Austenitic stainless steel ayi nge tiyisiwi hi kuhisa, kambe yinga tiyisisiwa hi cold working deformation (cold work hardening, deformation strelesding), leswinga ta engetela matimba naku hunguta plasticity. Endzhaku ka loko austenitic stainless steel kumbe switirhisiwa (springs, bolts, na swin’wana) swi tiyisisiwa hi cold working deformation, kuna ntshikelelo lowukulu wa processing. Kuva kona ka ntshikelelo lowu swiendla leswaku kuva na sensitivity ya stress corrosion loko yitirhisiwa eka ndzhawu ya stress corrosion, naswona swi khumba vukulu byintsongo bya scale. ku tshamiseka. Ku hunguta ntshikilelo, ku nga tirhisiwa vutshunguri byo hunguta ntshikilelo. - Hiku angarhela, yi hisiwa kuya eka 280 °C ~ 400 °C kuringana 2h ~ 3h kutani yi titimela kumbe yi titimela hiku nonoka. Vutshunguri bya ku hunguta ntshikilelo a byi nge hunguti ntsena ntshikilelo wa xitirhisiwa xa ntirho, kambe byi tlhela byi antswisa ku tiya, matimba na mpimo wa ku olova handle ko cinca ku leha swinene.

Xosungula, nyingiso wufanele ku nyikiwa eka ku hlawuriwa loku ringaneleke ka mahiselo yo hisa eka vutshunguri bya solid solution bya austenitic stainless steel. Eka standard ya material ya austenitic stainless sodium, ndzhawu leyi vekiweke ya solid solution temperature yo hisa yi anamile. Eka vuhumelerisi bya xiviri bya heat treatment, xivumbeko xokarhi xa nsimbi, swilo swofana na content, use environment, possible failure form, na swin’wana, hindlela leyi twalaka hlawula mahiselo ya kahle yo hisa. Hambiswiritano, kufanele ku tekeriwa enhlokweni leswaku mahiselo yo hisa yava yanga e henhla swinene hikokwalaho ka ku n’oka, hikuva mahiselo yo hisa ya vutshunguri bya solution ya le henhla swinene, leswinga endlaka leswaku ti grains ta switirhisiwa leswinga antswisiwa hiku endla forging kuva tikula. Ku rhurhumela ka mavele swi nga vanga vuyelo byin’wana lebyi nga tsakisiki.

Xavumbirhi, nyingiso wufanele ku nyikiwa eka mbuyelo wa vutshunguri bya stabilization eka swivumbeko swa xiyimo xa solid solution. Eka austenitic stainless steel leyingana ti stabilizing elements, swivumbeko swa michini swita tala kuhunguteka loko solution heat treatment yi landzeriwa hi stabilization treatment. Matimba, pulasitiki, na ku tiya swi na xiendlakalo lexi. Xivangelo xa ku hunguteka ka matimba ku nga va leswaku hi nkarhi wa vutshunguri bya ku tiyisisa, elemente yo tiya ya carbide-forming element yi hlangana na khaboni yo tala ku vumba TIC, leswi hungutaka degree yo tiyisisa khaboni eka austenite solid solution, naswona TIC yi ta tlhela yi va eka endlelo ro hisa na ku hlayisa ku hisa. Ti agglomerates ta kula, leswi na swona swina mbuyelo eka matimba.

Xavunharhu, mahiselo yo hisa ya vutshunguri bya stabilization aya fanelanga kuva e henhla swinene, hi xitalo exikarhi ka 850°C na 930°C. Austenitic stainless steel ayifanelanga ku endliwa vutshunguri bya solution yotala, hikuva multiple solution heating yita vanga kukula ka mavele naswona yi khumba hindlela yo biha swivumbeko swa junction material. Hi nkarhi lowu fanaka, ku fanele ku nyikiwa nyingiso eka ku thyakisa hi nkarhi wa ku lulamisiwa. Loko se yi thyakisiwile, ku fanele ku tekiwa magoza yo herisa ku thyakisa. Leswaku ku herisiwa ku antswa ntshikilelo wa intergranular, ku tirhisiwa ka Ku hlayisiwa ka ku hisa Muchini wo tshungula ku hisa loku hatimaka . swi nga tekeriwa enhlokweni. Hikuya hi processing data kusuka eka ti clients ta Hangao Tech (Michini ya Seko), . ku hambana ka mahiselo ya point yin’wana na yin’wana eka ndzhawu yo hlayisa kuhisa yi lawuriwa endzeni ka plus kumbe minus 1-2 degrees Celsius, leswaku kuta tiyisisiwa leswaku nsimbi yinga hisiwa hiku hetiseka, mavele yanga n’okisiwa hiku hetiseka, naswona xivumbeko xo antswa xa metallographic xinga kumiwa.
