Kuna ku hambana ka 3 exikarhi ka 304 stainless steel na austenitic stainless steel:
Xo sungula, swihlawulekisi swa leswimbirhi swi hambanile:
. Ku tiya ka mahiselo yale henhla ya 800 °C, swina swihlawulekisi swa matirhelo ya kahle ya processing xikan’we na toughness yale henhla.
2. Swihlawulekisi swa nsimbi ya austenitic stainless: Ku engetela eka ku tiya ka corrosion ya oxidizing acid medium, loko yi ri na Mo, Cu na swin’wana swiaki, yi nga tlhela yi lwisana na corrosion ya sulfuric acid, phosphoric acid, formic acid, acetic acid, urea, na swin’wana na swin’wana eka corponular eka muxaka lowu wa nsimbi yi nga ri ehansi ka 0.03% kumbe yi ri na ti ti- High silicon austenitic stainless steel yina corrosion resistance ya kahle eka concentrated nitric acid.Second
leswimbirhi swihambanile:
, kutirhisiwa ka
1. Ku tirhisiwa ka 304 Stainless Steel: Swi lulamerile ku lulamisa swakudya, ku hlayisa na ku fambisa. yi na processability ya kahle na weldability. Swicincana swo hisa swa tipuleti, switolwa swa le kaya, switirhisiwa swa le kaya (Tlilasi ya 1 na 2 swa swibya swa le tafuleni, tikhabinete, tiphayiphi ta le ndzeni, swigwitsirisi swa mati, swigwitsirisi, tibati); Swiphemu swa movha (swisula-swifaniso swa WindShield, Mufflers, Molded Products), Switirhisiwa swa Vutshunguri, Switirhisiwa swo Aka, Tikhemikhali, Vumaki bya Swakudya , Vurimi, Swiphemu swa Swikepe, na swin’wana 304 Stainless Steel i nsimbi ya swakudya leyi nga riki na swilo leyi tiviwaka etikweni hinkwaro.
2. Ku tirhisiwa ka Austenitic Stainless Steel: Yi tirhisiwa ngopfu eka indasitiri na fanichara yo khavisa indasitiri na swakudya na indasitiri ya swa vutshunguri. Hikwalaho ka swivumbeko leswi heleleke na leswinene swa austenitic stainless steel, yi tirhisiwile ngopfu eka ti indasitiri to hambana hambana.
Xa vunharhu, swiyenge leswimbirhi swi hambanile:
. Xin’wana i ku avanyisa ka National Standard, Japanese Standard, American Standard na swin’wana.
2. Ku hlawuriwa ka austenitic stainless steel: austenitic-ferritic duplex stainless steel i nsimbi leyi nga riki na swilo swo bola laha swivumbeko swa austenitic na ferritic swi endlaka kwalomu ka hafu ya yin’wana na yin’wana. Eka xiyimo xa le hansi xa C, nhlayo ya CR i 18%~28%, naswona nhlayo ya NI i 3%~10%. Tinsimbi tin’wana titlhela tiva na ti alloying elements tofana na Mo, Cu, Si, Nb, Ti, na N.
Muxaka lowu wa nsimbi wuna swihlawulekisi swa austenitic na ferritic stainless steel. Loko yi pimanyisiwa na ferrite, yina plasticity yale henhla xikan’we na toughness, kungari na room temperature brittleness, naswona yi antswisile swinene intergranular corrosion resistance xikan’we na welding performance.
Hi nkarhi walowo, yitlhela yi hlayisa 475 °C brittleness xikan’we na high thermal conductivity ya ferritic stainless steel, naswona yina swihlawulekisi swa superplasticity. Loko yi pimanyisiwa na austenitic stainless steel, yina matimba yale henhla naswona yi antswisile swinene ku lwisana na intergranular corrosion na chloride stress corrosion. Duplex stainless steel yina pitting corrosion resistance ya kahle swinene naswona yitlhela yiva nickel-saving stainless steel.
Hlawula Hangao Tech (Michini ya Seko) . High Precision Stainless stainless welded tiphayiphi ta vuhumelerisi layini ya austenitic tube mill machine . ku khoma vuhumelerisi bya nsimbi leyi nga riki na swilo swo bola 304 na tiphayiphi ta austenitic stainless steel welded hi nkarhi wun’we. Xivumbeko xa archway xikan’we na roller bearing swi lulamisiwile kuva swihunguta shaft runout xikan’we naku antswisa swinene ku kongoma ka phayiphi ya nsimbi. Xiphemu xa forming welding xinga tlhela xitirhisa bokisi ro welda ra shielding gas ku hunguta oxidation xikan’we naku kuma weld ya khwalithi yale henhla.
