Simbi isingatsvi 304, iri imwe yemhando dzesimbi isingatsvi simbi dzinoshandiswa zvakanyanya, inoonekwa sechinhu chinoshamisa nekuda kwekusagadzikana kwayo nengura, kusapisa, simba rayo pakupisa kwakaderera, uye hunhu hwayo hwemakanika. Uyezve, inoratidza kushanda zvakanaka pakupisa pasina kuomeswa nekupisa.

Kufanana nesimbi isingatsvi 304, simbi isingatsvi 304L yakasiyana mukugadzirwa kwayo kwemakemikari. Kabhoni yakawanda yesimbi isingatsvi 304 i0.08%, nepo simbi isingatsvi 304L yemhando yepamusoro ine kabhoni yakawanda ye0.03% chete. Musiyano uyu unoratidzwa ne "L" mu304L, zvichireva kabhoni yakaderera zvakanyanya. Inowanzoshandiswa mukugadzira michina nezvikamu zvinoda kusimbaradzwa nekuora uye kugona kuumbwa.

Simbi isingatsvinyike ye316 ine imwe 2-3% molybdenum, pamwe chete nesimbi, chromium, uye nickel. Kuvapo kwemolybdenum kunowedzera kushanda kwesimbi isingatsvinyike ye316 munzvimbo dzine ngura dzine chloride. Nekuda kweizvozvo, isarudzo inofarirwa nevakawanda mumamiriro ezvinhu akadaro.

Simbi isina ngura ye316L, yakafanana nesimbi isina ngura ye316, ine kabhoni shoma isingapfuure 0.03% mukugadzirwa kwayo. Kuderedzwa uku kwakagadzirirwa kuderedza njodzi yekunaya kwekabhoni, zvichiita kuti ive sarudzo iri nani yekunamira kuti irambe yakasimba mukuora.

Simbi isina ngura ye410 isimbi isina ngura inoshandiswa zvakanyanya mukugadzirwa kwesimbi ine simbi, kabhoni, chromium, nezvimwe zvinhu zvishoma.

Simbi isingatsvi 430 yagara ichishandiswa zvakanyanya nekuda kwekugara kwayo kwenguva refu uye kuramba kwayo ngura. Kunyange zvakadaro, simbi isingatsvi 430 inogona kukonzera matambudziko nekuda kwehuwandu hwayo hwe chromium.

Simbi isingatsvedzeri ye904L inozivikanwa nekudzivirira kwayo ngura, kusimba kwayo, uye hunhu hwayo hwemakanika. Nekuda kwekutsungirira kwayo zvakanyanya nharaunda dzakaoma, simbi isingatsvedzeri ye904L inowanzoshandiswa mukugadzira zvinhu zvemaindasitiri akadai sepetroleum, makemikari, uye engineering yegungwa.

Simbi isingatsvinyi 301 isimbi isingatsvinyi simbi inowanzo shandiswa mu austenitic ine 17% chromium uye 7% nickel, inopa simba rakawedzerwa uye kugona kugadzikana kana yashandiswa muchando. Pamusoro pezvo, ine hunhu hwakanaka hwekudzivirira ngura.

Simbi isingasvibi 416 inonyanya kuve nesimbi, chromium, uye nickel. Chiyero chayo chemakemikari chaiwo chinodzivirira ngura uye chinoita kuti michina ive nehunyanzvi hwakanaka.

Bhaa resimbi isina tsvina yemhando ye2507 duplex rakagadzirwa nesimbi isina tsvina yeferritic-austenitic duplex inozivikanwa nekudzivirira kwayo ngura zvakanyanya. Rinopa dziviriro yakakwana kubva pakuora kwenzvimbo, ngura yakatsemuka, uye ngura yakafanana nekuda kwehuwandu hwakanaka hwezvinhu zvechromium nemolybdenum.
