15Mo3 steel yeeb nkab yog lub siab hlab ntsha hlau. Nws muaj qhov ua tau zoo ntawm kev ua haujlwm kub thiab siab ua haujlwm. Nws yog tsuas yog siv nyob rau hauv boilers thiab siab hlab ntsha nyob rau hauv high kub thiab high-pressure ib puag ncig, raws li zoo raws li lwm yam Cheebtsam uas yuav tsum tau tiv taus kub thiab siab. Raws li pearlitic cua sov-cov hlau tsis muaj zog, nws yog qib steel uas khaws nws cov khoom ntawm qhov kub thiab txias thiab nyob rau hauv lub sijhawm ntev. Nws yog siv rau cua sov qhov chaw nyob rau hauv qis - thiab nruab nrab - siab boilers (kev khiav hauj lwm siab tsis tshaj 5.88 MPa, ua hauj lwm kub hauv qab no 450 degree).

Kev ua tau zoo ntawm 15Mo3 Alloy Steel Yeeb Nkab
Thaum tshav kub kub Resistance: 15Mo3 steel yeeb nkab qhia tau zoo heev thaum tshav kub kub tsis kam, tuav ruaj khov mechanical zog thiab creep kuj nyob rau hauv high kub.
Lub zog: Cov yeeb nkab steel no muaj lub zog ua haujlwm siab thiab lub zog tensile, ua rau nws tsim nyog rau cov khoom siv uas raug kev nyuaj siab.
Corrosion Resistance: Vim muaj qee qhov nyiaj ntawm chromium (Cr) thiab molybdenum (Mo), 15Mo3 tshav kub-cov yeeb nkab steel kuj muaj qee qhov kev tiv thaiv corrosion.
Weldability: Cov yeeb nkab steel hlau no nthuav tawm zoo weldability thiab tuaj yeem koom nrog thiab ua tiav siv ntau txoj kev vuam.
