Waliwo series bbiri eza austenitic stainless steels .
300 Series Stainless Steel okusinga etegeera ensengekera yaayo eya austenitic ng’eyongerako nickel. Common 304 stainless steel ne 316L stainless steel bya mu lunyiriri luno. Ekyuma ekitali kizimbulukuse ekya 200 Series kidda mu kifo kya manganese ne nayitrojeni mu kifo kya nickel, ate ebirimu nikele bitono nnyo. Ekyuma ekitaliimu buwuka ekya bulijjo ekya 201 n’ekyuma ekitali kizimbulukuse 202 bya muddiring’anwa guno.
300 Series Stainless Steel ye series ennene. Ekika ky’ekyuma ekitali kizimbulukuse ekya austenitic ekisinga okumanyibwa era ekisinga okumanyibwa ye kika kya 304, era ekimanyiddwa nga 18/8 oba A2. Ebintu nga ebintu 304 eby’ekyuma ekitali kizimbulukuse, ebikozesebwa mu kufumba n’ebikozesebwa mu ffumbiro. 316 Series Ekyuma ekitali kizimbulukuse kye kiddako okusinga okubeera ekyuma ekitali kizimbulukuse ekya Austenitic. Nga 300 series, nga type 316, era zirimu molybdenum ezimu okutumbula okuziyiza asidi n’okwongera okuziyiza okulumba mu kitundu (nga pitting ne crevice corrosion).
Okwongerako nayitrojeni mu 200 series kigiwa amaanyi g’ebyuma aga waggulu aga 300 series. Austenitic stainless steels zino za bika 309 ne 310 ku bbugumu eringi erisukka 800°C. Ebifaananyi by’ekyuma ekitali kizimbulukuse ekya 200 series: Wadde ng’okukulukuta kw’amayinja agakulukuta, 200 series tesobola nnyo okusinga 300 series okuziyiza okukulukuta okukulukuta, okubeerawo mu mbeera ezirina obunnyogovu bungi ne chlorine, n’okukulukuta kw’amayinja, ekivaako amazzi okuyimirira n’obutonde bwa asidi omungi. Kino kiri bwe kityo kubanga, okusobola okukendeeza ku bungi bwa nickel, ekirungo kya chromium nakyo kirina okukendeezebwa, bwe kityo ne kikendeeza ku buziyiza bw’okukulukuta.
200 series stainless steels zigumira impact era zikaluba ne ku bbugumu eri wansi. Okutwalira awamu zikaluba era nga za maanyi okusinga ebyuma bya series 300, okusinga olw’ekirungo kyazo ekinene ekya nayitrojeni, ekikola ng’ekirungo ekinyweza. Olw’okuba ebyuma ebiyitibwa austenitic, 200 ne 300 series si bya bbeeyi. Naye, okutondebwa (ductility) kw’ekyuma kya 200 series kuli wansi okusinga okw’ekyuma kya 300 series, wadde nga kino kisobola okulongoosebwa nga kigatta ekikomo.
Alloy 20 (Carpenter 20) ye austenitic stainless steel erimu okuziyiza okulungi ennyo eri heat sulphuric acid n’embeera endala nnyingi ez’obukambwe era etera okulumba ekyuma ekitali kizimbulukuse eky’ekika kya 316. Alloy eraga okuziyiza okulungi ennyo eri situleesi okukutuka mu kufumba 20-40% sulphuric acid. Alloy 20 erina ebyuma ebirungi ennyo era okubeerawo kwa Niobium mu aloy kikendeeza ku kutonnya kwa carbide mu kiseera ky’okuweta. Okusinziira ku mpisa ez’enjawulo ez’ebintu eby’enjawulo, enteekateeka n’ensaasaanya y’ebisenge ebiwanvu nabyo birina okuba eby’enjawulo, olwo okugumiikiriza okutono n’omutindo omulungi ogw’okubumba bisobola okufunibwa. N’olwekyo, Hangao Tech (Ebyuma bya Seko) bulijjo ejja kuwuliziganya nabo ku bipimo eby’enjawulo amangu ddala nga bwe kisoboka, oluvannyuma lw’okufuna okwebuuza okuva mu bakasitoma, okusobola okuwa bakasitoma eby’okugonjoola ebituufu ku bikwata ku Stainless Steel Industrial Pipe Production Line Tube Mill Ebyuma ebituukiriza ebyetaago byennyini eby’okufulumya.
Austenitic stainless steels zisobola okugezesebwa nga ziyita mu kugezesa okutali kwa kuzikirizibwa nga tukozesa enkola z’okukebera eziyingira mu langi, oba okukozesa okugezesa kwa eddy current, naye si mu nkola za magnetic particle inspection.
