Kalasi 10.9 Blue-White Zinc Hex Bolt DIN 933 | ISO 4017 | Full-Thread Hexagon Bolt yokhala ndi Zinc Electroplating & Blue-White Passivation

2026-07-10

Bawuti ya Grade 10.9 Blue-White Zinc DIN 933 hex imapereka mphamvu yolimba kwambiri (yolimba kwambiri ≥ 1,040 MPa) yokhala ndi zotsika mtengo, zotengera RoHS zokongoletsa komanso zogwira ntchito. Ndiwo chomangira chosankha pamakina a injini zamagalimoto, makina olemera, kulumikizana ndi turbine yamphepo, ndi zitsulo zomangika pomwe ma compact, olimba kwambiri amafunikira.

Giredi 10.9 DIN 933 Hex Bolt yokhala ndi Electroplating ya Blue-White Zinc Finish

Gawo 1 - Kalasi 10.9: Kalasi Yamphamvu Yamphamvu Kwambiri

Giredi 10.9 ndi gulu lachiwiri lapamwamba kwambiri la zomangira ma metric pansi pa ISO 898-1, lomwe likukhala pakati pa Gulu la 8.8 logwiritsidwa ntchito kwambiri ndi Gulu la 12.9 lamphamvu kwambiri. Imakhala ndi mphamvu zochulukirapo, kukhazikika kovomerezeka, komanso kutopa kodziwikiratu, ndikupangitsa kuti ikhale yokhazikika pamalumikizidwe ofunikira kwambiri pamagalimoto, mphamvu, ndi makina olemera.

Property Class Decoding

Nambala yoyamba (10): Imawonetsa 1/100 yamphamvu yocheperako mu MPa → mphamvu yocheperako = 1,000 MPa (yokhazikika pa 1,040 MPa).
Nambala yachiwiri (9): Amasonyeza chiŵerengero cha mphamvu zokolola zosachepera ku mphamvu yocheperako × 10 → chiŵerengero cha zokolola = 0.90, kutanthauza mphamvu zochepa zokolola = 940 MPa.

Zomangira za Grade 10.9 zimapangidwa kuchokera kuzitsulo za alloy - nthawi zambiri 40Cr, 35CrMo, 42CrMo, kapena SCM435 - zomwe zimathandizidwa ndi kutentha ndi kutentha (Q&T). Zomwe zili pamwamba pa kaboni ndi aloyi (Cr, Mo) zimapereka kuuma kofunikira kuti mukwaniritse kulimba kwapakati pa 32-39 HRC kudutsa gawo lonse, ngakhale ma diameter akulu (mpaka M36).

Minda Yofunika Kwambiri

Zagalimoto: Maboti oyika injini, mabawuti olumikizira, zomangira ma flywheel, mabawuti oyimitsira mkono, maulalo owongolera.
Mphamvu yamphepo: Ma flanges a Tower section, ma nacelle structural connections, pitch bear bolts.
Makina akuluakulu: Maboliti ofufutira, zolumikizira chimango cha bulldozer, zomangira mphete za crane.
Kupanga zitsulo: Maulumikizidwe odzaza ndi mikangano (BS EN 14399-3 HR system), misonkhano yokhala ndi mlatho.

Gawo 2 - DIN 933: Full-Thread Hexagon Bolt Standard

DIN 933 imatchula mabawuti ammutu a hexagon okhala ndi ulusi wokulirapo wa metric kuchokera ku M1.6 mpaka M52. Ngakhale idatsitsidwa mwaukadaulo ndi ISO 4017, DIN 933 ikadali muyeso wa bolt womwe umatchulidwa pafupipafupi m'makalata ogula zinthu ku Europe, zojambula zaukadaulo, ndi mabilu azinthu padziko lonse lapansi.

Mawonekedwe Ofunika Kwambiri

Shank ya ulusi wonse: Ulusi umatalikirana ndi utali wonse, kukulitsa kusinthasintha kwa kutalika kwa zingwe ndi kuphweka - gawo limodzi limalowa m'malo mwa mabawuti angapo otalikirana pang'ono.
Mutu wa hexagon: M'lifupi mwake modutsa ma flats (ma) pa DIN EN ISO 272. Kutalika kwamutu mwadzina (k) kumapereka malo okwanira osungiramo makina ochapira wamba ndi chinkhoswe cha socket.
Metric coarse pitch: Malinga ndi ISO 261/ISO 724. Ulusi wokhotakhota umalekerera kuwonongeka kwa pamwamba, suchedwa kuphulika, ndipo umakhala wothamanga kwambiri kusiyana ndi njira zina zomveka bwino.
Gulu la kulolerana: Gulu la mankhwala A kukula kwake ≤ M24 ndi kutalika ≤ 10d kapena ≤ 150 mm; kalasi B yazinthu zazikulu (ISO 4759-1).

DIN 933 Giredi 10.9 Quick Reference

Miyezo yodziwika bwino ya DIN 933 yopanga Giredi 10.9 (M6–M24). Kulemera kwamphamvu kumawerengedwera pamalo ocheperako opsinjika × 1,040 MPa.

Kukula	Kutalika (mm)	s (mm)	k (mm)	Min. Tensile Load (kN)	Utali Wautali
M6	1.00	10	4.0	15.8	10-90 mm
M8	1.25	13	5.3	29.1	16-150 mm
M10	1.50	17	6.4	46.5	20-200 mm
M12	1.75	19	7.5	67.3	20-300 mm
M16	2.00	24	10.0	122	25-300 mm
M20	2.50	30	12.5	191	30-400 mm

s = m'lifupi mwadzina kudutsa ma flats, k = kutalika kwa mutu. Kulemera kwa katundu pa ISO 898-1 malo opanikizika × 1,040 MPa.

Chizindikiro Cholembera

Bawuti iliyonse ya Giredi 10.9 ya DIN 933 imakhala ndi “10.9” m'mutu ndi chizindikiro cha wopanga malinga ndi ISO 898-1. Kutsirizira kwa zinc koyera kwa buluu kumapereka chizindikiritso chaposachedwa komanso kumathandizira kusanja kowongolera.

Gawo 3 - Blue-White Zinc Electroplating

Zinc yoyera ya buluu (Zn/An/Cn/T0 pa ISO 2081, kapena Type II SC 1 pa ASTM B633) ndi zokutira zama electroplated zinki zomwe zatha ndi trivalent chromium (Cr-III) yosanjikiza yoyera yoyera. Zimaphatikiza kutetezedwa kwa dzimbiri, mawonekedwe owoneka bwino okongoletsa, komanso mtengo wotsika - ndikupangitsa kuti ikhale imodzi mwazinthu zodziwika bwino zapamtunda zomangira zolimba kwambiri zomwe zimagwiritsidwa ntchito m'malo otetezedwa pang'ono.

Momwe Plating ya Blue-White Zinc Imagwirira Ntchito

Njirayi imaphatikizapo njira zitatu zotsatizana:

Electro-cleaning & activation: Bolt pamwamba ndi degreased ndi asidi adamulowetsa kuonetsetsa yunifolomu zinc adhesion.
Zinc electrodeposition: Zinc yoyera (8-12 µm) imayikidwa pamagetsi pazitsulo zachitsulo mu bafa la asidi kapena zamchere.
Blue-white passivation: Bawuti yomwe yangokutidwa kumene imamizidwa mu njira ya trivalent chromium (Cr-III) passivation solution, kupanga filimu yopyapyala yowonekera mpaka buluu yomwe imasindikiza zinki ndikupereka mawonekedwe owala abuluu-woyera.
Kuphika kwa hydrogen de-embrittlement: Maboti a Grade 10.9 amawotcha pa 190-220 ° C kwa maola 4-8 mkati mwa maola 4 a plating (ISO 9588) kuti atulutse haidrojeni wosakanikirana ndikupewa kusweka kochedwa.

Mfundo Zaukadaulo

Parameter	Kufotokozera	Standard	Ndemanga
Mtundu Wopaka	Zinc electroplate + blue-white passivation	ISO 2081 / ASTM B633	Trivalent Cr(III)
Makulidwe	8–12 µm (Fe/Zn 8c)	ISO 2081	Imasunga ulusi wokwanira
Kupopera mchere (NSS)	≥ 96 h dzimbiri loyera, ≥ 240 h dzimbiri lofiira	ISO 9227	Mtundu II, SC 1
Maonekedwe	Uniform buluu-wowala ndi iridescence	ISO 2081	Zokongoletsa + zogwira ntchito
Hydrogen De-embrittlement	Kuphika pa 190-220 ° C kwa 4-8 h mkati mwa 4 h kuchokera plating	Mtengo wa ISO9588	Zovomerezeka kwa Giredi 10.9
RoHS / REACH	Kugwirizana (Cr-VI free trivalent passivation)	2011/65/EU	Malo otetezeka
Friction Coefficient	µ = 0.12–0.20 (monga-yokutidwa)	ISO 16047	Ulamuliro wodalirika wotsitsa

Kukana kupopera mchere pa ISO 9227 kusalowerera ndale mchere kutsitsi (NSS). White dzimbiri = zinki dzimbiri mankhwala; red dzimbiri = chitsulo gawo lapansi dzimbiri. Hydrogen de-embrittlement ndiyofunikira pazomangira zolimba ≥ 320 HV pa ISO 4042.

Ubwino wa Maphunziro a Gulu 10.9

Kutsimikizika kowoneka bwino: Kutsirizira kowala, yunifolomu ya buluu-yoyera kumapangitsa zolakwika zapamtunda (zokanda, malo osatsekedwa, kuipitsidwa) zimawonekera nthawi yomweyo pakuwunika.
Kugwirizana kwa ulusi: Pa 8-12 µm, zokutira zimakhala zoonda mokwanira kuti zisunge kulekerera kwa ulusi (6g / 6h) popanda kugogodanso - ndizofunikira kwambiri pamagulu olimba kwambiri.
Kukangana kolamulidwa: Pamwamba ngati-wokutidwa umapereka chiwopsezo chokhazikika (µ ≈ 0.12–0.20), kuthandizira kuwerengera kodalirika kotengera torque.
Zotsika mtengo: Zinc electroplating ndiyo njira yotetezera dzimbiri yotsika mtengo kwambiri ya zomangira, zotsika mtengo kwambiri kuposa Dacromet kapena galvanising yotentha.
Kugwirizana ndi chilengedwe: Trivalent (Cr-III) passivation imakwaniritsa zofunikira za RoHS ndi REACH; mosiyana ndi njira zakale za hexavalent chromium (Cr-VI), sizimawononga chilengedwe kapena ntchito.

Zolepheretsa & Zochita Zabwino

Kuyika kwa zinki koyera kwa buluu kumapangidwira m'nyumba komanso malo otetezedwa pang'ono (magawo owononga C1-C2 pa ISO 12944). Kuti muwonetsere panja, malo a m'mphepete mwa nyanja (C3+), kapena ntchito zomwe zimafuna ≥ 480 h kukana kupopera mchere, ganizirani Dacromet kapena galvanising yotentha. Nthawi zonse tchulani kuphika kwa haidrojeni de-embrittlement pamaoda ogula a giredi 10.9 zomangira zinki.
