Nā hiʻohiʻona huahana
1. Ka hoʻomaluʻana i ka hao a me ka chromium ma ka haʻahaʻa haʻahaʻa, e pale ana i ka hanauna o β-phase NI4MO.
2. ʻOi aku ka maikaʻi o ka corrosion kūʻē i ka hōʻemi ʻana i nā kaiapuni.
3. Kūʻē maikaʻi loa i ka ʻike waena o ka sulfuric acid a me ka nui o nā ʻakika non-oxidising.
4. Ke kū'ē maikaʻi loa i ka chloride ion ho'ēmi stress corrosion cracking (SCC).
5. Kūʻē maikaʻi i ka ʻino ʻana o nā ʻakika organik like ʻole.
