Mechanical zog:

* AISI 4130 muaj cov cuab yeej zoo heev. Nws lub zog tensile ntau yog 785-835 MPa, tawm lub zog ntau yog 590-620 MPa, thiab elongation ntau yog 19%-24%. Tsis tas li ntawd, nws cov quenchability yog qhov zoo, nrog rau qhov tseem ceeb quenching txoj kab uas hla ntawm cov roj mus txog 4 hli thiab hardness tus nqi ntawm HRC 38-43.

* Lub zog thiab tawv ntawm cov hlau no feem ntau yog vim nws cov ntsiab lus carbon siab thiab ntxiv ntawm chromium thiab molybdenum ntsiab. Cov ntsiab lus no ua rau cov hlau tsim cov pa roj carbon ntau dua thaum lub sijhawm quenching, yog li ua kom cov khoom tawv tawv thiab txhim kho nws lub zog tensile.

* Zoo quenchability tso cai rau AISI 4130 kom haum rau kev tsim cov khoom loj xws li cov iav thiab cov ncej.

* Kev ua haujlwm kub kub zoo thiab weldability ua rau AISI 4130 yooj yim rau kev ua thiab txuas.

Qhov zoo:

* AISI 4130 muaj lub zog siab thiab zoo toughness, uas tuaj yeem ua tau raws li qhov xav tau ntawm ntau yam kev ua haujlwm nyuaj.

* Nws muaj qhov zoo quenchability thiab tsim nyog rau kev tsim cov khoom loj.

* AISI 4130 muaj kev ua haujlwm kub zoo thiab weldability, uas yooj yim rau txheej txheem thiab txuas.

Qhov tsis zoo:

* Kev tiv thaiv corrosion ntawm AISI 4130 yog dav dav, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig xws li chlorides, nws cov corrosion kuj tsis zoo.

* Qhov rhiab heev ntawm AISI 4130 yog qhov muaj zog, thiab nws yog qhov ua rau tawg tawg thaum raug cuam tshuam.

Daim ntawv thov:

AISI 4130 yog dav siv nyob rau hauv ntau yam teb vim nws zoo heev mechanical zog thiab zoo quenchability. Nws yog feem ntau siv rau kev tsim khoom uas yuav tsum tau muaj zog thiab toughness, xws li loj-section qhov chaw xws li shafts, bolts, gears, txuas rods, thiab lwm yam cov khoom tseem ceeb. Hauv kev tsim kho kev lag luam, nws yog siv rau kev tsim cov khoom hnyav xws li txuas hniav thiab kev loj guardrails, thiab lwm yam.

Lub teb chaws cov lis dej num sib xws:

* Hauv Nyij Pooj, cov npe sib xws rau AISI 4130 yog SCM430.

* Hauv Kaus Lim Qab Teb, cov npe sib txuas rau AISI 4130 yog STS4130.

* Hauv Tebchaws Europe, cov khoom lag luam sib raug rau AISI 4130 yog 25CrMo4.

Hauv cov ntsiab lus, AISI 4130 chromium-molybdenum alloy steel yog ib qho zoo heev nruab nrab carbon alloy steel nrog cov neeg kho tshuab zoo heev.
