Lapho ukhetha izinto zensimbi engagqwali, i-3Cr12 ne-410S yizinketho ezimbili ezivame ukusetshenziswa. Nakuba zombili ziyizinsimbi ezingenasici, zibonisa umehluko omkhulu ekwakhekeni kwamakhemikhali, ukusebenza, nezindawo zokusetshenziswa. Lesi sihloko sizocubungula umehluko oyinhloko phakathi kwalawa mapuleti amabili ensimbi engagqwali kanye nezicelo zawo ngokulandelana kwazo, sikusize wenze izinqumo ezinolwazi zamaphrojekthi akho.
Iyini i-3Cr12 insimbi engagqwali?
3Cr12 ishidi lensimbi engagqwaliiyinsimbi engagqwali ye-ferritic equkethe u-12% Cr, okulingana nebanga le-European 1.4003. Kuyinsimbi engabizi ye-ferritic eyongayo esetshenziselwa ukufaka esikhundleni se-carbon steel coated, i-weathering steel ne-aluminium. Inezici zokucubungula nokukhiqiza okulula, futhi ingafakwa nge-welding ubuchwepheshe obuvamile. Ingasetshenziselwa ukwenza: amafreyimu ezimoto, ama-chassis, ama-hopper, amabhande okuthutha, izikrini ezinezikhala, imigqomo yokuthutha, imigqomo yamalahle, izitsha namathangi, oshimula, imigudu yomoya, namakhava angaphandle , Amaphaneli, imigwaqo yaseceleni, izitebhisi, ojantshi, njll.
Iyini i-410S insimbi engagqwali?
410S insimbi engagqwaliiyikhabhoni ephansi, ukuguqulwa okungaqini kwe-martensitic insimbi engagqwali 410. Iqukethe cishe u-11.5-13.5% we-chromium kanye namanani amancane wezinye izakhi ezifana ne-manganese, i-phosphorus, isulfure, i-silicon, futhi ngezinye izikhathi i-nickel. Okuqukethwe kwekhabhoni ephansi kwe-410S kuthuthukisa ukushisela kwayo futhi kunciphisa ubungozi bokuqina noma ukuqhekeka ngesikhathi sokushisela. Nokho, lokhu kuphinde kusho ukuthi i-410S inamandla aphansi uma iqhathaniswa ne-410 ejwayelekile.Inikeza ukumelana nokugqwala okuhle, ikakhulukazi ezindaweni ezithambile, kodwa imelana kancane kunezinsimbi ezingenasici ze-austenitic ezifana no-304 noma 316.
Ⅰ.3Cr12 kanye ne-410S Steel Plate Chemical Composition
Ngokusho kwe-ASTM A240.
| Ibanga | Ni | C | Mn | P | S | Si | Cr |
| 3Cr12 | 0.3-1.0 | 0.03 | 2.0 | 0.04 | 0.030 | 1.0 | 10.5-12.5 |
| 3Cr12L | 0.3-1.0 | 0.03 | 1.5 | 0.04 | 0.015 | 1.0 | 10.5-12.5 |
| 410S | 0.75 | 0.15 | 1.0 | 0.04 | 0.015 | 1.0 | 11.5-13.5 |
Ⅱ.3Cr12 kanye ne-410S Steel Plate Properties
3Cr12 Insimbi Engagqwali:Ibonisa ukuqina okuhle nokushisela, ilungele izindlela ezihlukahlukene zokucubungula.Inikeza amandla amaphakathi nokumelana nokugqoka, okuyenza ikwazi ukumelana nezingcindezi ezithile zemishini.
I-410S Stainless Steel:Ifaka ubulukhuni obuphakeme, okuyenza ifanelekele izinhlelo zokusebenza ezishisa kakhulu, kodwa inokushisela okumpofu.Amandla ayo nokumelana nokushisa kuyenza iphumelele ezimweni zokushisa okuphezulu.
| Ibanga | I-Rm(MPa) | Ukuqina Okukhulu(BHN) | Ukwelula |
| 3Cr12 | 460 | 220 | 18% |
| 3Cr12L | 455 | 223 | 20% |
| 410S | 415 | 183 | 20% |
Ⅲ.3Cr12 kanye ne-410S Steel Plate Izindawo Zokufaka Isicelo
3Cr12:Isetshenziswa kakhulu ezintweni zamakhemikhali, izinto zokucubungula ukudla, kanye nezinto zokwakha.Ukumelana nokugqwala kwayo okuhle kuyenza ilungele izindawo ezinomswakama ne-acidic.
410S:Ivame ukusetshenziswa ezingxenyeni zama-turbine, ama-boilers, nezishintshisi zokushisa endaweni enezinga lokushisa eliphezulu.Ifanele izinhlelo zokusebenza ezidinga ukumelana nokushisa nokuguga.
Ⅳ.Isifinyezo sokuqhathanisa
Izici ezibalulekile ze-3Cr12:
• Ukwakhiwa: Okuqukethwe kwe-Chromium okungu-11.0–12.0%, okuqukethwe kwekhabhoni ≤ 0.03%.
• I-Corrosion Resistance: Ifanele indawo enokugqwala kancane, njengezingxenye zesakhiwo, okokusebenza kwezimayini, kanye nezicelo ezijwayelekile zezimboni.
• Ukushisela: Ukusebenza kahle kokushisela ngenxa yokuqukethwe kwayo kwekhabhoni ephansi.
| Okujwayelekile | Ibanga |
| Izinga laseNingizimu Afrika | 3Cr12 |
| I-European Standard | 1.4003 |
| I-US Standard | I-UNS S41003 (410S) |
| I-International Standard | I-X2CrNi12 |
• 410S: Ukuqina okuphakeme kodwa ukuqina okuphansi kancane, ayinayo i-titanium, inokushisela okusesilinganisweni, futhi ifanele izinhlelo zokusebenza ezijwayelekile ezimelana nokugqwala.
• 3Cr12: Ikhabhoni ephansi, eyongayo, ilungele izindawo ezigqwala kancane, ezinokushisela okuhle.
