Okulonda ekyuma ekinyogoza ekiziyiza (quenching cooling medium) kusinga kulowoozebwako mu nsonga zino wammanga:
1, ekirungo kya kemiko eky’okwambala-ebintu ebiziyiza okusuulibwa, ebirimu mu bitundu bya aloy, naddala kaboni ali mu bitundu ebinene.
2, ekyuma austenitizing state ne hardenability, ne common isothermal enkyukakyuka diagram, continuous cooling transition diagram.
3, embeera y’ebintu eby’okwambala-okusuula okugumira (obutonde ne ddiguli y’ekikyamu).
4, Okulongoosa mu bbugumu okwambala-Okusuula ebiziyiza okwetaagisa okukola n'ensengeka, okwambala-Okusuula okuziyiza kwakkiriza okukyukakyuka okukyukakyuka obunene.
5. Sayizi, obuwanvu obulungi n’enkula obuzibu bw’okwambala-ebiziyiza ebiziyiza.
6. Omutendera gw’obukugu bw’abaddukanya emirimu.
7. Ensonga z’obutonde n’ebiragiro ebikwatagana.
Okulonda ekisengejja ekinyogoza ekizikira kitera okutegeeza ekipimo ky’engeri y’okunyogoza eky’omu makkati ekipimibwa nickel-ekikebera aloy eyesigamiziddwa (nga mw’otwalidde n’ebbugumu ery’engeri, omuwendo gw’okunyogoza ogw’amaanyi mu kitundu ky’ebbugumu eri wansi, omuwendo gw’okunyogoza ogw’okusinga obunene n’okusinga wansi n’obuwanvu bw’ebbugumu we bisangibwa, n’ebirala), awamu n’omuwendo gwa H ogw’amaanyi g’okugoba Hunching.
