Maitiro ekugadzira banga resimbi isina ngura, forogo nechipunu chidiki chekudya kwemanheru anoitwa nemaitiro akawanda akaomarara akadai sekugadzika, kukwesha uye kukuya.
Zvishongo zvemumba zvesimbi isingatsvi zvinogona kukamurwa kuita 201, 430, 304 (18-8) uye 18-10.
430 simbi isina ngura:
Iron + chromium inopfuura 12% inogona kudzivirira oxidation inokonzerwa nezvinhu zvechisikigo. Inonzi simbi isingatsvi. MuJIS, inonzi code 430, saka inonziwo 430 simbi isingatsvi. Zvisinei, 430 simbi isingatsvi haigone kuramba oxidation inokonzerwa nemakemikari ari mumhepo. 430 simbi isingatsvi haiwanzo shandiswa kwenguva yakati, asi icharamba ichipiswa (yakaora) nekuda kwezvinhu zvisiri zvechisikigo.
18-8 simbi isina ngura:
Iron + 18% chromium + 8% nickel inogona kuramba kuoxidation yemakemikari. Iyi simbi isingasvibiswi inhamba 304 muJIS code, saka inonziwo 304 simbi isingasvibiswi.
18-10 simbi isina ngura:
Zvisinei, kune zvinhu zvakawanda zvemakemikari mumhepo, uye kunyange 304 ichaita ngura munzvimbo dzakasvibiswa zvakanyanya; Saka, zvimwe zvigadzirwa zvepamusoro-soro zvinogadzirwa ne10% nickel kuti zvigare kwenguva refu uye zvisaora. Rudzi urwu rwesimbi isingatsvi inonzi 18-10 stainless steel. Mune mimwe mirairo yemidziyo yekudyara, pane chirevo chakafanana ne "kushandisa 18-10 most advanced medical stainless steel".
Zvichienderana nekuongorora kwedata research centre, simbi isina ngura inogona kukamurwa kuita zvikamu zvitatu: austenitic stainless steel, ferritic stainless steel uye martensitic stainless steel. Zvikamu zvikuru zvesimbi isina ngura isimbi, chromium uye nickel alloys. Pamusoro pezvo, inewo zvinhu zvidiki zvakaita semanganese, titanium, cobalt, molybdenum uye cadmium, izvo zvinoita kuti kushanda kwesimbi isina ngura kugadzikane uye ine ngura uye inodzivirira ngura. Austenitic stainless steel haisi nyore kuisirwa magineti nekuda kwehunhu hwemukati hwemamorekuru.
