Cov ntsiab lus tseem ceeb hais txog kev tiv thaiv corrosion ntawm St60-2 cov qauv hlau phaj feem ntau muaj feem xyuam rau cov ntsiab lus alloying, microstructure, thiab kev pabcuam ib puag ncig, raws li cov lus qhia hauv qab no:

Lub luag haujlwm ntawm Alloying Elements

St60-2 structural steel daim hlau muaj alloying ntsiab xws li chromium (Cr) thiab npib tsib xee (Ni), uas pab txhim kho corrosion kuj ntawm cov hlau. Chromium can form a dense oxide film on the surface of the steel, preventing corrosive media such as oxygen and moisture from contacting the steel matrix, thereby slowing down the corrosion rate. Qhov sib ntxiv ntawm npib tsib xee tuaj yeem txhim kho lub peev xwm passivation ntawm cov hlau, txhim kho nws cov corrosion kuj nyob rau hauv ntau qhov chaw, tshwj xeeb tshaj yog rau qee cov oxidizing acids thiab ntsev daws. Tsis tas li ntawd, qhov tsim nyog ntawm silicon (Si) thiab manganese (Mn) tuaj yeem kho cov nplej, txhim kho lub zog thiab hardness ntawm cov hlau, thiab tsis muaj kev cuam tshuam zoo rau corrosion kuj. Manganese kuj tseem tuaj yeem tsim manganese sulfide nrog sulfur, txo qhov cuam tshuam tsis zoo ntawm cov sulfur ntawm corrosion kuj ntawm cov hlau.

Kev cuam tshuam ntawm Impurity Elements

Phosphorus (P) thiab sulfur (S) yog cov teeb meem impurity hauv cov hlau uas tuaj yeem txo qhov corrosion ntawm cov hlau. Phosphorus tuaj yeem ua rau txias brittleness hauv steel, thiab sulfur tuaj yeem ua rau kub brittleness. Ob leeg yuav ua puas lub microstructure ntawm cov hlau thiab ua rau kom cov rhiab heev ntawm cov hlau nyob rau hauv corrosive ib puag ncig. Yog li ntawd, St60-2 structural steel daim hlau muaj kev txwv nruj ntawm phosphorus thiab sulfur cov ntsiab lus, feem ntau xav tau cov ntsiab lus phosphorus tsawg dua lossis sib npaug li 0.05% thiab cov ntsiab lus sulfur tsawg dua lossis sib npaug li 0.05%.

 

 

 

 

 

Kev cuam tshuam ntawm Microstructure

Cov qauv zoo ib yam thiab zoo lis pab txhim kho corrosion kuj ntawm cov hlau. Los ntawm cov txheej txheem dov thiab kev kho cua sov kom tsim nyog, St60-2 cov qauv steel daim hlau tuaj yeem tau txais cov qauv zoo li qub thiab zoo, txo cov qoob loo ciam teb tsis xws luag thiab muaj peev xwm ntawm corrosive media nkag mus raws li cov ciam teb, yog li txhim kho corrosion kuj.
