Kukho umahluko okhoyo phakathi kwe-304 yentsimbi engenasitayile kunye nentsimbi engenasiseko.
Okokuqala, iimpawu zababini zahlukile:
1. Iinxalenye zentsimbi ezingama-304 ze-304 zentsimbi: 304 Intsimbi engenasibala yinto eqhelekileyo kwintsimbi engenasimo, kunye nokuxinana kwe-7.93G / cm³ nakwabizwa ngokuba yintsimbi ye-18/4. Ukunyangwa kobushushu obuphezulu kwe-800 ℃, ineempawu zokusebenza kakuhle zokusebenza kunye nobunzima obuphezulu.
2. Iimpawu zensimbi ye-austicoitic: Ukongeza ekuxhaphazweni kwe-corrosion ye-oxidic acid, i-phosphoric acid, i-phosceric acid, i-ACECH ACID, iqulethe i-TI kunye ne-ti, Ukuxhathisa kwi-insosion engaphakathi kunokuphuculwa kakhulu. Intsimbi ephezulu yeSilicon Austicon Austeritic i-Stainess ye-Staine inesibindi sokunyanzelwa kwe-nitric acid.
Okwesibini , ukusetyenziswa kwezi zimbini zahlukile:
1. Ukusetyenziswa kwentsimbi ye-304 ye-304 ye-stain: ilungele ukuqhubekeka kokutya, ukugcinwa kunye nokuhamba. Inendlela elungileyo yokusebenza kunye nokuqhekeka. I-Plates Head Priser, i-Bulbs, iimveliso zasekhaya (iklasi ye-1 ne-2 yetafile, imibhobho yendawo, ii-bolebs, iibhastile); Iinxalenye ezenzekelayo (i-Windshield Windhers, iiMveliso zeMveliso), izixhobo zonyango, izinto zokwakha, ezolimo, amalungu enqanawa, njl.
2. Ukusetyenziswa kwensimbi ye-austitic ye-austenitic: isetyenziswe ngokubanzi kumzi-mveliso kunye neshishini lokuhombisa ifenitshala kunye neshishini lokutya kunye nezamashishini. Ngenxa yepropathi ebanzi nefanelekileyo yentsimbi ye-austititic ye-austitic engapheliyo, isetyenziswe ngokubanzi kumashishini ahlukeneyo.
Okwesithathu, la macandelo mabini ahlukile:
1. Ukwahlula-hlulwa kwentsimbi engama-304: Zininzi iindlela zokuhlelwa kwentsimbi ezingama-304 zentsimbi, eyokuqala yi-pipe yentsimbi ye-Welded kunye neyona ndlela iphambili yentsimbi ye-304 yentsimbi yeStraid yeSub. Omnye ukwahlulwa komgangatho wesizwe, umgangatho waseJapan, umgangatho waseMelika njalo njalo.
2. Ukwahlulahlulwa kwentsimbi engenasitali i-austenatic Kwimeko yomxholo ophantsi we-C, umxholo we-CR yi-18% ~ ~ 28%, kunye nomxholo we-NI une-3% ~ 10%. Ezinye izitho ziqulatha izinto ezinjenge-MO, cu,,, ti, ti, kunye n.
Olu hlobo lwensimbi luneempawu zentsimbi ezingenasitayile. Xa kuthelekiswa nobuqili, ineepristrations eziphezulu kunye nobushushu, akukho bhetha yegumbi, kwaye iphucule kakhulu i-Brigranness, kwaye iphucule kakhulu ukuxhathisa i-Porrosion kunye nokusebenza kwe-welding.
Kwangelo xesha, ikwagcina i-475 ℃ i-Brittletlet kunye nokuqhubela phambili kwentsimbi ephezulu ye-Ferrict, kwaye ineempawu zodonga. Xa kuthelekiswa nentsimbi engenasitali engenasibala, inamandla aphezulu kwaye kwaye ibaluleke kakhulu ukumelana nokuchasana nokungakhathali kunye ne-chloride uxinzelelo. Intsimbi engenasibala i-staighx inobugwenxa obugqwesileyo kwaye ikwayintsimbi engenasiseko engenanto.
Khetha I-Hingao Tech (Matshini weSeko) Inqaku eliphezulu le-pieli le-pieli le-pildion ye-pild ye-pieed ye-pielitic tube ye-tube ye-tube ukuphatha ukuveliswa kwemveliso yentsimbi ye-304 kunye ne-austetitic yentsimbi yentsimbi yentsimbi ngaxeshanye. Isakhiwo seArchway kunye ne-roller inyanzelekile ukuba inciphise ukuqeshwa kweshafti kwaye iphucule kakhulu ukuchaneka kombhobho wentsimbi. Icandelo leWelding linokusebenzisa ibhokisi ye-welding yegesi yokunciphisa i-oxidation kwaye ufumane umgangatho ophezulu weldal.
