Stainless Steel Overview
Simbi isina ngura: Mhando yesimbi inozivikanwa nekudzivirira kwayo kuparara uye isina-kupisa zvinhu, ine kanenge 10.5% chromium uye yakawanda ye1.2% kabhoni.
Stainless simbi chinhu chinoshandiswa zvakanyanya mumaindasitiri akasiyana siyana, ine mukurumbira nekusaita ngura uye kuita zvakasiyana-siyana. Pakati pemagiredhi mazhinji esimbi isina tsvina, 304, 304H, 304L, uye 316 ndiwo anonyanya kuzivikanwa, sekutsanangurwa kweASTM A240/A240M chiyero che "Chromium neChromium-Nickel Stainless Steel Plate, Sheet, uye Strip for Pressure Vessels uye General. Applications.”
Aya magiredhi mana ndeechikamu chimwe chete chesimbi. Anogona kuverengerwa seaustenitic Stainless simbi zvichienderana nechimiro chadzo uye se300 akatevedzana chromium-nickel Stainless simbi zvichienderana nekuumbwa kwavo. Misiyano yepakutanga pakati payo iri mukuumbwa kwavo kwemakemikari, corrosion resistance, heat resistance, uye nzvimbo dzekushandisa.
Austenitic Stainless Simbi: Inonyanya kuumbwa nechiso-chepakati cubic crystal chimiro (γ chikamu), isiri-magineti, uye inonyanya kusimbiswa kuburikidza nekushanda kunotonhora (izvo zvinogona kukurudzira mamwe magineti). (GB/T 20878)
Kemikari Kuumbwa uye Kuenzanisa Kwekuita (Kubva paASTM Maitiro)
304 Stainless Simbi:
- Main Kuumbwa: Iine inenge 17.5-19.5% chromium uye 8-10.5% nickel, ine kabhoni shoma (pasi pe0.07%).
- Mechanical Properties: Inoratidza yakanaka tensile simba (515 MPa) uye elongation (inenge 40% kana kupfuura).
304L Stainless Simbi:
- Main Kuumbwa: Zvakafanana ne304 asi ine yakaderedzwa kabhoni yemukati (pazasi 0.03%).
- Mechanical Properties: Nekuda kweiyo yakaderera kabhoni yemukati, iyo tensile simba yakadzikira zvishoma pane 304 (485 MPa), ine elongation yakafanana. Iyo yakaderera kabhoni yemukati inosimudzira yayo welding kuita.
304H Stainless Simbi:
- Main Kuumbwa: Carbon content inowanzobva pa0.04% kusvika 0.1%, ine manganese yakaderedzwa (kudzika kusvika 0.8%) uye yakawedzera silicon (kusvika 1.0-2.0%). Chromium uye nickel zvirimo zvakafanana ne304.
- Mechanical Properties: Kusimba kwesimba (515 MPa) uye kureba kwakafanana ne 304. Iine simba rakanaka uye kuoma pakupisa kwepamusoro, zvichiita kuti ive yakakodzera kune nzvimbo dzepamusoro-soro.
316 Stainless Simbi:
- Main Kuumbwa: Iine 16-18% chromium, 10-14% nickel, uye 2-3% molybdenum, ine carbon content iri pasi pe0.08%.
- Mechanical Properties: Kusimba simba (515 MPa) uye kureba (kupfuura 40%). Iine superior corrosion resistance.
Kubva pakuenzanisa kuri pamusoro apa, zviri pachena kuti mamakisi mana ane zvinhu zvakafanana zvemuchina. Misiyano iri mukuumbwa kwavo, izvo zvinotungamira mukusiyana kwekushomeka kwekuora uye kushomeka kwekushisa.
Stainless Steel Corrosion Resistance uye Heat Resistance Kuenzanisa
Corrosion Resistance:
- 316 Stainless Simbi: Nekuda kwekuvapo kwe molybdenum, ine huturu huri nani kupfuura iyo 304 yakatevedzana, kunyanya kurwisa chloride corrosion.
- 304L Stainless Simbi: Iine yakaderera kabhoni yemukati, ine zvakare yakanaka corrosion resistance, yakakodzera nharaunda dzinoparadza. Kudzivirirwa kwayo kwekuora kwakaderera zvishoma kune 316 asi inodhura-inoshanda.
Heat Resistance:
- 316 Stainless Simbi: Yayo yakakwirira chromium-nickel-molybdenum kuumbwa kunopa nani kupisa kupisa kupfuura 304 simbi isina tsvina, kunyanya ne molybdenum inosimudzira ayo oxidation kuramba.
- 304H Stainless Simbi: Nekuda kweiyo yakakwira kabhoni, yakaderera manganese, uye yakakwira silicon kuumbwa, inoratidzawo kunaka kwekupisa kupisa pakupisa kwakanyanya.
Stainless Steel Application Minda
304 Stainless Simbi: Iyo inodhura-inoshanda uye inosiyana-siyana base giredhi, inoshandiswa zvakanyanya mukuvaka, kugadzira, uye kugadzira chikafu.
304L Stainless Simbi: Iyo yakaderera-kabhoni vhezheni ye304, inokodzera makemikari neinjiniya yemugungwa, ine nzira dzekugadzirisa dzakafanana kusvika ku304 asi inokodzera zvirinani kune nharaunda dzinoda kukwirira kwekuora uye kunzwisisika kwemutengo.
304H Stainless Simbi: Inoshandiswa mumagetsi epamusoro uye mareheater emabhailers akakura, pombi dzehutsi, zvinochinjisa kupisa muindasitiri yepetrochemical, uye zvimwe zvikumbiro zvinoda kumira zvakanaka kwekuora uye kuita kwepamusoro-tembiricha.
316 Stainless Simbi: Inowanzoshandiswa mumapuranga uye mapepa emagetsi, indasitiri inorema, kushandiswa kwemakemikari nekuchengetedza zvigadziro, midziyo yekunatsa, mishonga yezvokurapa uye yemishonga, mafuta ekumahombekombe uye gasi, nzvimbo dzegungwa, uye cookware yakakwirira.
