ʻOi aku ka maikaʻi o ke kila mea hana A2 ma mua o ke kila mea hana D2

He mea nui ka kila kila i ka holomua o ka mīkini pololei, ke kuʻi metala, ka hana make, a me ka nui o nā noi ʻoihana. Ma waena o nā ʻano kila mea hana i loaʻa,A2aD2ʻelua o nā mea maʻamau i hoʻohana ʻia. ʻO nā mea ʻenehana, nā loea kūʻai, a me nā mea hoʻolālā mea hana pinepine i ka nīnau:
Ua ʻoi aku ka maikaʻi o ke kila mea hana A2 ma mua o ke kila mea hana D2?

Aia ka pane i ka noi kikoʻī, nā koi waiwai, a me nā manaʻolana hana. Ma kēia ʻatikala, e hoʻohālikelike mākou i nā kila mea hana A2 a me D2 ma waena o ka haku mele ʻana, ka paʻakikī, ka paʻakikī, ke kūpaʻa ʻana, ka machinability, a me ka hoʻohana ʻana i nā hihia e kōkua iā ʻoe e hoʻoholo i ka mea i kūpono i kāu mau pono.

Nānā nui o A2 Mea Hana kila

A2 mea kilahe kila hoʻopaʻakikī paʻakikī ea. Aia ia i ka A-series (air-hardening) a ua ʻike ʻia no ke kaulike maikaʻi ma waenaʻaʻahu kūʻēaʻoʻoleʻa.

Nā waiwai nui o A2:

  • ʻOi aku ka paʻa ʻana o ka dimensional i ka wā mālama wela

  • Machinability maikaʻi

  • ʻAʻahu kū mālie

  • ʻO ka paʻakikī hopena kiʻekiʻe

  • Hoʻopaʻa maʻamau i 57-62 HRC

  • Kū'ē i ka māhā a me ka distortion

Nā noi maʻamau:

  • ʻO ka blanking a me ka hana ʻana i make

  • Make ʻo Trim

  • Make ka ʻōwili kaula

  • Nā ana

  • Nā pahi ʻoihana

Nānā nui o D2 Tool Steel

D2 mea hao kilahe kalapona kiʻekiʻe, kiʻekiʻe chromium kiʻekiʻe anu hana kila kila kaulana no konamaikaʻi maikaʻi ke pale ʻana i ka ʻaʻahuapaakiki kiekie. Aia ia i ka D-series (ke kalapona kiʻekiʻe, nā kila chromium kiʻekiʻe), a hoʻohana nui ʻia i nā noi kahi e kau ʻia ai nā mea hana i ka lole abrasive.

Nā waiwai nui o D2:

  • Kūleʻa kiʻekiʻe loa i ka ʻaʻahu

  • ʻO ka paʻakikī kiʻekiʻe, maʻamau 58-64 HRC

  • Ka ikaika compressive maikaʻi

  • ʻOi aku ka paʻakikī o ka hopena ma mua o A2

  • ʻO ka ʻaila a i ʻole ka ea paʻakikī

Nā noi maʻamau:

  • Kuʻi a make

  • ʻAhi ʻāhi

  • Nā mea hana ʻoki ʻoihana

  • ʻO nā momi palaki

  • ʻO nā mea hana kālā a me ka embossing

Mai kēia pakuhi, hiki iā mākou ke ʻike i kēlāʻOi aku ka nui o ke kalapona a me ka chromium iā D2, e hā'awi ana i ke kū'ē a me ka pa'akikī. Eia naʻe,ʻOi aku ka paʻakikī o A2ma muli o ka ʻoi aku o ke kaulike o nā mea hao.

Paʻa Paʻa a Wear

  • D2: ʻIke ʻia no nā pae paʻakikī a hiki i ka 64 HRC, no laila kūpono ia no nā hana ʻaʻahu. Mālama ʻo ia i ka ʻoi o ka maka no ka manawa lōʻihi.

  • A2: He palupalu iki ma kahi o 60 HRC, akā ua lawa ka pale ʻaʻahu no nā noi maʻamau.

Ka hopena: D2 maikai nokūʻē abrasion, ʻoiai ʻoi aku ka maikaʻi o A2 no nā mea paahana e pili ana ihoʻouka haʻalulu.

ʻO ka ʻoʻoleʻa a me ka pale ʻana i ka hopena

  • A2: ʻOi aku ka ikaika o ka hopena a me ka ʻoi aku ka paʻakikī, e kōkua i ka pale ʻana i ka haki ʻana a i ʻole ka ʻoki ʻana i ka wā o ka hana.

  • D2: ʻOi aʻe ka palupalu i ka hoʻohālikelike ʻana; ʻaʻole kūpono no ka hopena a i ʻole nā kūlana haʻahaʻa kaumaha.

Ka hopena: ʻOi aku ka maikaʻi o A2 no nā noi e koi anaka ikaika hopena a me ke kū'ē i ka haki.

Paʻa Manaʻo i ka wā o ka mālama ʻana i ka wela

Hōʻike nā kila ʻelua i ke kūpaʻa maikaʻi, akā:

  • A2: ʻO ka paʻakikī o ka ea ka mea i kūpaʻa loa; emi iho ka pilikia o ke kaua.

  • D2: ʻOi aku ka maʻalahi i ka hoʻololi iki ʻana ma muli o ke kiʻekiʻe o ka ʻike kalapona a me ka ʻaila / ea kinai.

Ka hopena: A2 maikai iki nomea paahana pololei.

Mīkini

  • A2: ʻOi aku ka maʻalahi o ka mīkini i ke kūlana annealed ma muli o ka haʻahaʻa o ka carbide maʻiʻo.

  • D2: Paʻakikī i ka mīkini ma muli o ke kūpaʻa ʻaʻahu kiʻekiʻe a me ka paʻakikī.

Ka hopena: ʻOi aku ka maikaʻi o A2 inā pono ʻoehana maʻalahia i ʻole ke hana nei me nā ʻano paʻakikī.

Paʻa ʻana a me ka hana ʻoki ʻana

  • D2: Paʻa i ka maka oi no ka lōʻihi loa; kūpono no nā mea hana ʻoki lōʻihi a me nā pahi.

  • A2: Paʻa ma ka ʻaoʻao kūpono akā pono ka ʻoi pinepine ʻana.

Ka hopena: Ua oi aku ka D2 manā mea hana ʻoki ʻoki.

Noonoo Kumukuai

  • D2: ʻOi aku ke kumu kūʻai ma muli o ke kiʻekiʻe o ka ʻike o ka alloy a me nā koina hana.

  • A2: ʻOi aku ke kumukūʻai a maʻalahi hoʻi e hana pū me nā noi he nui.

Ka hopena: Hāʻawi ʻo A2 i kahi ʻoi aku ka maikaʻikaulike o ka hana a me ka ukuno nā noi maʻamau.

ʻO wai ka mea ʻoi aku ka maikaʻi?

ʻAʻohe pane hoʻokahi. ʻO ka koho ma waena o A2 a me D2 e pili ana i nā waiwai nui loa no kāu papahana.

  • D2kūpono nokuʻi ʻana i nā mea lahilahia i ʻole ke koʻikoʻi ka lōʻihi o ke ola.

Ke kiʻi nei i nā mea kila A2 a me D2

Ke ʻimi nei i kekahi o kēia mau mea kila, he mea nui e hōʻoia i ka maikaʻi kūlike, nā koho mālama wela hilinaʻi, a me ka hōʻoia piha. ʻO kēia kahisakysteelhiki ke kākoʻo i kāu mau pono waiwai.

Ma ke ʻano he mea hoʻolako honua o nā mea kila,sakysteelhāʻawi:
