1. Cov khoom txhais thiab cov khoom tseem ceeb
Q: Dab tsi yog ovm 519 5132 cov yeeb nkab?
A:
5132 cov yeeb nkab steel yog ib qho nruab nrab-carbon chromium alloy steel seamless yeeb (tsis muaj G51320) teev nyob rau hauv Astm ATTM A519 tus qauv. Nws cov tub ntxhais muaj composition yog 0.30% -0.35% carbon thiab 1.00% -1.30% chromium. Cov khoom siv no, engineered nrog lub siab chromium cov ntsiab lus, ua tiav lub zog siab tshaj plaws (Tensile lub zog ntau dua lossis sib npaug ntawm cov khoom siv ntau dua (Hardness 50-54 HRC). Tom qab quenching thiab tempering, nws ua tiav cov ntsiab lus carbide ntawm 4% thiab zoo heev siab-kub tempering ruaj khov (hardness poob ntawm 500 degree<8%), making it particularly suitable for heavy-load transmission components.
2. Cov Khoom Siv Cov Neeg Kho Tshuab thiab Cov Lus Qhia
Q: Qhov kev ua tau zoo ntawm 5132 yeeb nkab steel?
A:
Hauv lub xeev quenched thiab tempered (870℃roj quenching+ 560 deg℃tempering):
Lub zog cov khoom: tensile zog 900-1100 MPa, tawm lub zog 750-900 mpa
Kev nyuaj: elongation ntau dua los yog sib npaug ntawm 12%, txo thaj chaw ntau dua lossis sib npaug nrog 40%, kev cuam tshuam hluav taws xob lub zog loj dua los yog sib npaug rau 30j
Cov Khoom Tshwj Xeeb: Sib cuag Kev Ua Rog Rog Lub Neej (10⁷ Cycles) 20% Ntau dua 5130% Ntau dua 5130% LIS-LESTIVE ZOO TSHAJ PLAWS LOSSIS LOS NTAWM 80%
3. Cov ntawv thov raug
Q: Cov ntaub ntawv thov ntawm 5132 cov yeeb nkab tau dab tsi?
A:
Cov Machinery (cov crusher loj Shafts, ntaub thaiv ntaub thaiv cov ntaub thaiv cov ntaub thaiv cov tshuab txiav
Cov Khoom Siv Hluav Taws Xob: Cua Turbine Main Ncej Cov Kabmob Rooj, Roj Laum Yeeb Nkab
Cov Khoom Siv Tub Rog: Cov Cuab Yeej Tsheb Tsheb Log Axles, Cov Khoom Siv Thauj Sib Tw Sib Hloov Hluav Taws Xob (yuav tsum xeem dhau MIL-S-6050 TESTING)
4. Cov ntsiab lus tseem ceeb rau kev kho cua sov thiab kev ua
Q: Yuav ua li cas thiaj ua tau kev kho kom sov thiab ua cov 5132 steel yeeb nkab? A:
Tus "sub-thermal deformation + Carbide Controlment" cov txheej txheem yuav tsum tau siv:
Sov rolling hauv thaj av ob-theem (790 degree) rau deformation ntawm 15% -20%, ua raws li cov roj quenching
Cryogenic kev kho (-80℃rau 6 teev) los txo cov Austen tau
Ob-kauj ruam tempering (350℃rau 2 teev → 550℃rau 4 teev)
Txwv tsis pub txwv:
Vuam yuav tsum tau ernicrmo-3 hlau thiab preheating rau 300 degree
Tig tau tsuas yog txwv rau altin-coated cuab yeej (txiav ceev 60-80 m / min)
5. Piv nrog cov ntaub ntawv zoo sib xws
Q: Qhov sib txawv ntawm 5132, 5140, thiab 4132 kav hlau? A:
vs . 5140}: 5132 muaj cov ntsiab lus chromium ntau dua (1.10%
vs. 4132: 5132 contains no molybdenum, resulting in a 15% lower cost, but its high-temperature strength (>300 degree) tsuas yog 70% ntawm 4132.
Tsis muaj qhov hloov chaw ntawm lub hauv paus: Hloov 4340 hlau rau Aviation-qib siab-lub tsheb khiav ceev.
