Loaʻa i kahi mea paahana kūpono no ka hana, a ʻoi aku ka nui ma mua o ka ʻole, pono ia i ke kila kūpono e hana ai i kēlā mea hana.ʻO A2 ka pae maʻamau o ka pahu kila i hoʻohana ʻia no ka hana ʻana i nā mea hana no ka hana ʻana i ka metala, lāʻau, a me nā mea ʻē aʻe.ʻO A2 medium-carbon chromium alloy steel he lālā ia o ka hui kila mea hana anu, i koho ʻia e ka American Iron and Steel Institute (AISI), e komo pū ana me O1 haʻahaʻa-carbon kila, A2 kila a me D2 kiʻekiʻe-carbon kiʻekiʻe-chromium kila.

He koho maikaʻi ke kila mea hana anu no nā ʻāpana e koi ana i ke kaulike o ka pale ʻana a me ka paʻakikī.Hana maikaʻi lākou no nā ʻāpana e pono ai ka liʻiliʻi o ka emi ʻana a i ʻole ka distortion i ka wā o ka paʻakikī.

ʻO ke kūpaʻa ʻaʻahu o ke kila A2 ma waena o ke kila O1 a me D2, a he maikaʻi kona ʻano machining a me ka wili ʻana.ʻOi aku ka paʻakikī o A2 ma mua o ke kila D2, a ʻoi aku ka maikaʻi o ka mana ma hope o ka mālama wela ma mua o ke kila O1.

Ma kahi huaʻōlelo, hōʻike ke kila A2 i kahi kaulike maikaʻi ma waena o ke kumukūʻai a me nā ʻano kino, a manaʻo pinepine ʻia he kumu nui, ke kila honua.

Huina

ʻO ke kila A2 ka mea maʻamau i hoʻohana ʻia o nā hui A i helu ʻia ma ka maʻamau ASTM A682, i koho ʻia ʻo "A" no ka paʻakikī o ka ea.

I ka wā o ke kaʻina hana wela, ʻo ka maʻiʻo kalapona ma kahi o 1% e hiki ai i ke kila A2 ke hoʻomohala i ka paʻakikī piha ma o ka hoʻoluʻu ʻana i ka ea mālie - ka mea e pale ai i ka distortion a me ka pohā i hiki ke hana ʻia e ka hoʻopau ʻana i ka wai.

ʻO ka maʻiʻo chromium kiʻekiʻe (5%) o ke kila A2, me ka manganese a me ka molybdenum, hiki iā ia ke hoʻokō i ka paʻakikī piha o 57-62 HRC i nā ʻāpana mānoanoa (4 iniha ke anawaena) - hāʻawi iā ia i ke kūpaʻa dimensional maikaʻi no nā ʻāpana nui.

Nā noi

Loaʻa ka pahu kila A2 ma nā ʻano like ʻole, me ka huinahā, ka poepoe, a me ka palahalaha.Hiki ke hoʻohana ʻia kēia mea hoʻohana no nā ʻano mea hana like ʻole e pono ai ke pale ʻana i ka ʻaʻahu, e like me nā hāmare ʻoihana, nā pahi, nā ʻoki, nā kuʻi, nā mea paʻa, a me nā mea hana ʻoki lāʻau.

No nā mea hoʻokomo a me nā lau, ʻaʻole ʻo ke kila A2 i ka ʻoki ʻana i mea e lōʻihi ai ka lōʻihi, ʻoi aku ka maikaʻi o ke koho ʻana ma mua o ke kila D2 ʻano kiʻekiʻe.

Hoʻohana pinepine ʻia no ka blanking a me ka hana ʻana i ka thread roller make, stamping dies, trimming dies, injection mold dies, mandrels, molds, and spindles.

ʻO Shanghai Histar Metalhāʻawi i ka pahu kila mea hana A2 ma ka huinahā, pālahalaha a poepoe i nā ʻano nui.E kelepona mai iā mākou no ka ʻōlelo a i ʻole e kipa i kā mākou pūnaewele.
