Kev kho cua sov ntsig txog
- Annealingntawm 60SI2MN Spring Steel
Maj mam rhuab mus rau 740-770 degree thiab cia lub sij hawm txaus, cia cov hlau kom sov kom huv si, Tom qab ntawd maj mam txias hauv qhov cub. 60SI2MN cov cuab yeej steel yuav tau MAX 250 HB (Brinell hardness).
- Hardening ntawm 60SI2MN Caij nplooj ntoos hlav hlau
60SI2MN steels yuav tsum tau rhuab uniformly mus rau 830-860 degree (1526-1580 degree F) kom txog thaum tag nrho rhuab los ntawm. Txog 30 min rau 25 hli ntawm cov lus txiav txim yuav tsum tau muab thiab tom qab ntawd cov hlau yuav tsum tau quenched tam sim hauv roj. Tau Hardness 61 Min.
- Tempering ntawm 60SI2MN Caij nplooj ntoos hlav hlau
Tempering ntawm 60SI2MN steels yog ua nyob rau ntawm 480-530 degree, Soak zoo ntawm qhov kub xaiv thiab tsau rau tsawg kawg ib teev ib 25 hli ntawm tag nrho cov tuab. Hardness qhov tseem ceeb ntawm qhov sib txawv kub tom qab tempering HRC: 150 degree -61HRc, 200 degree -60HRC, 300 degree -56HRC, 400 degree -51HRC, 500 degree {{13 }}HRC, 550 degree -38HRC, 600 degree -33HRC, 650 degree -29HRC.
