Mechanical Properties nyob rau hauv nthuav dav

Yield Strength thiab Tensile Strength

Yield zog: Raws li tau hais ua ntej, lub zog tawm los ntawm cov hlau tsis tshua muaj hlau hlau tuaj yeem sib txawv nyob ntawm qib. Piv txwv li, cov qib ib txwm muaj peev xwm muaj zog ntawm ib puag ncig 345 MPa. Lub zog tawm los yog qhov kev ntxhov siab uas cov khoom pib nthuav tawm cov yas deformation mus tas li. Hauv kev siv cov txheej txheem, cov cuab yeej no tseem ceeb heev vim nws txiav txim siab qhov siab tshaj plaws uas tus qauv tuaj yeem dais yam tsis muaj kev hloov pauv tseem ceeb thiab ruaj khov.

Tensile zog: Lub zog tensile sawv cev rau qhov siab tshaj plaws uas cov khoom tuaj yeem tiv taus ua ntej tawg. Nws yog feem ntau siab dua lub zog tawm los thiab tuaj yeem nyob ib ncig ntawm 470 MPa mus rau ntau dua 620 MPa. Qhov sib txawv ntawm lub zog tawm los thiab lub zog tensile muab qhov qhia txog cov khoom siv ductility. Qhov sib txawv loj dua implies ntau ductility, lub ntsiab lus ntawm cov khoom yuav undergo ntau yas deformation ua ntej tsis ua hauj lwm.

Ductility thiab Elongation

Ductility yog lub peev xwm ntawm cov khoom siv los rub tawm lossis plastically deformed yam tsis muaj kev tawg. Elongation yog ib qho kev ntsuas ntawm ductility thiab feem ntau yog qhia raws li qhov feem pua ​​​​nce ntawm qhov ntev ntawm cov qauv kuaj thaum lub sij hawm ntsuas tensile. Tsawg- alloy steel qauv phaj feem ntau muaj qee theem ntawm elongation, uas tso cai rau lawv los ua cov duab sib txawv thaum tsim. Piv txwv li, ib qho elongation ntawm ib ncig ntawm 17 - 22% feem ntau yog rau ntau qib, ua rau cov hlau yuav khoov lossis dov rau hauv cov khoom siv xws li kab teeb thiab kab.

Impact Toughness

Kev cuam tshuam toughness yog ntsuas siv cov kev ntsuam xyuas zoo li Charpy V - notch test. Cov txiaj ntsig ntawm cov kev ntsuam xyuas no qhia tau hais tias cov khoom siv tuaj yeem tiv taus qhov cuam tshuam sai npaum li cas. Tsawg- alloy steel qauv phaj yog tsim los kom muaj kev cuam tshuam zoo rau kev tiv thaiv kev puas tsuaj los ntawm cov xwm txheej xws li av qeeg (hauv cov qauv), tsheb sib tsoo (hauv cov qauv choj), lossis cov khoom poob (hauv cov qauv tsim).

Chemical Properties thiab Corrosion Resistance

Lub luag haujlwm ntawm Alloying Elements hauv Corrosion Resistance

Qee cov ntsiab lus alloying ua lub luag haujlwm tseem ceeb hauv kev txhim kho corrosion ntawm cov hlau tsis tshua muaj hlau. Piv txwv li, chromium tsim ib txheej oxide passive rau saum npoo ntawm cov hlau, uas tiv thaiv nws los ntawm oxidation thiab corrosion. Nickel kuj tseem tuaj yeem txhim kho qhov kev tiv thaiv corrosion, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig nrog rau cov tshuaj lom neeg tshwj xeeb. Kev sib xyaw ua ke ntawm cov ntsiab lus alloying tuaj yeem ua rau cov hlau tiv taus ntau dua rau xeb thiab lwm yam corrosion, piv rau cov pa roj carbon steel.

Corrosion - Ib puag ncig zoo thiab tiv thaiv kev ntsuas

Nyob rau hauv ib puag ncig corrosive xws li cov ntug hiav txwv dej (vim ntsev - laden huab cua), kev lag luam chaw nrog tshuaj fumes, los yog underwater daim ntaub ntawv, yuav tsum tau ntxiv kev tiv thaiv. Cov no tuaj yeem suav nrog kev pleev xim, galvanizing, lossis siv lwm cov txheej txheem los txhim kho corrosion ntawm cov hlau tsis tshua muaj hlau hlau. Piv txwv li, nyob rau hauv ib tug ntug dej hiav txwv choj, lub steel qauv tej zaum yuav pleev xim rau nrog ib tug high-zoo anti-corrosive xim thiab tej zaum kuj muaj ib tug sacrificial anode system los tiv thaiv cov ntsev - dej corrosion.
