4130 steel yog cov hlau alloy uas feem ntau siv rau hauv ntau qhov haujlwm, thiab tsab xov xwm no yuav tshawb xyuas luv luv ntawm nws cov khoom. Los ntawm kev piav qhia txog nws qhov muaj pes tsawg leeg, lub zog, thiab kev siv, kab lus no tuaj yeem pab cov neeg nyeem txiav txim siab tias 4130 steel puas yog rau lawv txoj haujlwm tshwj xeeb. Peb yuav xub tshawb xyuas lub cev lub cev ntawm 4130 steel, ua raws li nws cov khoom siv kho tshuab, thiab thaum kawg nws cov ntawv thov, qhia qhov twg cov hlau no ci ntsa iab.
Lub cev muaj zog ntawm 4130 Steel
4130 steel tau txais nws lub npe los ntawm cov qauv tshwj xeeb tsim los ntawm AISI thiab SAE. Thawj tus lej ntawm cov alloy tsim cov chav kawm ntawm cov hlau, suav nrog nws cov ntsiab lus alloying. Tus lej thib ob sawv cev rau qhov feem pua ntawm cov alloying no thiab/lossis lwm yam tseem ceeb hauv theem nrab. Ob tug lej kawg sawv cev rau cov pa roj carbon ntau ntxiv ntawm 0.01 feem pua . Paub txog cov kev cai no, 4130 steel yog li ntawd ib feem ntawm 4xxx thiab 41xx series (chromium-molybdenum steels) nrog ib ncig ntawm 1 feem pua molybdenum / chromium los ntawm huab hwm coj nrog 0.30 feem pua carbon nrog. Txhawm rau kawm paub ntau ntxiv txog qhov sib txawv ntawm cov hlau, tsis txhob yig mus sab laj peb tsab xov xwm ntawm hom steels.
Hauv qab no yog cov tshuaj lom neeg muaj pes tsawg leeg ntawm 4130 steel, nrog rau kev zam:
0, 28 - 0, 33 feem pua Carbon
0,8 - 1,1 feem pua Chrome
0,7 - 0,9 feem pua Manganese
0,15 - 0,25 feem pua Molybdenum
Tsawg dua lossis sib npaug rau 0,035 feem pua phosphorus
0, 15 - 0, 35 feem pua Silicon
Tsawg dua lossis sib npaug rau 0,04 feem pua Sulfur
4130 steel yog chrome-molybdenum alloy hlau thiab suav hais tias yog cov hlau tsis muaj carbon. Nws muaj qhov ceev ntawm 7.85 g / cm3 (0.284 lb / hauv 3) thiab tau txais txiaj ntsig los ntawm kev kho cua sov hardening. Nws yog ib qho tshwj xeeb vuam hlau, ua weldable nyob rau hauv tag nrho cov kev lag luam txoj kev, thiab yog yooj yim machined nyob rau hauv nws normalized / hardened xeev. 4130 steel tuaj yeem ua haujlwm txias txias, ua haujlwm kub, thiab forged, tab sis nws tsis tuaj yeem muaj hnub nyoog. Nws muaj ductility zoo heev thaum av thiab yog los ntawm hardening alloy. 4130 steel ua tau zoo tshaj plaws raws li cov qauv hlau, thiab feem ntau pom zoo li lub raj raj lossis bar hauv cov qauv siv rau cov dav hlau thiab cov tsev.

Kev siv ntawm 4130 steel
Hom 4130 steel yog cov hlau tshwj xeeb, tseem ceeb rau kev tsim khoom, vuam, txiav, thiab lwm yam kev siv zog siab hauv kev lag luam. Nws cov yam ntxwv zoo rau kev kho cua sov muab nws lub siab tawv thiab, ua ke nrog nws cov kev ua haujlwm siab thiab kev ua haujlwm, ua rau 4130 steel dav siv tau. Txawm hais tias nws yog feem ntau siv los ua cov qauv hlau, muaj lwm yam kev siv tseem ceeb, xws li:
Kev tsim khoom siv rau bearings, tsheb qhov chaw thiab lub zog
pob zeb crushing machinery
Cov khoom siv vuam vuam
Drills thiab taps
Strawberries thiab cutters
thiab ntau ntxiv.
4130 steel yog cov khoom siv nrov thiab yooj yim rau kev ua haujlwm ntawm txhua yam. Yog tias koj xav tias 4130 steel yuav muaj txiaj ntsig zoo hauv koj cov qauv tsim, thov hu rau koj tus neeg muag khoom thiab nug seb lawv puas muaj nyob hauv Tshuag. Lawv feem ntau yuav muaj ntau, thiab yog tias lawv tsis ua, lawv yuav yog qhov zoo tshaj plaws ntawm cov ntaub ntawv rau lwm txoj hauv kev los xav txog.
