Ultra siab zog steel nrog carbon dawb (los yog micro carbon) martensite raws li lub matrix, uas yuav ua tau intermetallic compound nag lossis daus hardening thaum laus. Sib txawv ntawm cov tsoos high-strength steel, nws muaj zog los ntawm dispersion ntawm intermetallic tebchaw es tsis txhob 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.
Maraging steel yog ib qho ntawm cov hlau uas muaj zog heev. Qhov zoo tshaj plaws ntawm cov hlau no yog cov txheej txheem kev kho cua sov yog qhov yooj yim thiab yooj yim. Tom qab kev daws teeb meem, nws yog machined ua ntej thiab tom qab laus. Kev kho cua sov deformation yog me me, thiab kev ua haujlwm thiab vuam khoom zoo. Cov txheej txheem kev kho cua sov thiab cov khoom ntawm maraging steel yog qhia hauv cov lus hauv qab no. Nyob rau hauv xyoo tas los no, cov pwm ua los ntawm maraging steel yog dav siv txawv teb chaws; Tab sis nyob rau hauv Suav teb, maraging steel yog ib qho nyuaj rau siv dav vim nws cov ntsiab lus siab thiab tus nqi siab ntawm Ni, Co thiab lwm yam khoom muaj nqi hlau. Cov hlau no tsuas yog siv rau precision forging tuag thiab yas tuag.
