Nws yog lub fastener ntawm kev xaiv rau automotive engine assemblies, hnyav machinery, cua turbine sib txuas, thiab structural steelwork qhov twg compact, high-clamping-force pob qij txha yuav tsum tau.

Qib 10.9 DIN 933 Hex Bolt nrog Blue-White Zinc Electroplating Finish

Ntu 1 — Qib 10.9: Chav Kawm Siab-Strength Fastener

Qib 10.9 yog qib thib ob-siab tshaj plaws cov cuab yeej cuab tam chav rau metric fasteners raws li ISO 898-1, zaum ntawm qib 8.8 dav siv thiab ultra-high-strength Qib 12.9. Nws muaj qhov sib npaug sib npaug ntawm lub zog siab, qhov ua tau zoo, thiab qhov ua tau zoo ntawm kev qaug zog, ua rau nws qhov kev qhia tshwj xeeb rau cov pob qij txha tseem ceeb hauv tsheb, lub zog, thiab cov tshuab hnyav.

Property Class Decoding

Thawj tus lej (10): Qhia 1/100 ntawm nominal yam tsawg kawg nkaus tensile lub zog nyob rau hauv MPa → yam tsawg kawg nkaus tensile zog = 1,000 MPa (tus qauv ntawm 1,040 MPa).
Tus lej thib ob (9): Qhia qhov sib piv ntawm qhov tsawg kawg nkaus yield zog rau yam tsawg kawg nkaus tensile zog × 10 → yield ratio = 0.90, lub ntsiab lus yam tsawg kawg nkaus yield zog = 940 MPa.

Ntu 2 - DIN 933: Tag Nrho Cov Xov Hexagon Bolt Standard

DIN 933 qhia tag nrho threaded hexagon-lub taub hau bolts nrog metric coarse pitch threads ntawm M1.6 txog M52. Txawm hais tias technically hloov los ntawm ISO 4017, DIN 933 tseem yog tus qauv siv feem ntau siv ntsia liaj qhov rooj hauv European cov ntaub ntawv kev yuav khoom, kev kos duab, thiab cov nqi ntawm cov ntaub ntawv thoob ntiaj teb.

Ntsiab Dimensional Nta

Tag nrho cov xov shank: Threading txuas mus rau tag nrho qhov ntev, ua kom qhov ntev ntawm qhov yooj yim thiab yooj yim rau cov khoom muag - ib feem hloov ntau qhov tuav-ntev-tshwj xeeb ib feem threaded bolts.
Hexagon taub hau: Dav thoob plaws cov tiaj tiaj (s) rau DIN EN ISO 272. Nominal taub hau qhov siab (k) muab cov kabmob txaus rau cov txheej txheem ntxhua khaub ncaws thiab kev sib txuas ntawm lub qhov (socket).
Metric coarse suab: Raws li ISO 261/ISO 724. Cov xov coarse muaj kev tiv thaiv ntau dua ntawm kev puas tsuaj ntawm qhov chaw, tsis tshua muaj kev kub nyhiab, thiab nrawm dua los sib sau ua ke ntau dua li lwm txoj hauv kev zoo.
Qib kam rau ua: Khoom qib A rau qhov ntau thiab tsawg ≤ M24 thiab ntev ≤ 10d lossis ≤ 150 mm; Cov khoom lag luam qib B rau qhov loj me (ISO 4759-1).

Kos Npe

Txhua Qib 10.9 DIN 933 bolt yog lub taub hau cim nrog "10.9" thiab cov chaw tsim khoom cov cim qhia raws li ISO 898-1. Cov xim xiav-dawb zinc tiav muab kev pom kev pom tam sim thiab pab nrog kev tswj xyuas zoo.

Ntu 3 - Xiav-White Zinc Electroplating

Xiav-dawb zinc (Zn / An / Cn / T0 rau ISO 2081, lossis Hom II SC 1 rau ASTM B633) yog zinc electroplated txheej tiav nrog trivalent chromium (Cr-III) xiav-dawb hloov xim txheej. Nws ua ke nrog kev tiv thaiv corrosion nruab nrab, qhov zoo nkauj zoo nkauj zoo nkauj zoo nkauj, thiab tus nqi qis - ua rau nws yog ib qho ntawm cov kev kho mob nrov tshaj plaws rau cov khoom siv muaj zog uas siv rau hauv ib puag ncig tiv thaiv ib puag ncig.

Yuav Ua Li Cas Xiav-White Zinc Plating Ua Haujlwm

Cov txheej txheem muaj peb theem ua ntu zus:

Electro-cleaning & activation: Lub ntsia liaj qhov rooj saum npoo yog degreased thiab acid-activated kom ntseeg tau tias zinc adhesion zoo ib yam.
Zinc electrodeposition: Ib txheej ntawm cov zinc ntshiab (8-12 µm) yog electrolytically tso rau hauv cov hlau substrate hauv cov kua qaub lossis alkaline zinc da dej.
Blue-dawb passivation: Cov ntsia liaj qhov rooj tshiab tau muab tso rau hauv qhov kev daws teeb meem trivalent chromium (Cr-III) passivation, ua rau nyias pob tshab-rau-xiav hloov dua siab tshiab zaj duab xis uas kaw cov zinc thiab muab cov yam ntxwv ci xiav-dawb tsos.
Hydrogen de-embrittlement ci: Qib 10.9 bolts yog ci ntawm 190-220 ° C rau 4-8 teev nyob rau hauv 4 teev ntawm plating (ISO 9588) kom tshem tawm cov hydrogen diffusible thiab tiv thaiv kom tsis txhob tawg tawg.

TS EN ISO 9227 Cov tshuaj tsw qab ntsev tsis haum (NSS). Dawb xeb = zinc corrosion khoom; liab xeb = steel substrate corrosion. Hydrogen de-embrittlement yog yuav tsum tau rau fasteners nrog hardness ≥ 320 HV ib ISO 4042.

Qhov zoo rau Qib 10.9 Daim Ntawv Thov

Visual quality assurance: Lub ci ci, xim xiav-dawb ua tiav ua rau muaj qhov tsis xws luag (scratches, unplated thaj chaw, kev sib kis) tam sim ntawd pom thaum kuaj.
Xov compatibility: Ntawm 8-12 µm, cov txheej yog nyias txaus los khaws cov qauv xov tolerances (6g / 6h) yam tsis muaj rov tapping - qhov tseem ceeb rau cov pob qij txha muaj zog.
Tswj kev sib txhuam: Raws li-plated nto muab ib qho kev sib txhuam coefficient (µ ≈ 0.12-0.20), txhawb kev txhim khu kev qha torque-based preload xam.
Nqi-zoo: Zinc electroplating yog txoj kev tiv thaiv corrosion zoo tshaj plaws rau cov fasteners, nrog cov nqi ua haujlwm qis dua Dacromet lossis kub-dip galvanising.
Environmental ua raws li: Trivalent (Cr-III) passivation raws li RoHS thiab REACH cov cai; Tsis zoo li qub hexavalent chromium (Cr-VI) cov txheej txheem, nws tsis muaj kev phom sij rau kev noj qab haus huv lossis kev ua haujlwm.

Kev txwv & Kev coj ua zoo tshaj plaws

Xiav-dawb zinc plating yog npaj rau sab hauv tsev thiab ib nrab tiv thaiv sab nraum ib puag ncig (corrosivity pawg C1-C2 rau ISO 12944). Rau kev raug sab nraum zoov ncaj qha, thaj chaw ntug dej hiav txwv (C3+), lossis daim ntawv thov uas xav tau ≥ 480 h ntsev tsuag, xav txog Dacromet lossis kub-dip galvanising. Ib txwm hais meej hydrogen de-embrittlement ci ntawm kev yuav khoom rau Qib 10.9 zinc-plated fasteners.
