6. Matchlitional a me ka hanaʻana o 4140 Kukui Kekuhi
Markinpalibility
Waiwai 4140 Ke hōʻike neiʻo Steel i ka Manchite i ka inoa inoa inoa i loko o kona moku'āina a lilo i paʻakikī e like me ka paʻakikī e hoʻonui.
I ke kūlana Anneed (maʻamau ma kahi o 18-22 HRC), Hiki ke mactid me nā kiʻi kila kiʻekiʻe a iʻole nā mea hana kaʻa kaʻa, ʻO ka hāʻawiʻana i nā mea maikaʻi maikaʻi e hoʻopau i ke ola kūpono.
Akā naʻe,, I ka wā e pau ai ka steel i ka hanaʻana i nā pae paʻakikī kiʻekiʻe (e like me 30-50 hrc), ua ho'ēmiʻia kona mach.
I kēia hana, mea hoʻoili lāʻau kaʻaʻula, nā wikiwiki haʻahaʻa haʻahaʻa, a me nā hoʻonohonoho mīkini rigid e lilo i mea pono e pale i ka hana e hoʻohana ai a me ka hoʻokaʻawaleʻana.
No ka Cnc huli, MilightʻAʻole, a iʻole nā hana hana, Ke hoʻohana nei i nā hana maʻalahi kūpono e kōkua ai i ka collad cheolant-kōkua i ka wela wela a hoʻomaikaʻi i ka haʻaleleʻana i ka chip.
Hōʻemi lima 4140 Pono pinepine nā'āpana i ka COBALT a iʻole nā mea hana kaʻa kaʻa, ʻOiai e hoʻomauʻia nā'āpana paʻakikī i ka loaʻaʻana mai ka heluʻana i ke aniani a iʻole e hana ana i nā taps ma mua o nā kaulaʻokiʻoki.
Welding
Welding 4140 Pono ke kila ma muli o kona mau paʻakikī kiʻekiʻe a me ka pilikia o ka cracking.
E hoʻomaʻamaʻa i kēia mau pilikia, ka hoʻomaʻamaʻaʻana i ka hana hana-maʻamau ma 200-400 ° C ma muli o ka mānoanoa i hoʻopaʻaʻia.
Ke mālama nei i kahi mahana o kaʻoihana ma kahi o 200-300 ° C e kōkua i ka paleʻana i ka pīhoihoi a me ka hydrogen.
Ma hope o ka welding, kaumaha-e hōʻoluʻolu i ka māhele ma kahi o 600-650 ° C ell rent.
ʻO nā mea uila haʻahaʻa-hydrogen e like me e8018-b2 a iʻole err80s-d2 i hoʻohana pinepineʻia no ka hoʻololiʻana a hōʻemi i ka hoʻohālikelike.
Ma nā noi koʻikoʻi, ʻO ka hana wela wela (Pwht) pono e mālama i ka integrity a paʻakikī o ka wahi i welded.
Anuanu a me keʻano wela
4140 Hiki i ke alallol ke ala i hanaʻia ma kona kūlana anneed, ʻOiaiʻo kona ikaika kiʻekiʻe i hoʻohālikelikeʻia i nā pahu haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa i kona mau distility.
Nā kaʻina hana hoʻohālikelike e like me ke kiʻiʻana a me ke kiʻiʻana a hiki ke koi aku akā e koi ai i nā koina kiʻekiʻe.
Ka hana wela, me ke kalaʻana a me ka wela wela, ʻoi aku ka maikaʻi no ka kila 4140.
ʻO ke kala kala kūpono loa ma waena o 900 ° C a me 1200 ° C, Me ka mea maʻamau e hoʻopau pinepineʻia ma luna o 850 ° C.
Ma hope o ke kau wela, ʻO ka hana maʻamau a iʻole kaʻaeʻana e hōʻoiaʻia e hoʻoponopono i keʻano grain a hoʻomākaukau i ka kila no ka maching hope a iʻole ka mālama wela.
