Carbon Steel
Simbi ine zvimiro zvemichina inotsamira zvakanyanya pane kabhoni yesimbi uye iyo isina yakakosha alloying zvinhu zvinowanzowedzerwa, dzimwe nguva inonzi plain kabhoni kana kabhoni simbi.
Carbon steel, inonziwo kabhoni simbi, inoreva iron-carbon alloys ine isingasviki 2% carbon WC.
Carbon simbi inowanzo ine zvidiki zvesilicon, manganese, sarufa uye phosphorus kuwedzera kabhoni.
Maererano nekushandiswa kwekabhoni simbi inogona kugoverwa muzvikamu zvitatu zvekabhoni structural simbi, kabhoni mudziyo simbi uye vakasununguka kutema structural simbi, kabhoni structural simbi inokamurwa kuva maviri marudzi structural simbi pakuvaka uye muchina kuvaka;
Zvinoenderana neyakanyungudutswa nzira inogona kukamurwa kuita flat choto simbi, converter simbi uye magetsi choto simbi;
Zvinoenderana neiyo deoxidation nzira inogona kukamurwa kuita simbi inopisa (F), sedentary simbi (Z), semi-sedentary simbi (b) uye yakakosha sedentary simbi (TZ);
Zvinoenderana nekabhoni yemukati kabhoni simbi inogona kukamurwa kuita yakaderera kabhoni simbi (WC ≤ 0.25%), yepakati kabhoni simbi (WC0.25% -0.6%) uye yakakwirira kabhoni simbi (WC> 0.6%);
Zvinoenderana nefosforasi, sarufa yemukati kabhoni simbi inogona kukamurwa kuita yakajairwa kabhoni simbi (ine phosphorus, sarufa yakakwirira), yepamusoro kabhoni simbi (ine phosphorus, sarufa yakaderera) uye yemhando yepamusoro simbi (ine phosphorus, sarufa yakaderera) uye simbi yakakosha yemhando yepamusoro.
Iyo yakakwirira iyo kabhoni yemukati mune yakawanda kabhoni simbi, iyo yakakura kuoma, inowedzera simba, asi yakaderera iyo plastiki.
Simbi isina ngura
Stainless acid-resistant steel inonzi simbi isina tsvina, iyo inoumbwa nezvikamu zviviri zvikuru: Stainless steel uye acid-resistant simbi.Muchidimbu, simbi inokwanisa kurwisa ngura yemuchadenga inonzi simbi isina tsvina, ukuwo simbi inokwanisa kuramba kuita ngura nemakemikari media inodaidzwa kuti acid-resistant steel.Simbi isina simbi isimbi yakakwira-alloy ine inopfuura 60% yesimbi sematrix, ichiwedzera chromium, nickel, molybdenum uye zvimwe zvinosanganiswa zvinhu.
Kana simbi ine zvinopfuura 12% chromium, simbi mumhepo uye dilute nitric asidhi haisi nyore corrode uye ngura.Chikonzero ndechekuti chromium inogona kuumba chidimbu chakasimba che chromium oxide firimu pamusoro pesimbi, ichidzivirira zvinobudirira simbi kubva mukuora.Simbi isina tsvina mune chromium yemukati inowanzopfuura 14%, asi Stainless simbi haina ngura zvachose.Munharaunda dzemahombekombe kana kumwe kusvibiswa kwemhepo kwakakomba, kana mhepo yechloride ion yemukati yakakura, pamusoro pesimbi isina tsvina yakavhurika mumhepo inogona kunge iine dzimwe ngura, asi idzi ngura dzinongogumira pamusoro, hazvizokorodze simbi isina tsvina. mukati matrix.
Kazhinji kutaura, huwandu hwe chrome Wcr yakakura kupfuura 12% yesimbi ine hunhu hwesimbi isina tsvina, simbi isina tsvina zvichienderana neiyo microstructure mushure mekupisa kurapwa inogona kukamurwa muzvikamu zvishanu: zvinoti, ferrite Stainless simbi, martensitic Stainless simbi, austenitic Stainless. simbi, austenitic - ferrite Stainless simbi uye precipitated carbonized Stainless simbi.
Simbi isina tsvina inowanzoparadzaniswa nesangano rematrix:
1, ferritic simbi isina tsvina.Iine 12% kusvika 30% chromium.Kupokana kwayo necorrosion, kusimba uye weldability nekuwedzera kwechromium zvirimo uye kunatsiridza chloride stress corrosion resistance iri nani pane mamwe marudzi esimbi isina tsvina.
2, austenitic simbi isina tsvina.Iine inodarika 18% chromium, inewo inosvika 8% nickel uye shoma shoma ye molybdenum, titanium, nitrogen nezvimwe zvinhu.Comprehensive performance yakanaka, inogona kushingirira kune dzakasiyana siyana dze media corrosion.
3, Austenitic - ferritic duplex simbi isina tsvina.Zvese zviri zviviri austenitic uye ferritic simbi isina tsvina, uye ine zvakanakira superplasticity.
4, martensitic simbi isina tsvina.High simba, asi murombo plasticity uye weldability.
