Uhlobo 304 I-Stainless Steel
Uhlobo lwe-304 lusetyenziswa kakhulu kwi-austenitic insimbi engenasinki , kwaye yaziwa nangokuthi "18-8" insimbi engenasici ngenxa yokubunjwa kwayo - iquka i-18% ye- chromium kunye ne-8% ye- nickel .
Uhlobo lwe-304 olungenasici olungenasinxibe luneempawu ezifanelekileyo zokumisa kunye nokunyusa, kunye nokuxhatshazwa okuqinileyo kunye namandla.
Kwakhona kunokonakala okulungileyo. Iyakhiwa ibe yimilo eyahlukeneyo kwaye, ngokungafani nohlobo lwangenasiphatho esingama-302, lunokusetyenziswa ngaphandle kokulunga. Ukusetyenziswa ngokuqhelekileyo kwintsimbi ye-stainless steel type 304 kufumaneka kwicandelo lokutya. Kukulungele ukuphuza, ukusetyenziswa kweebisi kunye nokwenza iwayini, kunye nemibhobho, iipilisi zemvubelo, izitya zokuvumba kunye namathangi okugcina.
Uhlobo lwe-grade ye-stainless stainless 304 lufumaneka nakwiimitha, iipiltops, iiphofi zekhofi, iifriji, izitofu kunye nempahla eyahlukeneyo kunye nezinye izinto zokupheka. Ingakwazi ukumelana nokubola okubangelwa yimichiza eyahlukeneyo efumaneka kwiziqhamo, inyama kunye nobisi. Ezinye iindawo zokusetyenziswa zibandakanya izakhiwo, izitya zeekhemikhali, ukutshintsha kweentsimbi, izixhobo zokumbiwa kweemigodi, kunye neenqanawa zasolwandle, iibhotshi kunye neentloko. Uhlobo lwe-304 lusetyenziswa kwakhona kwiimigodi kunye neenkqubo zokucoca kwamanzi kunye noshishino lokudayisa.
Uhlobo lwe-304L Insimbi Engenasici
Uhlobo lwe-304L olungenasinxibe yintsimbi ekhethiweyo yekhabhoni ye- alloy steel alloy . Umxholo ophantsi kwekhabhoni ngo-304L unciphisa i-carbide imvula yamanzi ngenxa ye-welding. I-304L, ngoko ke ingasetyenziselwa "njenge-welded" kwiindawo ezinobungozi obukhulu kwaye iyakususa isidingo sokususa.
Eli bakala linemihlaba engaphantsi kancinci kunezinga eliqhelekileyo le-304, kodwa ngokuqinisekileyo lisetyenziselwa ukubonga ngokubambisana kwayo. Njengohlobo lwe-304 olungenasipuni, lusetyenziswa ngokusetyenziswa kwebhiya kunye nokwenza iwayini, kodwa nangeenjongo ezingaphaya kwezoshishino ezifana nezitshini zamachiza, ukumbiwa kwezimayini kunye nokwakhiwa. Kukulungele ukusetyenziswa kwimizi yesinyithi efana neentonga kunye neebhontshi eziza kubonakala kwiityuwa zamanzi.
