440—ʻO ke kila kila mea ʻoi kiʻekiʻe me ke kiʻekiʻe o ke kalapona kiʻekiʻe. Ma hope o ka mālama ʻana i ka wela kūpono, hiki ke loaʻa ka ikaika o ka hua kiʻekiʻe. Hiki i ka paʻakikī ke hōʻea i 58HRC, aia ma waena o nā kila kila paʻakikī loa. ʻO ka laʻana noi noi maʻamau ʻo "razor blades". ʻEkolu mau hiʻohiʻona e hoʻohana mau ʻia: 440A, 440B, 440C, a me 440F (maʻalahiʻano hana).
Kumuhana o ka poepoe kila kila:
ʻAʻole popo-hōʻoia nā kinipōpō kila, akā ʻaʻole maʻalahi i ka pala. ʻO ke kumumanaʻo ka hoʻohui ʻia o chromium, ua hoʻokumu ʻia kahi ʻāpana chromium oxide ma luna o ka kila, i hiki ke pale pono i ka hoʻopili hou ʻana ma waena o ke kila a me ka lewa, i hiki ʻole i ka oxygen i ka lewa ke komo i ka kila. kinipōpō, i laila e pale aku nei i ka hopena o nā popo hao e hao ana.
Ke hoʻohana nei ʻo China National Standards (CNS), Japanese Industrial Standards (jis) a me American Iron and Steel Institute (AISI) i ʻekolu mau helu e hōʻike ai i nā kila kila ʻokoʻa, i ʻōlelo nui ʻia i ka ʻoihana, kahi o ka moʻo 200 he chromium-nickel-manganese -based austenitic kuhiliʻole kila, 300 moʻo he chromium-nickel austenitic kuhiliʻole kila, 400 moʻo chromium kuhiliʻole kila (ʻike pinepine ʻia he hao hao), me martensite a me ferrit.
