Posankha zitsulo zosapanga dzimbiri, 3Cr12 ndi 410S ndi njira ziwiri zomwe zimagwiritsidwa ntchito kwambiri. Ngakhale kuti zonsezi ndi zitsulo zosapanga dzimbiri, zimasonyeza kusiyana kwakukulu kwa mankhwala, machitidwe, ndi malo ogwiritsira ntchito. Nkhaniyi ifotokoza za kusiyana kwakukulu pakati pa mbale ziwiri zachitsulo zosapanga dzimbiri ndi kagwiritsidwe ntchito kake, kukuthandizani kupanga zisankho mozindikira pamapulojekiti anu.
Kodi 3Cr12 chitsulo chosapanga dzimbiri ndi chiyani?
3Cr12 chitsulo chosapanga dzimbiri pepalandi chitsulo chosapanga dzimbiri cha ferritic chokhala ndi 12% Cr, chomwe ndi chofanana ndi kalasi ya European 1.4003. Ndi chitsulo chosapanga dzimbiri cha ferritic chomwe chimagwiritsidwa ntchito m'malo mwa chitsulo chophimbidwa ndi kaboni, chitsulo chosapanga dzimbiri ndi aluminiyamu. Iwo ali ndi makhalidwe osavuta processing ndi kupanga, ndipo akhoza welded ndi luso ochiritsira kuwotcherera. Itha kugwiritsidwa ntchito kupanga: mafelemu agalimoto, chassis, hoppers, malamba otumizira, zowonetsera mauna, zotengera, nkhokwe zamakala, zotengera ndi akasinja, chimneys, ma ducts a mpweya, ndi zophimba zakunja, mapanelo, misewu, masitepe, njanji, etc.
410S chitsulo chosapanga dzimbiri ndi chiyani?
410S chitsulo chosapanga dzimbirindi otsika mpweya, sanali kuumitsa kusinthidwa martensitic zosapanga dzimbiri zitsulo 410. Lili pafupifupi 11.5-13.5% chromium ndi zochepa zinthu zina monga manganese, phosphorous, sulfure, silicon, ndipo nthawi zina faifi tambala. Mpweya wochepa wa carbon 410S umapangitsa kuti kutentha kwake kuwonongeke komanso kumachepetsa chiopsezo choumitsa kapena kusweka panthawi yowotcherera. Komabe, izi zikutanthawuzanso kuti 410S ili ndi mphamvu zochepa poyerekeza ndi 410. Imapereka kukana kwa dzimbiri kwabwino, makamaka m'madera ocheperako, koma imakhala yochepa kwambiri kuposa zitsulo zosapanga dzimbiri za austenitic monga 304 kapena 316.

Ⅱ.3Cr12 ndi 410S Steel Plate Properties
3Cr12 Chitsulo chosapanga dzimbiri: Imawonetsa kulimba kwabwino komanso kuwotcherera, koyenera njira zosiyanasiyana zopangira.Imapereka mphamvu zolimbitsa thupi komanso kukana kuvala, ndikupangitsa kuti ikhale yolimbana ndi zovuta zina zamakina.
410S Chitsulo chosapanga dzimbiri:Imakhala ndi kuuma kwapamwamba, kumapangitsa kuti ikhale yoyenera kugwiritsira ntchito kutentha kwakukulu, koma imakhala ndi weldability wosauka.Mphamvu yake ndi kukana kutentha kumapangitsa kuti ikhale yopambana kwambiri pakutentha kwambiri.
| Gulu | Rm (MPa) | Kulimba Kwambiri (BHN) | Elongation |
| 3Kr12 | 460 | 220 | 18% |
| 3Cr12L | 455 | 223 | 20% |
| 410s | 415 | 183 | 20% |
Ⅲ.3Cr12 ndi 410S Steel Plate Application Area
3Kr12: Amagwiritsidwa ntchito kwambiri pazida zamakina, zida zopangira chakudya, ndi zida zomangira.Kukana kwake kwa dzimbiri kumapangitsa kukhala koyenera kumadera a chinyezi ndi acidic.
410s:Kawirikawiri amagwiritsidwa ntchito mu turbine zigawo zikuluzikulu, boilers, ndi exchangers kutentha m'malo otentha kwambiri.Zoyenera ntchito zomwe zimafuna kutentha ndi kuvala kukana.
Ⅳ.Chidule cha Kufananiza
Zofunikira zazikulu za 3Cr12:
• Kupanga: Zomwe zili mu Chromium za 11.0-12.0%, za carbon ≤ 0.03%.
• Kulimbana ndi Corrosion Resistance: Ndikoyenera kumadera osawononga pang'ono, monga zida zomangira, zida zamigodi, ndi ntchito zama mafakitale.
• Weldability: Kuchita bwino kwa kuwotcherera chifukwa cha kuchepa kwa carbon.
| Standard | Gulu |
| South Africa Standard | 3Kr12 |
| European Standard | 1.4003 |
| US Standard | UNS S41003 (410S) |
| International Standard | X2CrNi12 |
• 410S: Kulimba kwapamwamba koma kutsika pang'ono kulimba, kulibe titaniyamu, kuli ndi mphamvu zowotcherera pang'ono, ndipo ndi yoyenera kugwiritsira ntchito zowonongeka zowonongeka.
• 3Cr12: Mpweya wochepa, wotchipa, woyenera malo owononga pang'ono, okhala ndi weldability wabwino.
