4145H yog cov txheej txheem steel feem ntau siv rau kev tsim thiab siv cov cuab yeej siv roj zoo. Cov hlau yog ua tiav hauv qhov cub hluav taws xob thiab ua tiav los ntawm cov tshuab ua kom zoo. Tsis tas li ntawd, cov roj xyaum siv feem ntau yog siv los txhim kho kev ua haujlwm ntawm cov khoom siv laum. Thaum siv 4145H steel nyob rau hauv cov qhov dej taw qhia, nws muaj peev xwm mus laum ntawm qis torque thiab kev kub ceev, yog li txo qhov hnav thiab kev puas tsuaj rau cov ncej drilling.
Vim yog cov khoom me me ntawm 4145H steel thiab qhov chaw sib cuag me me nrog lub qhov drilling, nws nyuaj rau tsim daim npav sib txawv. Cov yam ntxwv no ua rau 4145H steel ntau txhim khu kev qha hauv kev ua haujlwm drilling, thaum txo kev sib txhuam nrog lub qhov dej thiab qhov tsis tsim nyog poob.
Cov tshuaj muaj pes tsawg leeg ntawm 4145H steel kuj yog tus yuam sij rau nws cov kev ua tau zoo heev. Qhov tsim nyog piv ntawm cov tshuaj muaj pes tsawg leeg tuaj yeem ua kom muaj kev ruaj khov ntawm cov hlau hauv qhov chaw nyuaj xws li qhov kub thiab txias. Feem ntau, cov tshuaj muaj pes tsawg leeg ntawm 4145H hlau muaj xws li carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), chromium (Cr), thiab nickel (Ni). Cov ntsiab lus thiab qhov sib piv ntawm cov ntsiab lus no tuaj yeem hloov kho raws li cov kev xav tau tshwj xeeb kom ua tau raws li qhov xav tau ntawm cov ntawv thov sib txawv.
Raws li ib tug high-lub zog alloy steel, nws yog dav siv nyob rau hauv kev tsim ntawm forgings thiab muaj cov nram qab no zoo:
Lub zog siab: 4145H muaj lub zog muaj zog thiab lub zog tensile, tso cai rau forgings kom tiv taus ntau dua thiab kev ntxhov siab. Qhov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas xav tau cov ntaub ntawv muaj zog. Zoo hnav tsis kam: Vim yog qhov sib ntxiv ntawm cov ntsiab lus alloying, 4145H muaj kev hnav zoo thiab tuaj yeem tiv taus qhov cuam tshuam ntawm hnav, abrasive hais, thiab kev sib txhuam. Qhov no ua rau cov khoom siv zoo heev rau forgings siv hauv kev sib txhuam siab thiab hnav ib puag ncig. Zoo toughness: 4145H muaj kev cuam tshuam zoo toughness thiab tuaj yeem tswj cov qauv ruaj khov thiab kev ua tau zoo nyob rau hauv kev cuam tshuam lossis kev co. Qhov no ua rau forgings ua haujlwm nyob rau hauv cov xwm txheej hnyav thiab muaj kev nyab xeeb siab. Ib qho yooj yim rau txheej txheem: Txawm hais tias 4145H yog cov hlau muaj zog, nws tseem muaj cov khoom ua haujlwm zoo. Nws tuaj yeem tsim thiab ua tiav los ntawm cov txheej txheem xws li forging, kev kho cua sov, thiab kev siv tshuab ua kom tau raws li qhov xav tau ntawm cov duab sib txawv thiab ntau thiab tsawg. Corrosion kuj: 4145H muaj corrosion kuj zoo heev, tshwj xeeb tshaj yog nyob rau hauv kub thiab av noo ib puag ncig. Qhov no ua rau forgings kom muaj kev ruaj ntseg nyob rau hauv ib puag ncig tshuaj lom neeg hnyav thiab txuas ntxiv lawv lub neej kev pab cuam.
Hauv cov ntsiab lus, daim ntawv thov ntawm 4145H steel hauv cov roj zoo drilling cov cuab yeej yog qhov tseem ceeb heev. Nws cov arc rauv ua thiab cov tshuab ua kom zoo zoo muab nws cov khoom siv zoo thiab ua haujlwm ntev. Qhov tsim nyog piv ntawm nws cov tshuaj muaj pes tsawg leeg ua kom ruaj khov ua haujlwm raws li kev ua haujlwm hnyav. Los ntawm kev tshawb fawb ntxiv thiab kev tsim kho tshiab, peb tuaj yeem cia siab tias 4145H steel los ua lub luag haujlwm ntau dua nyob rau yav tom ntej roj zoo drilling teb, txhim kho drilling efficiency thiab txo cov nqi.
