateeka ebintu okusobola okulongoosa oluvannyuma.

3. Okukendeeza ku situleesi
   Okuzimba ekitangaala kimalawo okunyigirizibwa okw’omunda okusigadde mu kyuma, ne kikendeeza ku bulabe bw’okukyukakyuka n’okukutuka.

4. Okukendeeza ku oxidation ne decarburization
   okwawukana ku annealing eya bulijjo, ekizingiramu oxidation ne decarburization mu kiseera ky’okubuguma n’okunyogoza, okumasamasa annealing kwewala ebikolwa bino. Kino kikendeeza ku kufiirwa ebyuma n’okukendeeza ku ssente endala ez’okulongoosa.

5. Okuzimba (oxidation-free, corrosion-resistant surface
   bright annealing) kuvaamu ekitundu ekitangaavu, ekitaliimu oxidation nga kiziyiza okukulukuta okw’ekika ekya waggulu. Enkola eno ekoleddwa mu mbeera efugibwa eya haidrojeni ne nayitrojeni, eziyiza okukendeera kw’okwokya n’okukendeera kwa chromium, ekivaamu oludda olulina obuziyiza bw’okukulukuta obulungi okusinga 2B ezimaliriziddwa ezisiigiddwa okutuuka ku ddaala erifaanagana.

6. Okusigala kw’okumaliriza kungulu
   okutangaala annealing kukuuma obugonvu obw’okungulu obuyiringisibwa obw’olubereberye, okutuuka ku kumaliriza okumpi n’endabirwamu. Ku nkola ezisinga obungi, kungulu kuno kuyinza okukozesebwa butereevu awatali kwongera kulongoosebwa.

7. Okukulaakulanya ebitundu eby’enjawulo ebirimu ebifaananyi eby’enjawulo
   Okuva enkola y’okusengejja (annealing process) bw’etakyusa ngulu w’ekyuma, ekitangaala ekitangaavu kisobozesa okusigala kw’ebifaananyi ebiyiringisibwa, okwanguyiza okukola ebyuma eby’enjawulo ebiyiringisibwa mu nnyonta.

8. Okulongoosa obutonde bw’ensi
   Okuzimba ekitangaala kimalawo obwetaavu bw’okusiimuula asidi oba obujjanjabi obufaananako bwe butyo, okwewala okukozesa ebirungo ebikosa nga asidi n’okumalawo obucaafu obukwatagana n’enkola z’okusiika ez’ennono.

Bright annealing nkola ya tekinologiya ey’omulembe era eyamba obutonde bw’ensi ey’okulongoosa ebbugumu, etuusa omutindo gw’ebintu ogw’ekika ekya waggulu era eyamba mu nkola ennungi ey’okukola ebintu.
