I-304 yentsimbi echanekileyo ityhubhu yentsimbi iluncedo kakhulu, ngakumbi kwishishini lombane, apho inokufumaneka kuyo yonke indawo. Insimbi engenasici inokufumana indawo kwishishini lombane kunye neenzuzo zayo ezimbini zokhuseleko, ucoceko, kunye nokumelana nomhlwa. Nazi ezinye izicelo ezimele.

Okokuqala, amalungu adibana ngokuthe ngqo nokutya. I-304 yentsimbi echanekileyo ityhubhu yentsimbi ilingana "nempompo" njengendawo yokuphuma kwamanzi. Ukudibana ngokuthe ngqo namanzi okusela kubaluleke kakhulu malunga nokhuseleko kunye nococeko lwemathiriyeli. I-304 yensimbi engenasici ibonwa ngurhulumente njengensimbi engenasici. Imvula yeentsimbi ezinzima ezifana ne-arsenic, cadmium, ilothe, ichromium, kunye nenickel ihlangabezana nemigangatho engqongqo. Ngeenkcukacha, nceda ubhekisele kwi-"GB 4806.9-2016 iMigangatho yoKhuseleko lokuTya lweSizwe".

Izixhobo zombhobho zisebenzisa inkqubo yokupolisha ukususa ubude obugqithisileyo bodonga lwangaphakathi lombhobho weld. Udonga lombhobho lunokugutyungelwa kwimpembelelo yesibuko, oluphucula ukuxhathisa umhlwa kunye nokumelana nokunyuka kombhobho wensimbi engenasici kunye nokususa igrisi ukufezekisa ukucoceka okufunekayo kwibakala lokutya, ngoko ingasetyenziswa ngokuzithemba. I-ductility ye-304 yensimbi engenasici ityhubhu yensimbi echanekileyo yi-δ5 (%) ≥ 40, ubunzima ≤ 201HBW, ≤ 92HRB, ≤ 210HV; Akukho lula ukwaphula xa ugoba, kwaye inokugotywa kuyo nayiphi na i-engile, ngokusebenza okugqwesileyo kokusetyenzwa, ukunciphisa kakhulu izinga lokulahlwa, kunye nokugcina iindleko.

Ukongeza, isetyenziswe njengetyhubhu yokutshintshiselana kobushushu kwizifudumezi zamanzi egesi, ehlala kwindawo ephezulu yobushushu kunye nomswakama ixesha elide, kwaye ineemfuno ezingqongqo zokumelana nokugqwala kunye nokumelana nobushushu obuphezulu. I-304 insimbi engenasici inokumelana nobushushu obuphezulu be-800 degrees Celsius, kunye ne-thermal conductivity yayo (W·m-1·K-1): (100 ℃) 16.3, (500 ℃) 21.5, lolona khetho lungcono kwi-gas water heater heat exchange exchange. imibhobho. Iityhubhu zentsimbi ezichanekileyo ezingama-304 ziphathwa ngesisombululo esikhanyayo, esifudumeza ityhubhu yentsimbi kwiqondo lobushushu eliphezulu kwaye ngokukhawuleza siyipholise, inyibilikise iikhabhidi embuthweni, iphucule ukuxhathisa kokuhlwa kombhobho, kwaye yandisa ubomi benkonzo yobushushu. ityhubhu yokutshintshiselana. Ukupholisa ngokuchanekileyo kusetyenziselwa ukuphucula ukugudiswa kodonga lwangaphakathi lwetyhubhu, ukwenza udonga lwetyhubhu luxhathise ukubola kunye nokulinganisa, kunye nokuphucula ukusebenza kobushushu; intsimbi engatyiwayo kulula ukuyisika kwaye inokwenziwa ibe yimibhobho enodonga olucekethekileyo. Ukongeza ekuphuculeni ukuhanjiswa kobushushu, kunokonga iindleko, kwaye ukusebenza kunye noqoqosho luhlala kunye.

Oku ngasentla kukusetyenziswa kweetyhubhu zetsimbi ezingama-304 kwishishini lombane njengonxibelelwano oluthe ngqo kunye nokutya kunye neityhubhu zokutshintsha ubushushu. Emva kohlalutyo olucacileyo lwezinto eziphathekayo kunye nokusebenza kokucubungula, kufundwa ukuba i-304 i-stainless steel stainless precision tubes ingasetyenziselwa ngale ndlela.
