Cov Ntsiab Lus Tseem Ceeb:
Chromium & molybdenum:Cov ntsiab lus siv alloy no muaj cov khoom nyuaj (muaj peev xwm ua kom tawv tawv, thiab kev nyuaj, tshwj xeeb, tshwj xeeb ntawm cov kub. Lawv kuj txhim kho corrosion tsis kam me ntsis piv rau cov txheej txheem carbon hlau.
Boron (b):Tus yam ntxwv tseem ceeb ntawm 1.0254 yog qhov sib ntxiv ntawm ib qho me me ntawm boron (feem ntau {%), uas cuam tshuam ntau dua uas tsis xav tau ntau qib ntxiv, ntau dua cov khoom kim.
3. Cov Khoom Siv Kho Tshuab
Cov khoom ntawm 1.0254 seamless yeeb nkab nyob ntawm seb nwsKev Kho Cua SovCov. Nws yuav luag ib txwm siv nyob rau hauvquenched thiab tempered (Q & T)mob.
Hauv quenched & tempered mob:
Tensile Lub Zog (RM):{{0900 - 1100 mpa mpa (kwv yees. 130},000 - 160, 000 psi)
Yield zog (RP0.2):Ntau dua los yog sib npaug rau 700 MPa (kwv yees li ntau dua lossis sib npaug rau 101,500 psi)
Elongation (a):Ntau dua los yog sib npaug rau 12%
Kev Cuam Tshuam Tougness (KV):Feem ntau> 40 J nyob rau hauv chav tsev kub.
4. Cov yam ntxwv tseem ceeb thiab cov txiaj ntsig zoo
Siab zog - rau - qhov hnyav. Piv:Tom qab kev kho cua sov, nws muaj zog heev, tso cai rau kev tsim qauv ntawm kev sib dua thiab ntau cov qauv txheej txheem.
Kev nyuaj heev:Nws tswj hwm cov kev cuam tshuam zoo thiab kev sib txawv txawm tias thaum muaj zog zog, ua rau nws tsis kam poob siab thiab qaug zog.
Cov tawv tawv zoo:Tus boron ntxiv tso cai rau cov hlau yuav tsum yog qhov nyuaj los ntawm cov ntawv tuab dua li cov qauv hlau txheem.
Weldability:Nws yog me ntsis weldable nrog cov txheej txheem tsim nyog (pre - cua sov thiab tshaj tawm kev kho cua sov feem ntau pom zoo, tshwj xeeb tshaj yog rau cov tuab tuab).
Machinability:Ncaj ncees nyob rau hauv anealed mob; ua qhov nyuaj dua tom qab kev kho cua sov.
5. Cov Ntawv Thov Tib Neeg
1.0254 Seamless kav yog siv nyob rau hauv qhov tseem ceeb, siab-} kev siv ntxhov siab:
Lub tog raj kheej thiab pneumatic lub tog raj kheej kheej:Nov yog lub tuam txhab ntawv thov. Qhov xwm yeem ua kom muaj kev kub siab, thiab lub zog siab yog qhov tseem ceeb rau lub tog raj kheej.
Automotive thiab Motorsport:Siv rau cov khoom tseem ceeb zoo liYob tawb, chassis tubing, ncua kev ncua sij hawm, thiab cov tsav camQhov twg muaj zog thiab lub teeb hnyav yog qhov tseem ceeb.
Neeg Kho Tshuab Engineering:Rau cov txheej txheem sib xyaw, piston pas nrig, zog, thiab lwm yam kev ntxhov siab ntau.
Roj & Roj Kev Lag Luam:Rau qee qhov cuab yeej downhole, cov kav dej siv, thiab lwm yam siab-} qhov kev siv siab.
