Papa 8.8, 10.9 & 12.9 Nā Bolts a me nā Screws: Manaʻo ʻia nā mea waiwai no nā mea paʻa ikaika kiʻekiʻe. 

Hoʻomaʻamaʻa wela a me nā noi

Quenching & Tempering (Q&T). Ka laulā oolea maʻamau: 22–32 HRC. Nā mea hoʻohana: nā pilina kila, nā chassis kaʻa, nā mīkini maʻamau, nā hui flanged, nā pilina lāʻau-a- kila.

Papa 10.9 Bolts & Screws — Ikaika Kiekie

Hāʻawi ka papa 10.9 bolts a me nā wili i ka ikaika tensile haʻahaʻa o 1,040 MPa. Hōʻike ʻia lākou ma nā wahi āpau e koi ʻia ai nā pilina paʻa, kiʻekiʻe-clamping-ikaika - mai nā ʻenekini kaʻa a hiki i nā mea hoʻoneʻe honua. ʻO nā ʻano huahana maʻamau, ʻo ia nā ʻoki poʻo poʻo kumu, nā kī hex flanged, a me nā bolts stud ikaika kiʻekiʻe.

Mea Manaʻo ʻia

• 40Cr Alloy Steel — Lio hana maʻamau no ka Papa 10.9. ʻO ka paʻakikī kaulana, loaʻa ākea, a hōʻoia ʻia i nā koi ISO 898-1.
• 35CrMo Alloy Steel — ʻO ke kila Chromium-molybdenum me ka ʻoi aku ka paʻakikī a me ke kūpaʻa luhi. He mea maʻamau no nā bolts a me nā wili ma lalo o ka hoʻouka ikaika.
• 42CrMo Alloy Steel — ʻOi aku ka nui o ke kalapona ma mua o 35CrMo; hāʻawi maikaʻi i ke kaulike ikaika-ʻoʻoleʻa no ka nui-diameter Grade 10.9 hex bolts.
• SCM435 (JIS) — ʻO ke kūlana ʻoihana Iapana e like me 35CrMo. Hoʻohana nui ʻia i nā kaulahao hoʻolako paʻa paʻa ma Asia-Pacific; kūlana kūlike maikaʻi loa.

Hoʻomaʻamaʻa wela a me nā noi

Quenching & Tempering (Q&T). Ka laulā oolea maʻamau: 32–39 HRC. Nā mea hoʻohana: nā kī hoʻopaʻa ʻenehana, ka hoʻokuʻu ʻana a me nā mea hoʻopaʻa hoʻokele kaʻa, nā bolts wind-turbine tower bolts, nā pilina pili kino.

Papa 12.9 Bolts & Screws — Ka ikaika kiʻekiʻe loa

ʻO ka papa 12.9 ka papa waiwai kūlana kiʻekiʻe loa no nā mea hoʻopaʻa metric (ʻoi loa ka ikaika tensile 1,220 MPa). ʻO ka ikaika kiʻekiʻe kiʻekiʻe e koi ana i ke kila kila kila me ka kemika hoʻomalu paʻa. Hoʻohana ʻia kēia mau mea hoʻopaʻa - ʻo nā ʻoki poʻo poʻo kumu nui a me nā bolts ʻoihana kūikawā - ma nā wahi āpau ʻaʻole hiki ke kūkākūkā ʻia nā palena palekana a me ke ola luhi.

Mea Manaʻo ʻia

• 42CrMo4 / 42CrMo Alloy Steel — ʻO ke koho maʻamau honua no ka Papa 12.9. ʻO ka paʻakikī maikaʻi loa, ka ikaika luhi kiʻekiʻe, ka hāʻawi like ʻana o ka paʻakikī (39-44 HRC ma hope o ka Q&T). Hoʻokō me ISO 898-1, DIN EN 10263, a me nā alakaʻi alakaʻi ASTM.
• SCM440 (JIS) — Ua like ka Iapana me 42CrMo4. Nui i ka hana ʻana ma Asia Hikina; ʻoi aku ka maikaʻi o ka hoʻopau ʻana i ka ʻili a me ka hoʻomanawanui ʻana no nā wili pāpale socket.
• 35CrMoV Alloy Steel — Hoʻonui ʻia ʻo Vanadium no ka hoʻomaikaʻi ʻana i ka pale ʻana a me ka ikaika kolo. Koho ʻia no nā noi hoʻopaʻa haʻahaʻa kiʻekiʻe a i ʻole kiʻekiʻe-vibration.
• 30CrNiMo8 Alloy Steel — ʻO ke kila Nickel-chromium-molybdenum no nā kūlana hoʻouka nui. Hoʻokaʻawale ʻia no nā bolts aerospace-e pili ana a koʻikoʻi.

Hoʻomaʻamaʻa wela a me nā noi

Quenching & Tempering (Q&T) me ka mana paakiki (39–44 HRC). Nā noi: nā ʻūhā caliper disc brake, nā mea hana mīkini pololei, nā heleuma hoʻolālā koʻikoʻi, nā ʻoki poʻo poʻo poʻo (DIN 912 / ISO 4762), nā mea hoʻopaʻa ʻoihana kūikawā.

E pili ana i Fujirui Metal — Mea Hana Hoʻopaʻa Paʻa ʻOihana & Mea Hoʻopuka

Hana a hoʻokuʻu aku ʻo Fujirui Metal i nā mea hoʻopaʻa pololei e pili ana i nā bolts ikaika kiʻekiʻe, nā wili hex, nā wili hoʻoheheʻe ponoʻī, nā bolts stud, a me nā studs ʻelua ma waena o ka Papa 8.8, 10.9, a me 12.9. Nā koho lapaʻau ʻili: Dacromet, Ruspert, hot-dip galvanising, a me ka zinc plating. Hoʻopaʻa ʻia nā huahana āpau i nā kūlana ISO, DIN, a me ASTM, me nā palapala hōʻoia hōʻoia piha piha (MTC) i loaʻa.
