Hoʻopaʻahe mauhoʻopunipunimahopeke kalaiwa ana,ʻokiʻoki, mālama wela a me nā kaʻina hana'ē aʻe. I mea e hōʻoiaʻiʻo ai i ka maikaʻi o ka hana ʻana o ka make a hoʻemi i ke kumukūʻai hana, pono e loaʻa i ka mea malleability maikaʻi, machinability, hardenability, hardenability a grindability; Pono e loaʻa i kahi liʻiliʻi liʻiliʻi i ka oxidation, decarburization a me ka quenching deformation a me ka haki.
1, malleability:he haʻahaʻa welake kalaiwa anake kū'ē deformation, maikaʻi plasticity, forging wela laula ua akea, forging māwae māwae anu a me precipitation pūnaewele carbide keʻano haʻahaʻa.
2, kaʻina hana annealing:He ākea ka laulā wela o ka spheroidizing, haʻahaʻa ka paʻakikī annealing a he liʻiliʻi ka laulā fluctuation, kiʻekiʻe ka nui o ka spheroidizing.
3, hiki ke ʻoki ʻoki:nui ʻoki ʻoki, haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, haʻahaʻa haʻahaʻa machining roughness.
4, oxidation, decarburization sensitivity:ʻO ka hoʻomehana wela kiʻekiʻe, hiki ke maikaʻi ke kūpaʻa o ka oxidation, lohi ka wikiwiki decarburization, ʻaʻole pili i ka mea hoʻomehana, liʻiliʻi ka hana o ka pitting tendency.
5, hiki ke paakiki:ma hope o ke kinai ʻana, loaʻa ka paʻakikī o ka ʻili a kiʻekiʻe.
6, hiki ke paakiki:ma hope o ka hoʻopiʻi ʻana, hiki ke loaʻa kahi papa paʻakikī hohonu, a hiki ke hoʻopaʻapaʻa ʻia ka mea hoʻopiʻi me ka hoʻopaʻa haʻahaʻa.
7, kinai ana i ka deformation mawae:liʻiliʻi ka hoʻololi ʻana o ka leo hoʻopaʻa maʻamau, ʻano warping, liʻiliʻi ka distortion, haʻahaʻa ke ʻano deformation maʻamau. He haʻahaʻa haʻahaʻa haʻahaʻa ka hoʻopiʻi maʻamau a ʻaʻole hiki ke hoʻopaʻa i ka wela a me ke ʻano mea hana.
8, hiki ke wili:liʻiliʻi ka poho o ka huila wili, ʻaʻohe palena kuni ka nui o ka wili ʻana, ʻaʻole maʻalahi ka maikaʻi o ka huila wili a me nā kūlana hoʻoluʻu, ʻaʻole maʻalahi ke komo i ka pōʻino a me ka māwae wili.
