S355j2 Tsawg Alloy Steel Phaj: Tus Txheej Txheem

S355J2 yog qhov siv tau siv qis qis- Alloy} almin cov qauv hlau ua kom muaj zog, kev ua tiav zoo, thiab weldability, thiab weldability. Nws zwm rau tus qauv EN 10025 Cov Qauv (European qauv) thiab feem ntau tau teev nyob rau hauv kev tsim kho, engineering, thiab hnyav tshuab cov ntawv thov. Hauv qab no yog cov ncauj lus kom ntxaws tawg ntawm nws cov yam ntxwv tseem ceeb, cov yam ntxwv, thiab cov ntawv thov:

 

 

 

Cov Khoom Siv Neeg Kho Tshuab

S355J2 tau cais raws li "siab -}}}}}}}}}}}}}}}}}}}}}}} Cov khoom siv rau cov qauv txheej txheem:

 

Paib lub zog: Ntau dua lossis sib npaug zos rau 355 MPa (ntawm thickness tsawg dua los yog sib npaug nrog kev nce qib siab, thiab ntau dua lossis sib npaug rau 16-40 hli).

Lub zog tensile: 470-630 MPa.

Elongation: Ntau dua los yog sib npaug rau 22% (rau thickness tsawg dua los yog sib npaug rau 16 hli), ua kom muaj zog rau kev sib sau.

Kev Cuam Tshuam: Ntau dua lossis sib luag rau 27 j ntawm-} l {motion v {} Tsis muaj kev phom sij qis.

Kev nyuaj: Feem ntau 130-180 hb (brinell), ntsuas lub zog thiab machinibilability.

 

 

 

 

 

 

Tswj Tuav Lub Sij Hawm: Homogenization ntawm Austenite

Thaum cov hlau mus txog qhov kubtenerical kub, nws yog muaj nyob rau qhov kub ntawd rau qee yam tshwj xeeb (feem ntau 1 hli ntawm thickness).

 

Lub ntsiab lus: Cov sijhawm no tso cai rau cov khoom siv ua haujlwm (piv txwv li, mn, si) kom diffuse tusyees tsis pub dhau ntawm Austenite Matrix, txo cov tshuaj inomogeneity. Nws kuj tseem ua kom tau txhua lub microstration puv (piv txwv li, carbides ua kom tiav rau hauv Austenite mus rau hauv Austenite, tso lub hauv paus rau ib pawg microstration microstration moture.

 

 

Cua Txias: Tswj Hloov Kho Kom Zoo Nkauj Microstructure

Tom qab tuav, cov hlau yogtxias rau hauv tseem lossis yuam cua(raws li txwv kom qeeb cua sov hauv annealing). Qhov no tswj kom txias txias yog cov cai txhais tau tias sib txawv ntawm anealing.

 

Microstructure: Raws li cov paustenite txias hauv qab AC3, nws hloov rov qab rau hauvferrite(theem thawj) thiablub hlaws, tab sis nrog cov khoom plig tseem ceeb:

Ferrite nplej: Huab cua txias txhawb nqa nrawm dua nucleation ntawm ferrite, ua rau me, muaj ntau ererrite nplej (piv rau coarser nplej hauv qeeb txias).

Lub hlaws: Tus nqi ua kom nrawm dua yuav ua rau cov qauv pearlite, ua kom lamellar (fawm kib (fished) hlaws thiab ntau dua cov faib khoom dua.
