Nei isina simbi iri zvakare magnetic?
304 Stainless simbi ndezve austenitic Stainless simbi. Austenite chikamu kana chidiki chinoshandurwa kuita martensite panguva yekutonhora kushanda. Martensite ndeyemagineti, saka 304 simbi isina waya haina magineti kana zvishoma magineti.

Nei isina simbi ngura?
a. Iyo pamusoro yesimbi isina chinhu yakaunganidza guruva rine zvimwe zvinhu zvesimbi kana zvinongedzo zvekunze simbi zvikamu. Mumhepo ine hunyoro, mvura yakanyoroveswa pakati pezvisungo nesimbi isina simbi inobatanidza maviri kuita bhatiri diki, iyo inotangisa kuita kwemagetsi, Iyo firimu inodzivirira yakanganisika, inonzi electrochemical corrosion.
b. Iko pamusoro kwesimbi isina simbi inoomerera kune muto we organic (senge vise, miriwo, sosi yemudyo, sputum, nezvimwewo), iyo inogadzira organic acid pamberi pemvura neoksijeni, uye iyo organic acid ichatora simbi pamusoro kwenguva refu nguva.
c. Iyo yepamusoro yesimbi isina simbi inoomerera kuacid, alkali, uye munyu zvinhu (senge alkaline mvura uye limeimu inoputika pamadziro ekushongedza), zvichikonzera ngura yemuno.
d. Mumhepo yakasviba (senge mhepo ine huwandu hwakawanda hwe sulfide, carbon oxide, uye nitrogen oxide), ichaumba sulfuric acid, nitric acid, uye acetic acid mvura yemvura painosangana nemvura yakanyorovera, zvichikonzera kuora kwemakemikari.

Nzira yekuziva chaiyo 304 simbi dzesimbi zvigadzirwa?
A. Kutsigira 304 simbi isina simbi yakakosha yekuongorora potion, kana ikasachinja ruvara, ndeye 304 simbi isina chinhu.
B. Kutsigira kwemakemikari ekuongorora uye kuongorora kwespecral.
C. Kutsigira hutsi bvunzo kuteedzera chaiyo nharaunda yekushandisa.

Ndeapi marudzi akasarudzika esimbi isimbi?
A.201 simbi isina simbi, yakakodzera kushandiswa munzvimbo dzakaoma, zviri nyore kuita ngura inosangana nemvura.
B. 304 simbi isina chinhu, yekunze kana nyoro nharaunda, yakasimba ngura uye acid kuramba.
C. 316 simbi isina chinhu, yakawedzera molybdenum, inowedzera ngura, kunyanya inokodzera mvura yegungwa nemakemikari midhiya.
