4145H thiab 4145H MOD yog ob qhov sib txawv steel specifications tsuas yog siv rau kev siv zog thiab kub kub hauv kev lag luam roj av thiab roj. Lawv qhov sib txawv nyob hauv cov hauv qab no:
Tshuaj muaj pes tsawg leeg: Muaj qhov sib txawv me ntsis ntawm cov tshuaj muaj pes tsawg leeg ntawm 4145H thiab 4145H MOD. Nquag, 4145H MOD muaj cov ntsiab lus carbon ntau dua thiab qee cov ntsiab lus alloying xws li molybdenum, chromium, npib tsib xee, thiab lwm yam tau ntxiv los muab lub zog zoo dua thiab tiv thaiv corrosion. Kev kho cua sov: 4145H thiab 4145H MOD steel tau txais kev kho cua sov sib txawv. 4145H tau txais kev kho mob quenching thiab tempering, thaum 4145H MOD feem ntau yuav tsum tau quenching thiab normalizing kev kho mob los txhim kho nws lub zog thiab toughness. Cov kev cai tshwj xeeb: 4145H MOD steel feem ntau ua tau raws li cov kev cai nruj dua thiab cov qauv kom hloov mus rau qhov chaw tshwj xeeb. Nws yuav tsum tau ua kom tau raws li qhov xav tau ntau dua rau kev cuam tshuam toughness, ductility, thiab corrosion kuj los xyuas kom meej kev nyab xeeb thiab kev ntseeg siab nyob rau hauv huab cua txias.
4145H thiab 4145HMOD yog ob qho khoom siv stabilizer. Lawv txawv me ntsis hauv lawv daim ntawv thov teb thiab cov yam ntxwv ua haujlwm.
4 145h
Qhov zoo:
-High lub zog: 4145H muaj lub zog tensile thiab yield zog, ua rau nws haum rau cov ntawv thov uas yuav tsum tau muaj zog.
-Corrosion resistance: Cov khoom no muaj qhov zoo corrosion kuj thiab tuaj yeem siv rau hauv qhov chaw hnyav.
Qhov tsis zoo:
-Kev ua haujlwm tsis zoo: 4145H nyuaj rau kev ua haujlwm thiab yuav tsum tau siv cov cuab yeej tshwj xeeb thiab cov txheej txheem rau kev ua haujlwm.
-Tus nqi siab: Vim nws lub zog siab thiab corrosion kuj, tus nqi ntawm 4145H feem ntau yog siab dua.
4145 HMO
Qhov zoo:
-Zoo dua weldability: Piv rau 4145H, 4145HMOD muaj weldability zoo dua, ua rau nws yooj yim rau vuam nrog lwm yam khoom.
-Crack resistance: Cov khoom siv no muaj kev tiv thaiv zoo heev thiab tsim nyog rau cov ntawv thov uas xav tau kev tiv thaiv kev tawg.
-Zoo heev toughness: 4145HMOD muaj siab toughness thiab muaj peev xwm tuav tau zoo nyob rau hauv kev nyuaj siab.
Qhov tsis zoo:
-Muaj zog qis dua: Piv rau 4145H, lub zog tensile thiab lub zog tawm los ntawm 4145HMOD yog me ntsis qis.
-Poor corrosion kuj: Piv rau 4145H, 4145HMOD muaj me ntsis corrosion kuj.
Cov ntaub ntawv tsim nyog yuav tsum raug xaiv raws li kev thov tshwj xeeb. Yog tias muaj qhov yuav tsum tau ua kom muaj zog thiab vuam tsis tas yuav tsum tau, 4145H tuaj yeem xaiv. Yog hais tias weldability zoo dua, tawg tsis kam, thiab toughness yog yuav tsum tau, thiab kev sib haum xeeb ntawm lub zog yog txaus, ces 4145HMOD tej zaum yuav yog ib tug zoo xaiv.
Hauv cov ntsiab lus, 4145H MOD steel txawv ntawm 4145H hlau zoo tib yam hais txog cov tshuaj muaj pes tsawg leeg, kev kho cua sov, thiab cov kev cai tshwj xeeb kom tau raws li qhov xav tau ntawm lub zog siab dua thiab kev tiv thaiv corrosion. Kev xaiv tshwj xeeb ntawm cov hlau yog nyob ntawm qhov tshwj xeeb daim ntawv thov scenario thiab kev xav tau.
