Corrosion resistant simbi ndeye yakakosha alloy simbi ine yakanakisa corrosion resistance kunyanya nekuwedzera corrosion-resistant alloy design zvinhu zvakaita semhangura, nickel, uye chromium.

Simbi yerudzi urwu inokwanisa kuramba kukukurwa mumidhiya yakasiyana-siyana inoparadza.

Kudzivirirwa kwayo kwekuora kwakapetwa ka 2-8 kupfuura iyo yakajairwa kabhoni simbi. Sezvo nguva yekushandiswa ichiwedzera, iyo corrosion resistance inova yakakurumbira.

Corrosion resistant steel imhando yesimbi inodzivirira kubva mukuora, zvichiita kuti isaite ngura.

ngura isingadziviriri simbi

Stainless simbiisimbi-based alloys ine ishoma ye10.5% chromium, inokwana kudzivirira ngura pasi peyakajairwa mukamuri-tembiricha mamiriro emumhepo.

Kuwedzera kune yakanaka corrosion kuramba, corrosion resistant simbi zvakare ine yakanakisa mechaniki zvivakwa, welding zvivakwa, nezvimwe.

Naizvozvo, inoshandiswa zvakanyanya muindasitiri yepetrochemical, mainjiniya emugungwa, indasitiri yemakemikari, engineering yekudzivirira kwezvakatipoteredza, engineering yemagetsi nemimwe minda kugadzira midziyo yakasiyana-siyana, mapaipi, matangi ekuchengetedza, zvikamu, nezvimwe. midziyo.

Musi waKurume 11, 2024, European Commission yakapa chiziviso ichiti yakanga yaita yekutanga anti-dumping ongororo yekuvira kwezuva mutongo wekupedzisira paCorrosion Resistant Steels inovambira kuChina, ichitonga kuti kana matanho ekurwisa kurasa akabviswa, kuraswa kwezvigadzirwa. zvinosanganisirwa uye kukuvadzwa kwekurasa kwakakonzerwa kumaindasitiri eEU kuchaenderera mberi kana kuitika zvakare, saka zvakasarudzwa kuti zvirambe zvichichengetedza mabasa ekurwisa-kurasa pane zvigadzirwa zveChinese zvinobatanidzwa.

Iwo anti-dumping mutero mitengo ndeye 17.2% kusvika 27.9%.

Nguva yekuferefetwa kwenyaya iyi kubva muna Ndira 1, 2022 kusvika Zvita 31, 2022, uye nguva yekuferefeta yekukuvadza inobva muna Ndira 1, 2019 kusvika pakupera kwenguva yekuferefeta yekurasa.

Musi waZvita 9, 2016, European Commission yakatanga kuferefeta kuraswa kwesimbi inodzivirira simbi kubva kuChina.

Musi wa8 Kukadzi 2018, European Commission yakaita mutongo wekupedzisira wekupokana nekurasira simbi inodzivirira ngura kubva kuChina.

Musi waKukadzi 8, 2023, European Commission yakatanga ongororo yekutanga yekudzivirira kurasa zuva kuferefetwa kwesimbi isingadziviriri kubva kuChina.

Kune akasiyana mamodheru e-corrosion resistant simbi, ayo anonyanya kugadzirwa zvichienderana nenzvimbo dzakasiyana dzekushandisa uye corrosion resistance zvinodiwa.

Heano mamwe akajairika corrosion resistant steel modhi:

304 pndiro yesimbi isina tsvina:Iyi modhi ine yakanaka corrosion kuramba uye kugadzirisa kuita, uye inoshandiswa zvakanyanya mukudya, mushonga, makemikari uye mamwe maindasitiri.

316 ndiro yesimbi isina tsvina:Mo element inowedzerwa pahwaro hwe304 kuvandudza corrosion resistance uye yakanyanya tembiricha kuita, uye inokodzera nharaunda dzinoora dzine tembiricha yakanyanya uye yakanyanya kudzvanywa.

06Cr19Ni10:Iyi iplate ye-austenitic Stainless steel ine zvikamu zvikuru zveCr, Ni, C, nezvimwewo. Iine kunaka kwekusagadzikana kwekugadzirisa uye kushandiswa kwekugadzirisa uye inoshandiswa zvakanyanya mumakemikari indasitiri, petroleum nedzimwe minda.

022Cr17Ni12Mo2:Iyi iplate yesimbi isingadziviriri kukoromoka inoumbwa neCr, Ni, Mo, zvichingodaro. Inodzivirira kupisa kwakanyanya uye inoshandiswa zvakanyanya mupetrochemical, organic chemical, aviation, aerospace nezvimwe minda.

00Cr17Ni14Mo2:Iyi isimbi yakakwirira-yakasimba simbi isina tsvina inoumbwa neCr, Ni, Mo, etc. Iine yakanakisa kusagadzika kwekuora uye kusapfeka kupfeka uye inowanzoshandiswa mukugadzira michina muindasitiri yemakemikari, petroleum nedzimwe minda.
