3Cr12 vs. 410S Stainless Hlau Phaj: Daim Ntawv Qhia rau Kev Xaiv thiab Kev Sib Piv

Thaum xaiv cov khoom siv hlau tsis muaj steel, 3Cr12 thiab 410S yog ob txoj kev siv ntau. Thaum ob qho tib si yog cov hlau tsis muaj steel, lawv muaj qhov sib txawv tseem ceeb hauv cov tshuaj lom neeg muaj pes tsawg leeg, kev ua tau zoo, thiab cov chaw siv. Kab lus no yuav qhia txog qhov sib txawv tseem ceeb ntawm ob daim hlau stainless thiab lawv daim ntawv thov, pab koj txiav txim siab xaiv rau koj cov haujlwm.

3Cr12 stainless hlau yog dab tsi?

3Cr12 stainless hlau ntawvyog ferritic stainless hlau muaj 12% Cr, uas yog sib npaug rau qib European 1.4003. Nws yog kev lag luam ferritic stainless hlau siv los hloov coated carbon steel, weathering steel thiab txhuas. Nws muaj cov yam ntxwv ntawm kev ua haujlwm yooj yim thiab kev tsim khoom, thiab tuaj yeem welded los ntawm cov pa vuam tshuab. Nws tuaj yeem siv los ua: lub cev muaj zog, chassis, hoppers, conveyor siv, mesh screens, conveying troughs, thee bins, containers and tanks, chimneys, air ducts, and outer coverers, Panels, sidewalks, stairs, rails, etc.

Dab tsi yog 410S stainless hlau?

https://www.sakysteel.com/410-stainless-steel-sheet.html

410S stainless hlauyog ib qho uas tsis muaj cov pa roj carbon monoxide, uas tsis yog-hardening hloov kho ntawm martensitic stainless hlau 410. Nws muaj li ntawm 11.5-13.5% chromium thiab me me ntawm lwm cov ntsiab lus xws li manganese, phosphorus, sulfur, silicon, thiab qee zaum nickel. Cov ntsiab lus qis dua ntawm 410S txhim kho nws txoj kev weldability thiab txo qhov kev pheej hmoo ntawm hardening los yog tawg thaum vuam. Txawm li cas los xij, qhov no kuj txhais tau hais tias 410S muaj lub zog qis dua piv rau tus qauv 410.Muaj zoo corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig me me, tab sis tsis tshua muaj resistant dua austenitic stainless hlau zoo li 304 lossis 316.

Ⅱ.3Cr12 thiab 410S Steel Phaj Properties

3Cr12 Stainless hlau: Exhibits zoo toughness thiab weldability, haum rau ntau yam txheej txheem.Muab lub zog me me thiab hnav tsis kam, ua rau nws muaj peev xwm tiv taus qee yam kev ntxhov siab.
410S Stainless hlau:Features siab dua hardness, ua rau nws haum rau high-temperature daim ntaub ntawv, tab sis muaj tsis zoo weldability.Nws lub zog thiab kub kuj ua rau nws excel nyob rau hauv high-temperature tej yam kev mob.

3 cr12 460 220 18%
3 cr12l 455 223 20%
410 S 415 183 20%

Ⅲ.3Cr12 thiab 410S Steel Phaj Daim Ntawv Thov Cheeb Tsam

3 cr12: Siv dav hauv cov khoom siv tshuaj, khoom noj khoom haus, thiab cov ntaub ntawv tsim kho.Nws zoo corrosion kuj ua rau nws zoo tagnrho rau cov av noo thiab acidic ib puag ncig.
410 S: Feem ntau siv nyob rau hauv turbine Cheebtsam, boilers, thiab tshav kub exchangers nyob rau hauv high-temperature ib puag ncig.Suitable rau daim ntaub ntawv uas yuav tsum tau tshav kub thiab hnav tsis kam.

Ⅳ.Cov ntsiab lus sib piv

Cov yam ntxwv tseem ceeb ntawm 3Cr12:
• Muaj pes tsawg leeg: Chromium cov ntsiab lus ntawm 11.0–12.0%, cov ntsiab lus carbon ≤ 0.03%.
• Corrosion Resistance: Haum rau me me corrosive ib puag ncig, xws li cov khoom siv, cov khoom siv mining, thiab kev siv dav hauv kev lag luam.
• Weldability: Kev vuam zoo vim nws cov ntsiab lus carbon tsawg.

Txuj Qib
South African Standard 3 cr12
European Standard 1.400 3
US Standard UNS S41003 (410S)
International Standard X2CrNi12

• 410 S: Siab hardness tab sis me ntsis qis toughness, tsis muaj titanium, muaj nruab nrab weldability, thiab yog haum rau dav siv corrosion-resistant daim ntaub ntawv.
• 3Cr12: Tsawg carbon, nqi-zoo, haum rau me me corrosive ib puag ncig, nrog zoo weldability.
