ʻO 20CrNiMo ka helu kila mua 8620 ma nā kūlana AISI a me SAE ʻAmelika.ʻO ka hana paʻakikī e like me ke kila 20CrNi.ʻOiai ʻo ka Ni maʻiʻo i loko o ke kila he hapalua ia o 20CrNi kila, ma muli o ka hoʻohui ʻana i kahi mea liʻiliʻi o ka mea Mo, ʻo ka ʻaoʻao luna o ka austenite isothermal transformation curve e neʻe i ka ʻākau;a ma muli o ka hoʻonui kūpono o ka Mn maʻiʻo, ʻoi aku ka maikaʻi o ka paʻakikī o kēia kila, a ʻo ka ikaika ʻoi aku ka kiʻekiʻe ma mua o ke kila 20CrNi, a hiki ke hoʻololi i ke kila 12CrNi3 e hana i nā ʻāpana carburized a me nā ʻāpana cyanide e koi ana i ka hana kumu kiʻekiʻe.Hiki i ka 20CrNiMo ke pale aku i kekahi mahana ma waho aʻe o nā waiwai piha maikaʻi no ka mea aia ka molybdenum.
1. Ma kaʻoihana hana, hoʻohana pinepineʻia e hana i nā'āpana e pili ana i ka ukana kiʻekiʻe, ke kaumaha kiʻekiʻe, a me kaʻaʻahu kiʻekiʻe, e like me ke kāhili, nā pahu, nā bearings, etc. ʻO ko lākou ikaika kiʻekiʻe a me ka paʻakikī maikaʻi e hiki ai i kēia mau māhele ke mālama i kahi ola lōʻihi ma nā wahi hana paʻakikī.Eia kekahi, loaʻa iā ia ke kūpaʻa luhi maikaʻi a me ka pale ʻana i ka corrosion, hiki ke pale maikaʻi i ka erosion o ke kaiapuni waho a hōʻoia i ka hana paʻa o nā mea hana.
2. Ma ke kahua o ka hana, hoʻohana nui ʻia kēia kila i ka hana ʻana i nā hale nui e like me nā alahaka a me nā hale kiʻekiʻe ma muli o kona ikaika kiʻekiʻe a me ka ductility maikaʻi.I loko o kēia mau hale, hiki iā lākou ke kū i ke koʻikoʻi nui a me ka haʻalulu, e hōʻoia ana i ka palekana a me ka paʻa o ka hale.
3. Eia kekahi, me ka hoʻomaikaʻi ʻana i ka ʻike kaiapuni, ʻoi aku ka nui o nā noi ma ke kahua o ka mālama ʻana i ke kaiapuni.No ka laʻana, i nā kaʻa ikehu hou, hiki ke hoʻohana ʻia e hana i nā mea koʻikoʻi e like me nā kaʻa a me nā mea hoʻemi, e hāʻawi ana i ka huakaʻi ʻōmaʻomaʻo.He kuleana koʻikoʻi nō hoʻi ia i nā lako palekana kaiapuni e like me ka mālama ʻana i ka wai a me ka mālama ʻana i nā kinoea, e hāʻawi ana i ke kākoʻo ikaika no ka hoʻomaikaʻi ʻana i ka maikaʻi o ke kaiapuni.
1. ʻO nā mea hana koʻikoʻi, e like me nā mea hoʻokele mokulele, nā pahu pahu a me nā ʻāpana kaʻa kaua.
2. Nā mea hoʻopaʻa ikaika kiʻekiʻe a me nā mea hoʻohui.
3. ʻO nā haʻahaʻa haʻahaʻa kiʻekiʻe a me nā bearings.
Hoʻopau i ka 850ºC, aila anu;Ka wela 200ºC, hoʻoluʻu ea.
ʻO ka lawe ʻana i ka mālama ʻana i ka wela (normalizing, annealing a i ʻole ka wela wela kiʻekiʻe) a i ʻole ke kūlana mālama wela, e hōʻike ʻia ke ʻano o ka lawe ʻana i ka ʻaelike.
Ke kākoʻo ʻia nei e kahi pūʻulu hoʻomohala a loea, hiki iā mākou ke hāʻawi i ke kākoʻo ʻenehana ma mua o ke kūʻai aku a me ka lawelawe ma hope o ke kūʻai aku.
