GNEE STEEL yog tsev neeg cov khoom siv hlau. Peb cov ntaub ntawv npog npog dav dav, catering rau ntau yam kev lag luam thiab kev lag luam.
Dab tsi yog cov ntawv thov kev lag luam ntawm 20Mn2 alloy steel?
1. Taw qhia rau 20Mn2:
20Mn2 yog cov khoom siv steel qib uas tau teev tseg hauv Suav tus qauv GB / T 3077, uas txhais tau hais tias cov hlau no feem ntau yog tsim los ntawm carbon (C), manganese (Mn) thiab ib feem ntawm silicon (Si). 20Mn2 yog ib qho tsis tshua muaj carbon manganese hlau nrog zoo weldability, forgeability thiab plasticity.
2. Cov tshuaj muaj pes tsawg leeg ntawm 20Mn2 steel yog:
- Carbon (C) cov ntsiab lus: 0 17-0.24%
- Manganese (Mn) cov ntsiab lus: 1.40-1.80%
- Silicon (Si) cov ntsiab lus: 0.17-0.37%
- Phosphorus (P) cov ntsiab lus: Tsawg dua lossis sib npaug rau 0.035%
- Sulfur (S) cov ntsiab lus: Tsawg dua lossis sib npaug rau 0.035%
3. 20Mn2 kev lag luam daim ntawv thov:
Cov hlau no feem ntau yog siv los ua cov khoom siv tshuab thiab cov khoom siv xws li lub zog, bearings, pins, thiab lwm yam. Qhov sib ntxiv ntawm manganese tuaj yeem txhim kho lub zog thiab lub zog ntawm cov hlau, ua kom cov hardness qhov tob, thiab txhim kho cov cua sov kho hardening peev xwm ntawm steel. Nyob rau tib lub sijhawm, vim nws cov ntsiab lus carbon tsawg, 20Mn2 muaj qhov zoo weldability thiab txias deformation zog.
4. 20Mn2 cov qauv kev coj ua:
Raws li tus qauv GB / T 3077, txoj kev kho cua sov ntawm 20Mn2 yog normalizing kev kho mob lossis quenching thiab tempering kho kom tau txais cov khoom siv kho tshuab. Thov nco ntsoov tias hauv cov ntawv thov tshwj xeeb, kev xaiv cov khoom siv thiab kev kho cua sov tsim qauv kuj yuav tsum tau ua raws li cov kev xav tau ntawm engineering thiab kev siv. Nws yog qhov zoo tshaj rau kev xaiv cov khoom siv thiab kev ua haujlwm raws li kev taw qhia ntawm cov kws tshaj lij.
