Pakati pemidziyo yesimbi isina tsvina, 304 simbi isina tsvina uye 201 simbi isina tsvina ndiwo maviri akajairika marudzi. Vane mimwe misiyano mukuumbwa kwemakemikari, zvimiro zvemuviri, uye mashandisirwo.

Chekutanga, 304 Stainless simbi isimbi isina tsvina ine corrosion resistance, inosanganisira 18% chromium uye 8% nickel, pamwe nechikamu chidiki chezvinhu zvakaita secarbon, silicon, uye manganese. Ichi chemikemikari chinopa 304 simbi isina tsvina yakanaka corrosion resistance, oxidation resistance, uye high-temperature kuramba. Iyo inewo simba rakakwirira uye ductility, saka inowanzoshandiswa mukugadzirwa kwemidziyo uye zvikamu zvine zvakakwirira zvinodiwa.

201 simbi isina tsvina inoumbwa ne17% kusvika 19% chromium uye 4% kusvika 6% nickel, pamwe chete nekabhoni, manganese, uye nitrogen. Kana ichienzaniswa ne304 Stainless simbi, 201 Stainless simbi ine yakaderera nickel content, saka iyo inodzivirira ngura uye yakanyanya-tembiricha kuramba haina kunaka. Nekudaro, 201 simbi isina simbi ine simba riri nani uye plastiki uye yakakodzera kune yakaderera-inoda zvimiro uye zvekushongedza zvikumbiro.

Panyaya yezvimiro zvemuviri, kuwanda kwe304 simbi isina simbi yakakura, ingangoita 7.93 magiramu/cubic centimita, ukuwo density ye201 Stainless steel ingangoita 7.86 gramu/cubic centimeter. Pamusoro pezvo, 304 simbi isina tsvina ine yakanaka corrosion resistance uye inokwanisa kuramba corrosion kubva mumhepo yakawanda, mvura yakachena, steam, uye chemical media; nepo 201 simbi isina tsvina inogona kukonzera ngura mune dzimwe nzvimbo dzinoparadza.

Panyaya yekushandiswa, 304 simbi isina tsvina inowanzoshandiswa mukugadzira makemikari emidziyo, midziyo yekumanikidza, midziyo yekugadzira chikafu, uye mamwe minda inoda yakakwira corrosion resistance uye yakakwirira-tembiricha kuramba. 201 simbi isina tsvina inowanzoshandiswa mukugadzira midziyo yekubikira, kushongedza kwemba, uye zvimwe zviitiko zvinoda kusimba kwepamusoro uye plastiki asi yakaderera kushomeka kwekudzivirira.

Kazhinji, 304 Stainless simbi ine zvirinani kusaita ngura, yakakwirira-tembiricha kuramba, uye oxidation kuramba kupfuura 201 Stainless simbi, uye inokodzera minda yeindasitiri ine zvinodiwa zvepamusoro. 201 simbi isina tsvina inonyanya kukodzera maapplication ane akakwira simba uye mapurasitiki zvinodiwa asi yakaderera corrosion kuramba zvinodiwa. Pakusarudza simbi isina tsvina, kusarudzwa kunofanirwa kuve kwakavakirwa pane chaiyo kushandiswa nharaunda uye zvinodiwa.
