AISI 8620 kila

AISI 8620 kilaʻO ia ka nickel alloy haʻahaʻa, chromium, molybdenum case hardening steel, maʻamau i hoʻolako ʻia i loko o ke ʻano i ʻōwili ʻia me ka ʻoi loa o ka paʻakikī max HB 255. Hoʻolako pinepine ʻia ia ma 8620 pahu pōʻai.

Hiki ke maʻalahi i ka wā o ka hoʻomaʻamaʻa paʻakikī, no laila e hiki ai i ka hoʻomaikaʻi ʻana i nā waiwai case/core. Hiki i ka 8620 ke ho'opa'a 'ia ma mua o ka ho'opa'a 'ia 'ana a me ka ho'oha'aha'a 'ia e ka nitriding. Akā naʻe, ʻaʻole ia e pane maikaʻi i ka lapalapa a i ʻole ka paʻakikī induction ma muli o kona ʻano kalapona haʻahaʻa.

Ua kūpono ke kila 8620 no nā noi e koi ana i ka hui pū ʻana o ka ʻoʻoleʻa a me ke kūpale ʻaʻahu.

Hāʻawi mākou iā AISI 8620 i ka pahu pōʻai ma ka ʻōwili wela / Q + T / kūlana maʻamau. Loaʻa ke anawaena mai 20mm a 300mm no ka hoʻouna koke ʻana.

1. AISI 8620 Lahui lako kila

8620 Poe Bar: anawaena 8mm – 3000mm
8620 Pā kila: mānoanoa 10mm – 1500mm x laula 200mm – 3000mm
8620 Pahu huinaha: 20mm – 500mm
Loaʻa nā paipu 8620 e kūʻē i kāu noi kikoʻī.
Hoʻopau i ka ʻili: ʻeleʻele, Mīkini Rough, Huli a i ʻole e like me nā koi i hāʻawi ʻia.

3. ʻO ASTM 8620 Nā kila a me nā mea like me nā mea hoʻohui kemika

4. AISI 8620 Mea Mechanical Steel

• 8620 Nā Waiwai Kino:

• 8620 Mea Mechanical Steel

5. Ka hoʻopaʻa ʻana i nā mea hao 8620

Hana ʻia ke kila kila AISI 8620 ma kahi wela hoʻomaka ma kahi o 2250ºF (1230ºC) a hiki i 1700ºF (925ºC.) ma mua o ka hoʻomaʻamaʻa ʻana i ka wela a i ʻole ka carburizing. Hoʻomaʻalili ka ea ma hope o ka hana ʻana.

6. ASTM 8620 kila wela lapaau

• Hoʻopili

Hiki ke hāʻawi ʻia ke kila AISI 8620 i kahi anneal piha e ka wela i ka 820 ℃ - 850 ℃, a paʻa a paʻa ka mahana ma ka ʻāpana a maloʻo i ka umu a i ʻole ka ea.

• ʻO ka hoʻohenehene

Hana ʻia ka hoʻomaʻamaʻa ʻana i ka wela a me nā ʻāpana i hoʻopau ʻia i ka wai o 8620 steels (ʻaʻole carburized) ma 400 F a 1300 F no ka hoʻomaikaʻi ʻana i ka paʻakikī o ka hihia me ka liʻiliʻi o kona paʻakikī. E hōʻemi ana kēia i ka hiki ke wili i nā māwae.

• Paʻakiki

ʻO ka AISI kila 8620 e austenitized ma kahi o 840 ° C - 870 ° C, a hoʻopau ʻia ka ʻaila a i ʻole ka wai ma muli o ka nui o ka ʻāpana a me ka paʻakikī. Pono i ka ea a i ʻole ka ʻaila.

• Hoʻoponopono maʻamau

1675ºF (910ºC) a me ka ea anuanu. ʻO kēia kahi ala ʻē aʻe e hoʻomaikaʻi ai i ka mīkini ma 8620 mea; Hiki ke hoʻohana ʻia ka normalizing ma mua o ka hoʻopaʻa ʻana i ka hihia.

7. Mīkini o SAE 8620 Steel

ʻO ke kila kila 8620 ka mīkini maʻalahi ma hope o ka mālama ʻana i ka wela a me ka / a i ʻole carburizing, pono i ka liʻiliʻi i ʻole e hōʻino i ka hihia paʻakikī o ka ʻāpana. Hiki ke hana ʻia ka mīkini ma nā ʻano hana maʻamau ma mua o ka mālama ʻana i ka wela - ma hope o ka hoʻomaʻamaʻa ʻana i ka carburizing machining i kaupalena ʻia i ka wili.

8. Welina o 8620 Mea Hana

Hiki ke wiliwili ʻia ka alloy 8620 e like me ke ʻano o ka ʻōwili ʻia e nā ʻano maʻamau, maʻamau ka wili kinoea a i ʻole arc. ʻO ka hoʻomaʻamaʻa mua ʻana ma 400 F he mea maikaʻi a ʻōlelo ʻia ka hoʻomehana ʻana ma hope o ke kuʻi ʻana - e ʻimi i ke kaʻina hana weld i ʻae ʻia no ke ʻano i hoʻohana ʻia. Eia naʻe, ʻaʻole ʻōlelo ʻia ka wili ʻana i ka hihia i hoʻopaʻa ʻia a i ʻole ma ke kūlana paʻakikī

9. Ke noi o ASTM 8620 Steel

Hoʻohana nui ʻia nā mea kila AISI 8620 e nā ʻāpana ʻoihana āpau no nā ʻāpana māmā a me nā kumu e koi ana i ke kūpaʻa ʻana o ka ʻili me ka ikaika kumu kūpono a me nā waiwai hopena.

ʻO nā mea hoʻohana maʻamau: Arbors, Bearings, Bushings, Cam Shafts, Differential Pinions, Guide Pins, King Pins, Pistons Pins, Gears, Splined Shafts, Ratchets, Sleeves a me nā noi ʻē aʻe kahi e kōkua ai ka loaʻa ʻana o ke kila hiki ke hana maʻalahi a carburized i ka hohonu o ka pahu pahu.
