ʻO 3Cr13 kahi mea kila kila maʻamau i hoʻohana nui ʻia i ka hana ʻana i nā ʻāpana mea hana. ʻO kēia kila he kila kila martensitic i loaʻa ka 0.3% carbon a me 13% chromium, a he nui nā waiwai kūpono no ka hana ʻana i nā pahi.
ʻO ke kila 3Cr13 maikaʻi ka pale ʻana i ka corrosion a hiki ke pale aku i ka ʻinoʻino o ka hapa nui o nā kemika, e ʻae iā ia e mālama i kahi kūlana maikaʻi o ka ʻili a hiki i kahi wahi haʻahaʻa. I ka manawa like, ma hope o ka hoʻomaʻamaʻa wela, hiki i ka 3Cr13 kila ke loaʻa ka paʻakikī kiʻekiʻe a me ka paʻakikī, no laila e loaʻa ai ka hana ʻoki maikaʻi a me ke kūpaʻa ʻana. Hana kēia mau hiʻohiʻona i ke kila 3Cr13 i koho kūpono no ka hana ʻana i nā mea ikaika kiʻekiʻe e like me nā pahi, nā lau, a pēlā aku.
Ma keʻano laulā, ua hoʻohana nui ʻia ke kila 3Cr13 i ka mākeke ma muli o kāna hana maikaʻi loa a me ke kumukūʻai kūpono.
Loaʻa i nā mea 5Cr15MoV kahi kūpaʻa kiʻekiʻe, ʻo ia ka mea ma muli o kāna ʻano hoʻohui kemika maikaʻi loa a me ke kaʻina hana wela. ʻO ka paʻakikī o 5Cr15MoV e pili ana iā HRC58-60. ʻO kāna mau kalapona kiʻekiʻe e hoʻomaikaʻi nui i ka paʻakikī o ka mea hana, ʻoiai ʻo nā mea metala o chromium, molybdenum a me vanadium he mau waiwai kūikawā maikaʻi no ka pale ʻana i ka corrosion, ke kūpaʻa a me ka paʻakikī o ka mea hana.
ʻO ka mea kikoʻī, ʻoi aku ka ikaika o ka hāʻawi ʻana, ka ikaika tensile, elongation a me ka paʻakikī o ka hopena o 5Cr15MoV ma mua o 20% kiʻekiʻe ma mua o nā mea kila kila maʻamau, kahi e hana maikaʻi ai i ke ʻano o ke kaomi ʻana, ke kūpaʻa tensile, ka deformation a me ke kūpaʻa hopena. I ka manawa like, loaʻa ka waiwai i ka forgeability a me ka plasticity, a ua maʻalahi ka hana a me ka hana ʻana ma o nā ʻano hana like ʻole, e hoʻomaikaʻi hou ana i kona maʻalahi i ka hana hana.
ʻO nā mea ʻelua i ʻōlelo ʻia ma luna nei ka mea maʻamau i hoʻohana ʻia. Inā loaʻa iā ʻoe nā koi kūikawā a i ʻole nā manaʻo ʻē aʻe, e ʻoluʻolu e nīnau i ka Hui RUITAI, e hāʻawi mākou iā ʻoe i kahi hopena kūpono.
