ʻO ke kila kalapona hoʻolei ke ʻano o ke kila hoʻolei ʻia me ke kalapona ma ke ʻano he mea hoʻohui nui a me kahi mea liʻiliʻi o nā mea ʻē aʻe. Hiki ke hoʻokaʻawale ʻia ke kila kalapona i hoʻolei ʻia i ke kila kalapona haʻahaʻa, ke kila kalapona waena a me ke kila kalapona kiʻekiʻe. ʻO ka maʻiʻo kalapona o ke kila kalapona haʻahaʻa haʻahaʻa ma lalo o 0.25%, ʻo ka maʻiʻo kalapona o ke kila kalapona i hoʻolei ʻia ma waena o 0.25% a me 0.60%, a ʻo ka ʻike kalapona o ke kila kalapona kiʻekiʻe ma waena o 0.6% a me 3.0%. Nā hiʻohiʻona hana o nā hoʻolei kila:
- • ʻAʻole nui ka liʻiliʻi a me ka liʻiliʻi a me ka laina laina
- • He mea kiʻekiʻe ka waiwai mechanical comprehensive. Ua like ka ikaika compressive a me ka ikaika tensile
- • ʻAʻohe haʻalulu haʻalulu a me ke kiʻekiʻe notch sensitivity
- • Haʻahaʻa kalapona kila castings loaʻa maikaʻi weldability.
