38Cr4, 1.7043,37Cr4, 1.7034 alloy hlau

38Cr4 (1.7043) thiab 37Cr4 (1.7034) yog hom hlau alloy uas muaj cov khoom zoo kawg nkaus thiab nrhiav kev siv dav hauv ntau yam lag luam.

Cov hlau alloys no paub txog lawv cov khoom siv zoo heev. Lawv muaj lub zog tensile siab thiab lub zog tawm los, ua rau lawv tiv taus cov khoom hnyav thiab kev ntxhov siab. Qhov no ua rau lawv zoo tagnrho rau kev siv hauv cov khoom siv thiab cov tshuab ua haujlwm uas xav tau kev ua haujlwm ntev thiab kev ntseeg siab.

Qhov sib ntxiv ntawm chromium rau cov hlau no txhim kho lawv cov tawv tawv thiab hnav tsis kam. Chromium tsim ib txheej tiv thaiv oxide rau ntawm qhov chaw, muab kev tiv thaiv corrosion thiab oxidation. Qhov no yog qhov tseem ceeb tshwj xeeb hauv cov ntawv thov uas cov hlau raug cuam tshuam rau qhov chaw hnyav lossis qhov tsis kam hnav yog qhov tseem ceeb.

Ntxiv rau qhov muaj zog thiab hnav tsis kam, 38Cr4 thiab 37Cr4 alloy steels kuj muaj kev ua haujlwm zoo. Lawv tuaj yeem ua tau yooj yim zoo li tus thiab ua tiav siv ntau yam kev siv tshuab, tso cai rau kev tsim cov khoom siv nrog cov qhov ntev.

Cov tshuaj muaj pes tsawg leeg ntawm cov hlau no muaj xws li carbon, chromium, thiab lwm yam alloying ntsiab nyob rau hauv cov proportions. Cov ntsiab lus carbon muab hardness thiab lub zog, thaum lub chromium pab txhawb rau corrosion kuj thiab hardenability. Lwm cov ntsiab lus yuav raug ntxiv los txhim kho cov khoom tshwj xeeb xws li toughness lossis ductility.

Kev kho cua sov tuaj yeem siv rau cov hlau alloy no los kho lawv cov khoom siv kho tshuab. Cov txheej txheem quenching thiab tempering tuaj yeem ua kom tawv thiab lub zog, thaum annealing tuaj yeem txhim kho ductility thiab machinability.

Cov hlau no tau siv dav hauv kev lag luam xws li automotive, aerospace, thiab mechanical engineering. Lawv feem ntau pom muaj nyob rau hauv cov khoom xws li iav, ncej, bolts, thiab springs. Lawv ua ke ntawm lub zog, hnav tsis kam, thiab corrosion kuj ua rau lawv cov ntaub ntawv tseem ceeb rau cov ntawv thov no.

Hauv kev xaus, 38Cr4 (1.7043) thiab 37Cr4 (1.7034) alloy steels yog cov ntaub ntawv ua tau zoo nrog cov khoom siv zoo heev thiab kev tiv thaiv corrosion. Lawv versatility thiab kev cia siab rau ua rau lawv nrov xaiv nyob rau hauv ntau yam lag luam, thiab lawv cov yam ntxwv tshwj xeeb pab kom lawv ua tau raws li qhov xav tau ntawm cov kev siv sib txawv.
