10Ni14 yog qhov kub-kub alloy steel yeeb nkab uas muaj kev tiv thaiv zoo heev thiab tsim nyog rau kev siv ua haujlwm ntawm qhov kub thiab txias. Cov khoom muaj li ntawm 10% npib tsib xee thiab lwm yam alloying ntsiab uas pab txhim kho cov hlau lub zog thiab toughness.
10Ni14 cryogenic steel kavyog dav siv nyob rau hauv kev tuav thiab kev thauj mus los ntawm liquefied gases thiab lwm yam cryogenic kua, tshwj xeeb tshaj yog nyob rau hauv cia thiab tsheb thauj mus los systems ntawm liquefied natural gas (LNG) thiab liquefied petroleum gas (LPG). Vim nws cov khoom siv kho tshuab zoo thiab lub zog siab, cov yeeb nkab steel no tuaj yeem tiv taus cov kev ntxhov siab loj hauv qhov kub thiab txias yam tsis muaj kev tawg.

10Ni14 alloy structural steel yeeb nkab yog ib qho tshwj xeeb kho steel nrog ntau dua concentration ntawm alloying ntsiab kom muab zoo corrosion kuj, kub kuj thiab hnav tsis kam. Cov hlau no kuj muaj lub zog tawm los, lub zog tensile, lub zog ruaj khov thiab txaus yas thiab toughness, nrog rau qhov tsis tshua muaj txiaj ntsig-rau-lub zog piv, feem ntau nyob ib ncig ntawm 0.85.
Kev tsim cov hlau alloy no feem ntau siv cov txheej txheem xws li hluav taws xob arc rauv (EAF), nqus degassing (VD) thiab LF refining kom ntseeg tau tias nws muaj lub cev zoo thiab cov khoom siv kho tshuab. Tsis tas li ntawd, yog tias yuav tsum tau ua kom tau raws li cov ntawv thov tshwj xeeb, cov txheej txheem electroslag refining (ESR) kuj tseem siv tau.
