Chii chinonzi Steel?
Simbi ndeye alloy yeIron uye chikuru (chikuru) chinosanganisa chinhu iCarbon. Nekudaro, pane zvimwe zvinosiya kune iyi tsananguro senge interstitial-isina (IF) masimbi uye mhando 409 ferritic Stainless simbi, umo kabhoni inoonekwa setsvina.
Chii chinonzi Alloy?
Kana zvinhu zvakasiyana zvasanganiswa muzvikamu zvidiki muchikamu chepasi, chinobuda chinodaidzwa kunzi alloy ye base element. Saka simbi ialloy yeIron nekuti Iron ndiyo base element (main constituent) musimbi uye chinhu chikuru chinosanganisa iCarbon. Zvimwe zvimwe zvinhu zvakaita seManganese, Silicon, nickel, Chromium, Molybdenum, Vanadium, Titanium, Niobium, Aluminium, nezvimwewo zvinowedzerwawo muhuwandu hwakasiyana kugadzira mamakisi (kana marudzi) eSimbi.
Jindalai (Shandong) Steel Group Co., Ltd. inyanzvi uye inotungamira mutengesi wesimbi nesimbi isina simbi mbariro/pombi/makoiri/maplate. Tumira kubvunza kwako uye isu tichafara kukubvunza iwe nehunyanzvi.
Ndedzipi Mhando Dzakasiyana dzeSimbi?
Zvichienderana nemakemikari ekuumbwa, Simbi inogona kuiswa muzvikamu zvina (04) zvemhando:
● Carbon Steel
● Simbi Isina Stainless
● Alloy Steel
● Chishandiso Simbi
1. Carbon Steel:
Carbon simbi ndiyo inonyanya kushandiswa simbi mumaindasitiri uye inodarika 90% yehuwandu hwekugadzirwa kwesimbi. Zvichienderana nekabhoni yemukati, Carbon simbi inoiswazve mumapoka matatu.
● Simbi yeKabhoni Yakaderera/Simbi Yakapfava
● Simbi yeKabhoni Yepakati
● High Carbon steel
Carbon zvirimo zvinopihwa mutafura iri pazasi:
| Aihwa. | Mhando ye carbon steel | Chikamu cheCarbon |
| 1 | Yakaderera Carbon Steel/Simbi yakapfava | Kusvika ku0.25% |
| 2 | Yepakati Carbon Steel | 0.25% kusvika 0.60% |
| 3 | High Carbon simbi | 0.60% kusvika 1.5% |
2. Stainless Simbi:
Simbi isina tsvina isimbi ine alloy ine 10.5% Chromium (Minimum). Simbi isina tsvina inoratidzira corrosion resistance properties, nekuda kwekugadzirwa kweiyo nhete yeCr2O3 pamusoro payo. Mutsara uyu unozivikanwawo sekuti passive layer. Kuwedzera huwandu hweChromium kuchawedzera kuwedzera kusimba kwekupokana kwezvinhu. Pamusoro peChromium, nickel neMolybdenum zvinowedzerwawo kupa zvinodiwa (kana kuvandudzwa) zvivakwa. Simbi isina tsvina inewo huwandu hwakasiyana hweCarbon, Silicon, uye Manganese.
Masimbi asina tsvina anotsanangurwa zvakare se;
1. Ferritic Stainless Steels
2. Martensitic Stainless Steels
3. Austenitic Stainless Steels
4. Duplex Stainless Steels
5. Precipitation-Hardening (PH) Stainless Simbi
● Ferritic Stainless Steel: Ferritic steels inosanganisira Iron-Chromium alloys ine body-centered cubic crystal structures (BCC). Izvi zvinowanzoita magineti uye hazvigone kuomeswa nekurapa kwekupisa asi zvinogona kusimbiswa nekushanda kunotonhora.
● Austenitic Stainless Steel: Masimbi eAustenitic anonyanya kushingirira pakuora. Iyo isiri-magnetic uye isingapise-inorapwa. Kazhinji, austenitic simbi dzinogoneka zvakanyanya.
● Martensitic Stainless Simbi: Martensitic Stainless steels akasimba zvakanyanya uye akaomarara asi asingapindi mukuora semamwe makirasi maviri. Masimbi aya anogoneka zvakanyanya, magineti, uye anorapa kupisa.
● Duplex Stainless Steels: Duplex simbi isina tsvina inosanganisira maviri-phase microstructure inosanganisira zviyo zveferritic uye austenitic stainless steel (kureva Ferrite + Austenite). Duplex simbi dzinenge dzakasimba zvakapetwa kaviri seaustenitic kana ferritic Stainless simbi.
● Precipitation-Hardening (PH) Stainless Steels: Precipitation-Hardening (PH) Stainless Steels vane Ultra high simba nekuda kwekuoma kwemvura.
3. Alloy Steel
Mune alloy simbi, zvakasiyana-siyana zvikamu zvealloying zvinhu zvinoshandiswa, kuti zvibudirire zvinodiwa (zvakavandudzwa) zvinhu zvakadai seweldability, ductility, machinability, simba, kuoma uye kusagadzikana kwemarara, nezvimwewo.
● Manganese - Inowedzera simba uye kuoma, inoderedza ductility uye weldability.
● Silicon - Inoshandiswa se deoxidizers inoshandiswa mukugadzira simbi.
● Phosphorus - Inowedzera simba nekuoma uye inoderedza ductility uye notch kukanganisa kuoma kwesimbi.
● Sulfur -Inoderedza ductility, notch kukanganisa kuoma, uye weldability. Inowanikwa mumhando ye sulfide inclusions.
● Mhangura - yakagadziridzwa kusagadzikana kwekuora.
● Nickel - Inowedzera kuoma uye Impact kusimba kwesimbi.
● Molybdenum - Inowedzera kuoma uye inosimudzira kurwisana kwezvinokambaira zvesimbi dzakadzika-alloy.
4. Tool Steel
Zvishandiso zvesimbi zvine yakakwira kabhoni yemukati (0.5% kusvika 1.5%). Yakakwira kabhoni yemukati inopa yakanyanya kuoma uye simba. Masimbi aya anonyanya kushandiswa kugadzira midziyo uye anofa. Chishandiso chesimbi chine huwandu hwakasiyana hwetungsten, cobalt, molybdenum, uye vanadium kuwedzera kupisa nekupfeka kuramba, uye kusimba kwesimbi. Izvi zvinoita kuti simbi dzematurusi dzive dzakanakira kushandiswa sekucheka nekuchera maturusi.
Jindalai Steel Group inogara yakazara-yakazara neakanakisa hesiti yezvigadzirwa zvesimbi muindasitiri. Jindalai inogona kukubatsira kusarudza akakodzera simbi zvinhu kuti uve nechokwadi chekuti unowana zvaunoda nekukurumidza sezvinobvira kana yave nguva yekutenga. Kana kutenga zvinhu zvesimbi kuri mune ramangwana rako riri pedyo, kumbira quote. Isu tinokupa iyo inokuwanira iwe chaizvo zvigadzirwa zvaunoda nekukurumidza.
