Hardness tswj ntawm cov hmoov metallurgy cov khoom lag luam thaum kho cua sov:

Qhov ntom ntawm cov hmoov atomized (xws li carbon steel thiab tooj liab-carbon alloy steel) yog siab dua 6.9, thiab quenching hardness yuav tswj tau nyob ib ncig ntawm HRC30.

Feem ntau, qhov ceev ntawm pre-alloyed hmoov (AB hmoov) tshaj 6.95, thiab quenching hardness yuav tswj tau nyob ib ncig ntawm HRC35.

High prealloyed hmoov nrog ntom ntau dua 6.95 thiab quenching hardness tswj ntawm HRC40.

Cov hmoov hlau tawv me me tau ua los ntawm cov khoom siv saum toj no muaj qhov ruaj khov thiab siv zog ua kom muaj zog thiab lub zog compressive yuav mus txog lub ncov zoo dua.

Puas tuaj yeem kho cua sov hardness ntawm hmoov metallurgy ncav cuag 45 steel? Tau kawg koj tuaj yeem ua tau!

Txawm li cas los xij, vim tias qhov ntom ntawm PM cov khoom tsis siab li ntawm No. 45 steel, qhov siab tshaj plaws ntawm PM nias qhov feem ntau yog 7.2 g / cm3, thaum qhov ntom ntawm No. 45 steel yog 7.9 g / cm.Forced carburizing. ntawm hmoov metallurgy los yog kev kho cua sov ntau tshaj li HRC45 yuav ua rau cov hmoov metallurgy cov khoom nkig vim siab quenching, uas ua rau lub zog ntawm cov hmoov metallurgy khoom.

Tom ntej no, peb yuav muab piv rau P / M sib sau iav nrog cov machined hobbing iav.

1. Kev siv cov khoom siv siab, txog li 95%

2. Tsis muaj lossis tsuas yog txiav me ntsis xwb

3. Zoo qhov sib xws ntawm qhov chaw, zoo stability thiab siab precision.

4. Kev sib piv lub zog: cov kws tshaj lij hmoov metallurgy tuam ntxhab tau ua kom zoo dua cov hmoov hlau metallurgy pwm tsim, thiab lub zog tensile thiab compressive lub zog ntawm cov iav tsim tau nyob ze rau ntawm cov iav hobbing.Piv txwv li, lub zog tsav ntawm lub tsheb gearbox nrog siab kis tau tus mob. kev siv kuj yog hmoov metallurgy iav.pom, hmoov metallurgy iav yog cov tswv yim thiab dav.

5. hmoov nias molding siv cov pwm molding, tuaj yeem tsim lwm yam kev txiav hobbing tshuab tsis tuaj yeem tsim cov duab nyuaj.

6. Vim tias nws yog qhov tsim nyog rau kev tsim khoom loj, kev ua haujlwm ntau lawm yog siab thiab tus nqi qis dua txiav.

7. Haum rau kev tsim khoom loj, yog li tus nqi sib tw kiag li.
