1. Q: Dab tsi yog cov khoom siv ntawm 5160 steel yeeb nkab?
A: 5160 yog ib qho aisi - Txheem siab {cov ntsiab lus ntawm 0.70% rau 0.90% rau 0.75% rau 1.00%. Nws nta muaj txwv tsis pub muaj tsawg, qaug zog zoo heev, ua rau nws haum tshwj xeeb, ua rau nws haum rau cov kev cuam tshuam lossis kev siv hluav taws xob ntau dua.
2. Q: Dab tsi yog cov khoom siv kho tshuab uas raug ntawm 5160 steel yeeb nkab?
A: Tom qab quenching thiab tempering, lub tensile muaj zog tuaj yeem ncav cuag 950 MPa ntau dua los yog sib npaug ntawm 10 rau 50 (nyob ntawm cov txheej txheem kho cua sov). Nws cov matastic modulus (kwv yees li 200 GPA) ua rau nws xaiv qhov zoo tshaj plaws rau kev tshawb fawb thiab cov hlau tuam.
3. Q: Cov ntsiab lus ntawm kev kho cua sov yog dab tsi rau 5160? A: Nws yuav tsum tau Austenitization ntawm 830- 860℃ua raws li los ntawm cov roj quenching (cov ntoo khaub lig loj uas xav tau dej quenching). Tempering yog feem ntau ntawm 400-500℃kom ua tiav qhov sib npaug ntawm kev nyuaj thiab tawv. Ua tib zoo kom tsis txhob npau taws rau kev npau taws ntawm 300 degree. Rau cov ntawv thov caij nplooj ntoos hlav, Austempering (bainite kev kho mob) tuaj yeem siv los txhim kho kev qaug zog.
4. Q: Dab tsi yog qhov zoo ntawm 5160 piv rau 5155 steel yeeb nkab?
A: 5160 muaj ntau dua cov pa roj carbon thiab manganese cov ntsiab lus, ua rau muaj qhov zoo dua 5155. Txawm li cas los xij, nws yuav tsum tau sib tsoo lossis tshwj xeeb tooling. Thaum vuam, nws yuav tsum yog preheated rau saum 300℃thiab raug rau kev ntxhov siab annealing tom qab vuam.
5. Q: Dab tsi yog cov ntawv thov tseem ceeb rau 5160 tus yeeb nkab steel?
A: Nws yog feem ntau siv nyob rau hauv hnyav {{} dution nplooj springs, tej cuab yeej ntxiab, xws li axes thiab siab} kev ntxhov siab kho tshuab hlav. Nws yog dav siv nyob rau hauv kev siv cov tshuab kev kawm qeeb, Shocks Kev Nyab Xeeb rau kev tsim cov tshuab, thiab cov riam phom tub rog thiab tub rog.
