ʻO nā ʻōleʻa kila kila: nā ʻāpana Hex a me nā pae waiwai

1. Hoʻolauna

Hoʻohui ʻia nā bolts stainless steel i ke kūpaʻa corrosion inherent me ka ikaika mechanical, e hoʻolilo iā lākou i mea koʻikoʻi ma ke kūkulu ʻana, ka moana, ka hana ʻai, a me nā ʻoihana olakino. ʻAʻole like me nā mea hoʻopaʻa kila kalapona e koi ana i nā pale pale, loaʻa ke kila kuhili i kona kūpaʻa ʻana mai kahi papa chromium oxide hoʻōla ponoʻī. Hoʻopili kēia alakaʻi i nā ʻaoʻao koʻikoʻi ʻelua: ka hoʻolālā hex bolt a me ke koho ʻana i ka papa kila kila.

2. Hex Bolts

Hōʻike ʻia nā bolts Hex i kahi poʻo ʻeono ʻaoʻao e hiki ai i ka hoʻololi ʻana i ka torque kūpono ma o nā wrenches maʻamau a i ʻole nā kumu. Aia i loko o ka ho'olālā ke po'o hexagonal, ka māwae 'ole, ka 'āpana milo, a me ka piko chamfered. ʻO nā pōmaikaʻi koʻikoʻi, ʻo ia ka mana kiʻekiʻe torque, hiki i ke ao holoʻokoʻa, hana pono, hoʻohana hou, a me ka hoʻokō ʻana i nā kūlana honua (ISO 4014, DIN 933, ASTM A325).

Papa 1. Nā Nui Hex Bolt (Stainless Steel)

Nui inoa	Loko Loko (TPI)	Laulā poʻo (mm)	Ikaika U'i (MPa)
1/4 - 20	20	11.1	520
3/8 - 16	16	14.3	520
1/2 - 13	13	19.1	520
3/4 - 10	10	28.6	520

3. Nā Papa Kūleʻa

Hoʻokaʻawale ʻia nā mea hoʻopaʻa kila kila i ʻehā ʻohana: austenitic (304, 316 — non-magnetic, high corrosion resistance), ferritic (430 — magnetic, economical), martensitic (410 — hardenable, moderate corrosion), a me ka ua-hardening (17-4PH — ikaika kiʻekiʻe). Ma lalo o ISO 3506, hoʻohana nā māka i ka helu helu leka kahi A = austenitic, C = martensitic, a ʻo ka helu e hōʻike ana i ka papa ikaika tensile (50/70/80).

Papa 2. Nā Papa Kūleʻa Kūleʻa maʻamau no nā Bolts

Papa	Papa ISO	U'a (MPa)	Pale ʻino.	Nā Mea Koʻikoʻi	Hoʻohana maʻamau
304	A2-70	700	Maikaʻi	18% Cr, 8% Ni	Ke kumu nui, meaʻai
316	A4-70	700	Maikaʻi	16% Cr, 10% Ni, 2% Mo	Ke kai, kemika, ka lāʻau lapaʻau
410	C3-80	550	Kaumaha	12% Cr	Mea ʻokiʻoki, valves
17-4PH	A4-80	800	Maikaʻi	16% Cr, 4% Ni, 4% Cu	Aerospace, kiʻekiʻe-ikaika

3.1 Koho ʻana ma ka Kaiapuni

Papa 3. Nā Papa i Manaʻo ʻia e ka Environment Service

Kaiapuni	Papa Manaʻo	Ke kumu
Loko / Maloo	304 (A2)	Kūpono ma ke kumu kūʻai haʻahaʻa
Ma waho / kahakai	316 (A4)	Kūʻē ʻo Mo i ka hoʻouka kaua chloride
Mea Hana Kemika	316L / 904L	ʻOi aku ka pale ʻana i ka waika
Pono kiʻekiʻe ikaika	17-4PH (A4-80)	Ua paʻakikī ka ua

ʻO nā Bolts Hex Bolts a me nā pae waiwai

4. Nā Manaʻo Nui

Galling: Hiki i nā māka Austenitic (304, 316) ke hopu i ke kaula i ka wā o ka hoʻopaʻa ʻana. E hoʻohana i nā pūhui anti-seize a i ʻole nā hui like ʻole (A2 bolt me A4 nut) e hoʻēmi.

Ka hoʻopaʻapaʻa: Hoʻopau ka hoʻomaʻamaʻa Acid (ASTM A967) i ka hao manuahi a hoʻonui i ka papa oxide, hoʻomaikaʻi i ka pale ʻana i ka corrosion ma hope o ka hana ʻana.

Mākēneki: ʻAʻole magnetic nā māka Austenitic ke hoʻopili ʻia akā hiki ke lilo i ʻāpana magnetic ma hope o ka hana anu. ʻO nā māka Ferritic a me ka martensitic he mea magnetic.

5. Ka hopena

Hoʻohui nā bolts hex kila kila i ka hoʻolālā geometric kūpono me ka versatility metallurgical. Mai ka papa waiwai 304 no ka hoʻohana maʻamau a hiki i ka 17-4PH ikaika kiʻekiʻe no nā noi koi, ʻo ka hoʻohālikelike ʻana i ka māka kūpono i ke kaiapuni lawelawe e hōʻoia i ka hana maikaʻi loa a me ka lōʻihi.

ʻAʻole Loaʻa. Aʻe.
