AISI 4145H hlau

AISI 4145H Steel yog siv dav siv hlau hlau nrog cov qauv tshwj xeeb, tshuaj muaj pes tsawg leeg, thiab cov khoom zoo kawg nkaus.

Qauv:
Nws feem ntau ua raws li American Iron and Steel Institute (AISI) thiab lwm yam qauv kev lag luam.

Chemical Compositions:

• Cov pa roj carbon (C): Cov ntsiab lus carbon nyob rau hauv AISI 4145H steel feem ntau yog nyob rau hauv ntau ntawm ib feem pua, uas muab lub zog thiab hardness rau cov khoom.

• Manganese (Mn): Manganese muaj nyob rau hauv ib qho kev faib ua feem, ua rau cov hlau hardenability thiab toughness.

• Silicon (Si): Silicon yog ntxiv rau hauv ib qho nyiaj los txhim kho lub zog thiab txhim kho oxidation tsis kam.

• Chromium (Cr): Chromium cov ntsiab lus yog nyob rau hauv ib cheeb tsam, uas ua rau kom cov hlau hardness, hnav tsis kam, thiab corrosion kuj.

• Molybdenum (Mo): Molybdenum suav nrog ib feem pua ​​​​los txhim kho lub zog thiab hardenability.

• Sulfur (S) thiab Phosphorus (P): Cov ntsiab lus no muaj tsawg heev, vim tias cov sulfur thiab phosphorus ntau dhau tuaj yeem ua rau cov hlau tsis zoo.

Khoom:

• Mechanical Properties:

• Tensile Strength: AISI 4145H steel muaj lub zog tensile siab, ua kom nws muaj peev xwm tiv taus qhov hnyav thiab kev ntxhov siab.

• Yield Strength: Nws qhia tau hais tias lub zog tawm los, qhia txog kev ntxhov siab uas cov khoom pib deform plastically.

• Hardness: Cov hlau muaj qhov tshwj xeeb hardness ntau yam, muab kev tiv thaiv rau hnav thiab puas.

• Ductility: Nws qhia tau hais tias muaj qee qhov kev ductility, tso cai rau nws deformed yam tsis tau tawg yooj yim.

• Kev kho cua sov teb: Cov hlau no teb tau zoo rau cov txheej txheem kho cua sov xws li quenching thiab tempering. Quenching hardens cov hlau, thaum tempering txo brittleness thiab txhim kho toughness.

• Corrosion Resistance: Txawm hais tias tsis zoo li corrosion-resistant ib co stainless hlau, AISI 4145H steel muaj ib theem ntawm kev tiv thaiv corrosion nyob rau hauv ntau qhov chaw.

• Weldability: Nrog cov txheej txheem tsim nyog thiab kev ceev faj, AISI 4145H hlau tuaj yeem welded, ua rau nws tsim nyog rau fabrication thiab kho.

Hauv kev xaus, AISI 4145H steel yog ib qho tseem ceeb alloy steel nrog cov qauv zoo, cov tshuaj muaj pes tsawg leeg, thiab cov khoom siv zoo heev thiab lub cev. Nws versatility ua rau nws haum rau ntau yam kev siv hauv kev lag luam xws li roj thiab roj, tshuab tsim, thiab kev tsim kho.
