1. Dab tsi yog qhov yooj yim txhais ntawm 519 50 b44 cov yeeb nkab steel?
Nws yog seamless neeg kho tshuab steel yeeb nkab teev nyob rau hauv Astm ATTM A51MNT cov qauv 50b44 lossis Suav {{{{}} manganese steel).
Composition: Carbon Cov Ntsiab Lus 0.40-0.46%, manganese 1.35-1.65%, tsis muaj chromium ntxiv. Tus nqi yog qis dua li alloy steel, tab sis lub zog yog zoo dua rau cov carbon steel.
2025 Nco tseg: Vim Tsis ntev los no hloov pauv hauv Manganese OR (+12}}}}}}}}} Cov khoom siv tau nce me ntsis.
2. Dab tsi yog cov ntawv thov tseem ceeb ntawm cov yeeb nkab steel?
Hnyav {{{0} {Dute} Desise} Desise}: xws li Shafts rau cov khoom siv tsuas rau kev siv tshuab, uas yuav tsum tau tiv thaiv kev cuam tshuam zoo.
Automotive Spressices: qee lub tsheb lag luam nce qib thiab Universal cov koom haum sib koom ua ke (txo qis hauv cov tsheb hluav taws xob tshiab).
Hydraulic Lub Tog Raj Kheej Raug Tshab: Siv Hauv Nruab Nrab {}}}}}}}} Kos Duab Precision Machining. Cov Lus Qhia Sib Tham: Nrog kev tsim kho cov ntse xav tau los ntawm 2025, siab} Lub zog alloys yuav hloov qee cov ntawv thov, tab sis cov ntawv thov ib txwm tseem yuav ua tus kav.
3. Nws muab nws piv rau cov qhab nia zoo sib xws (xws li 50b46)?
Kev sib xyaw sib txawv: 50b44 muaj cov ntsiab lus roj carbon monoxent me ntsis (0.40-0.46% vs {}
Tus nqi - ua tau hauj lwm zoo: 50b44 yog qhov tsim nyog rau tus nqi uas tsis xav tau lub zog muaj zog, xws li tshuab ua liaj ua teb
Kev ua haujlwm: ob qho tib si yuav tsum tau ua ntej rau vuam, tab sis 50b44 muaj qhov pheej hmoo tsawg dua ntawm kev tawg thaum lub sij hawm txias.
4. Cov kev ua tau tseem ceeb thiab kev pom zoo ua kom sov
Lub zog tensile: kwv yees li 750 - 900 mpa nyob rau hauv lub xeev kub, mus txog ntawm 1000 tom qab quenching thiab temching.
Txheej txheem kev kho cua sov: quenching (dej txias) + tempering (500-600 ° C) yog pom zoo kom sib npaug lub zog thiab tawv. Kev Lag Luam Kev Lag Luam: los ntawm 2025, Doid Steel Mills yuav dav siv thev naus laus zis online Resided Technology, txo cov nqi los ntawm 15%.
5. Kev Pab Cuam thiab Kev Tswjhwm Zoo
Tus Qauv Sab Laj: Cov Intern Dity Dag yog ± 0.8% (ASTM A519), sab hauv ib sab yuav tsum pub dawb ntawm nplai.
Yuav tsum tau kuaj cov kev kuaj: Yuav tsum tau tshuaj ntsuam xyuas suav nrog kev kuaj ultrasonic (UN) thiab Hardness Testing (HB 241-302).
Cov ntaub ntawv pov thawj: ib feem peb {{{{{{{{}}}}}}}}}}}}}}}}}}}}}}}}}}} Tsom nias, tsom mus rau manganese thiab cov lus faj sulfur (ultrasonic40%).
