He kila ʻoleʻa – Papa 431 (UNS S43100)

ʻO nā kila kila kila 431 he martensitic, nā māka wela me ka maikaʻi o ka corrosion resistance, ka ikaika torque, ka paʻakikī kiʻekiʻe a me nā waiwai tensile. ʻO kēia mau waiwai a pau e kūpono iā lākou no nā noi bolt a me shaft. ʻAʻole hiki ke hoʻohana ʻia kēia mau kila ma muli o ko lākou ikaika hua kiʻekiʻe, no laila ua kūpono lākou no nā hana e like me ka wili, kiʻi hohonu, ka piko a i ʻole ke poʻo anu.

Hoʻohana pinepine ʻia ka hana ʻana i nā kila martensitic me ka hoʻohana ʻana i nā ʻenehana e ʻae ai i ka mālama paʻakikī a me ka hoʻomaʻamaʻa ʻana a me ka maikaʻi ʻole o ka weldability. ʻOi aku ka haʻahaʻa o nā waiwai pale corrosion o nā kila 431 ma mua o nā māka austenitic. ʻO nā hana o ka papa 431 ua kaupalena ʻia e ko lākou nalo ʻana o ka ikaika i nā wela kiʻekiʻe, ma muli o ka hoʻoulu ʻana, a me ka nalowale o ka ductility i nā wela maikaʻi ʻole.
