Maraging300 (C300) siab zog thiab siab elastic maraging steel
Cov qib zoo sib xws: 18Ni300, Maraging 300, C300, 3J33, maraging steel
Maraging yog ib tug series ntawm maraging steel nrog npib tsib xee ntsiab lus ntawm 18 feem pua, thiab nws cov khoom yog txhim khu kev qha los ntawm kev ntxiv cobalt. Cov hlau no muaj cov khoom siv zoo heev, kev ua haujlwm thiab kev kho cua sov.
Maraging300 yog lub zog muaj zog heev raws li carbon-dawb (lossis micro-carbon) martensite, uas tuaj yeem tsim cov dej sib xyaw ua ke los nag lossis daus thaum laus. Tsis zoo li cov tsoos high-strength steel, nws muaj zog los ntawm dispersion ntawm intermetallic tebchaw tsis muaj carbon. Qhov no ua rau nws muaj qee yam khoom tshwj xeeb: siab zog thiab toughness, qis hardening Performance index, zoo formability, yooj yim kev kho cua sov txheej txheem, yuav luag tsis muaj deformation thaum lub sij hawm laus, thiab zoo welding kev kawm. Yog li ntawd, maraging steel tau dav siv nyob rau hauv lub department uas xav tau cov yam ntxwv zoo li no.
Txheej txheem ntau lawm:
Cov txheej txheem tseem ceeb muaj xws li smelting, kub ua, txias ua, vuam, kho cua sov thiab kho deg.
Smelting:
Feem ntau, ob chav nqus smelting txheej txheem ntawm lub tshuab nqus tsev induction rauv smelting thiab lub tshuab nqus tsev consumable furnace remelting yog saws. Non-vacuum smelting lossis non-vacuum smelting plus electroslag remelting txheej txheem tuaj yeem siv rau cov hlau nrog qib zog qis dua 1500MPa. Txawm li cas los xij, rau qib steel nrog lub zog siab thiab kev siv tseem ceeb, ob chav nqus smelting txheej txheem yuav tsum tau saws. Thaum lub tshuab nqus tsev consumable remelting, tam sim no thiab da dej kub yuav tsum tau nruj me ntsis tswj kom tsis txhob loj dendritic segregation ntawm ingots.
