1. Okwu mmalite

Ọkwa 10.9 Dacromet hexagon isi bolts na-anọchite anya klaasị adịchaghị mma nke ngwa ike dị elu nke a na-ejikarị na ụgbọ ala, ihe owuwu, ike ikuku, igwe dị arọ na ngwa akụrụngwa. Ihe mgbochi ndị a na-ejikọta njirimara atọ dị oke mkpa: arụmọrụ kachasị elu nke ụlọ 10.9, geometry na-agbanwe agbanwe na nke a pụrụ ịdabere na ya nke isi hexagonal, na nchebe corrosion pụtara ìhè nke Dacromet (zinc-flake) na-ekpuchi.

2. Klas 10.9 - Mechanical Ike

TS EN ISO 898-1 Klas 10.9 nke ihe onwunwe kọwapụtara (ihe eji arụ ọrụ nke ihe nkedo nke carbon steel na alloy steel - Akụkụ 1: bolts, skru na studs). Nhọpụta "10.9" na-egosi ike tensile ọnụ nke 1000 MPa na oke mkpụrụ-na-nkwụsị nke ihe dịka 0.9. A na-arụpụtakarị ihe nkedo ndị a site na nchara alloy agbanyụchara ma na-ekpo ọkụ (dịka, 35CrMo, 42CrMo, ma ọ bụ ígwè boron) ma dabara adaba maka nhazi dị elu yana ngwa ike.

Ihe eji arụ ọrụ igodo (ISO 898-1)

Ngwongwo	Aha aha	Opekempe	Nkeji
Ike tensile Rm	1000	1040	MPa
Ngosipụta nrụgide / ike mpụta Rp0.2	900	940	MPa
Nchegbu n'okpuru ibu ihe mgbochi Sp	830	—	MPa
Elongation mgbe agbajiri agbaji A	—	9	%
Vickers hardness HV	—	320-380	HV
Rockwell hardness HRC	—	32-39	HRC

Tụnyere ihe onwunwe klaasị 8.8, ọkwa 10.9 na-enye ihe dị ka 25–30 % ikike nkwụchi dị elu yana ikike ibu mwekota dị elu nke ukwuu. Nke a na-eme ka ọ bụrụ nhọrọ kachasị amasị maka nkwonkwo dị oke egwu na engines, chassis, nchara arụ ọrụ, na ngwá ọrụ dị arọ ebe a chọrọ mbelata ibu na ịrụ ọrụ dị elu.

3. Hexa Bolts — Imewe na ụkpụrụ

Ihe mkpuchi isi hexagon (nke a na-akpọ hex bolts) bụ ihe nkedo na-eme ka mpụ na-agbawakarị. Isi nke dị n'akụkụ isii na-enye nnyefe torque dị mma na oghere oghere ma ọ bụ oghere oghere ma na-enye ohere ịnweta site n'ọtụtụ akụkụ. Ụkpụrụ abụọ bụ isi mba ụwa na-achịkwa bolts metric hex:

TS EN ISO 4014 / DIN 931 - eri obere akụkụ (gbanye n'okpuru isi)
ISO 4017 / DIN 933 - eri zuru oke

A na-ahọrọ bolts akụkụ akụkụ (ISO 4014) mgbe ụgbọ elu shiee kwesịrị ime ihe na shank na-enweghị eriri maka ike shiee dị elu, ma ọ bụ mgbe achọrọ ogologo njigide. A na-ahọrọ bolts zuru oke maka mgbanwe na mgbe ogologo zuru ezu nwere ike itinye mkpụrụ ma ọ bụ oghere.

Akụkụ ahụkarị (Nha ahọpụtara, ISO 4014 / DIN 931)

Nha aha	Oghere (mm)	Gafere Flat s (mm)	Isi elu k (mm)	Ogologo eriri b ≤125 mm	Nha mgbanaka
M8	1.25	13	5.3	22	13
M10	1.5	16/17	6.4	26	16/17
M12	1.75	18/19	7.5	30	18/19
M16	2.0	24	10.0	38	24
M20	2.5	30	12.5	46	30
M24	3.0	36	15.0	54	36

Cheta na: N'ofe-flats akụkụ nwere ike ịdị iche iche n'etiti ISO na DIN usoro maka ụfọdụ nha (dịka, M10 na M12). Na-enyocha ọkọlọtọ ọdabara maka ngwa ahụ mgbe niile. Nrịgo ngwaahịa A na B na-akọwa oke ndidi; Ọkwa A bụ nke siri ike ma na-ejikarị ya eme obere dayameta.

4. Ihe mkpuchi Dacromet - Nchekwa Corrosion dị elu

Dacromet bụ teknụzụ mkpuchi nke zinc-flake (nke Metal Coatings International mepụtara na mbụ). Ọ nwere zinc na flakes aluminom kwụsịtụrụ n'ime ihe nkedo inorganic, nke etinyere ya site n'ụzọ dip-spin ma ọ bụ ịgba ma gwọọ ya na ihe dịka 300-340 Celsius. Ihe na-esi na ya pụta dị gịrịgịrị, nnukwu, ọlaọcha-acha ntụ ntụ na-enye nchebe corrosion multi-mechanism na-enweghị ihe ize ndụ nke hydrogen embrittlement - uru dị oke mkpa maka ihe nkedo dị elu dị ka ọkwa 10.9 na 12.9.

Njirimara arụmọrụ igodo

Oke	Ọnụ ahịa/arụmọrụ nkịtị
mkpuchi mkpuchi	5 - 15 μm (Ọkwa A ≈ 5 μm; Ọkwa B ≈ 8 μm)
Mgbasa nnu na-anọpụ iche (ASTM B117)	500 - 1000+ awa na-acha uhie uhie nchara (dabere na ọkwa)
Nguzogide okpomọkụ	Ruo 300 Celsius C na-aga n'ihu (ihe mkpuchi na-anọgide na-echebe)
Ihe egwu embrittlement hydrogen	Ọ dịghị (usoro na-abụghị electrolytic, enweghị acid pickling)
Ọnụọgụ nke esemokwu	0.12 - 0.18 (ya na ụdị mmanu dị ka Dacromet 500)
Ọdịdị	Ọla ọcha ọla-acha ntụ ntụ; mkpuchi uwe ọbụna na eri

Tụnyere na mkpuchi mkpuchi ọzọ a na-ahụkarị

Njirimara	Electro Zinc	Galvanizing na-ekpo ọkụ	Dacromet
Ọkpụrụkpụ	5-15 μm	40-85 μm	5-15 μm
Nri nnu (nchara na-acha uhie uhie)	72–240 elekere	400-800 h	500–1000+ h
H₂ embrittlement ize ndụ	Elu	Dị ugbu a	Ọ dịghị
Mmetụta dabara adaba	Dị ala	Elu (na-achọkarị oke)	Opekempe
Kwesịrị ekwesị maka 10.9+	Oke	Achọrọ ịkpachara anya	Magburu onwe

N'ihi na usoro Dacromet anaghị agụnye ọgbọ hydrogen nke electrochemical na enweghị ike ịmịnye acid, ọ bụ mkpuchi kachasị mma (ma na-abụkarị iwu) maka ọkwa 10.9 na ihe mkpuchi dị elu na nkọwa ụgbọ ala na nhazi.

5. Ejikọtara uru & ngwa ngwa

Mgbe ike 10.9 Grade, hexagonal head geometry, na mkpuchi Dacromet jikọtara, ihe nkedo na-arụpụta na-enye nguzozi pụtara ìhè nke ịrụ ọrụ igwe, ịdị mma mgbakọ, na ogologo oge na-adịte aka na gburugburu ebe na-emebi emebi.

Uru ndị isi

1.High mwekota ibu ikike - na-enyere ọkụ nkwonkwo aghụghọ na elu pụrụ ịdabere n'okpuru vibration na ike ibu ibu.

2.Superior corrosion eguzogide - nnu-ịgba arụmọrụ tere aka ot zinc plating mgbe na-echekwa eri ziri ezi.

3.Hydrogen-embrittlement free - ihe nchekwa dị mkpa maka ihe nchara ígwè dị elu.

4.Controlled esemokwu - lubricated Dacromet variants na-enye amụma amụma mmekọrịta torque-tension, na-eme ka mgbakọ na-agbanwe agbanwe.

5.Thermal kwụsie ike - na-anọgide na-echebe na elu okpomọkụ zutere na engine compartments na ulo oru akụrụngwa.

Ogbe ngwa a na-ahụkarị

Automotive: chassis, nkwusioru, igwe mounted, powertrain components
Ike ikuku: flanges ụlọ elu, ihe owuwu nacelle, arịlịka ntọala
Ihe owuwu siri ike & akụrụngwa: àkwà mmiri igwe, ụlọ elu nnyefe, okporo ụzọ ụgbọ oloko
Igwe ugbo na ihe owuwu na-arụ ọrụ n'èzí
Akụrụngwa mmiri na nke dị n'ụsọ osimiri (nwere nhọrọ ọkwa kwesịrị ekwesị)

6. Nkwubi okwu

Ọkwa 10.9 Dacromet hexagon isi bolts na-ebunye ngwakọta a pụrụ ịdabere na ya nke ike tensile dị elu, geometry nrụnye bara uru, yana nchebe corrosion ogologo oge. Site na imezu ihe achọrọ siri ike nke klaasị ISO 898-1 Klas 10.9, na-agbaso ụkpụrụ ọkọlọtọ dị ka ISO 4014, yana iji mkpuchi zinc flake na-enweghị hydrogen, ihe nkedo ndị a na-enye ndị injinia ihe ngwọta pụtara ìhè maka nkwonkwo dị egwu kpughere ma nrụgide arụ ọrụ na gburugburu ebe ike ike.

Nke gara aga. Na-esote.
