Thaum xaiv 1045 Chrome Plated Bar, txhais "kev ua tau zoo" rau hauv qhov ntsuas tau, cov lus hauv qab no yog qhov tseem ceeb:
1. Cov khoom siv tshuaj lom neeg muaj pes tsawg leeg: Nruab nrab- carbon structural steel nrog 0.42–0.50% carbon thiab 0.60–0.90% manganese, ua kom lub zog tawm los ntau dua lossis sib npaug rau 350 MPa thiab tensile lub zog ntawm 580-750 MPa tom qab tempering, muab ob qho tib si machining thiab tempering.
2. Nto Chrome Plating Thickness: Hydraulic shafts feem ntau siv 20 μm (0.0008 ") los yog tuab dua; rau hnyav-cov dej num lossis ib puag ncig marine, 25–30 μm (0.001″) raug xaiv, ua kom ntsev tsuag lub neej ntawm 48 h txog 500 h.
3. Nto Hardness thiab Roughness:
Chromium plating HV 850-1000 (kwv yees HRC 63-68), muab lub plhaub hnav-tiv taus; Tom qab kev sib tsoo zoo, Ra Tsawg dua lossis sib npaug ntawm 0.25 μm, txo qhov kev sib txhuam kub ntawm cov ntsaws ruaj ruaj los ntawm 8-12%.
4. Diameter kam rau ua thiab ncaj:
Standard qib h7 (-0/–0.025 mm txog Ø51 mm), siab- qib h6; Ncaj qis dua los yog sib npaug ntawm 0.3 hli / 1000 hli, kom tsis txhob muaj kev cuam tshuam hauv lub tog raj kheej ntev.
5. Induction Hardening (IHCP) Yuav Tsum Tau: Rau cov ntawv thov uas yuav tsum tau muaj kev cuam tshuam ntau dua, xaiv qhov "tempering + induction hardening + chrome plating" version: deg hardness HRC 50-52, zoo hardened txheej ntau dua los yog sib npaug rau 0.05 hli, dent resistance 3 zaug siab dua cov uas tsis yog-hardened.
6. Dimensions thiab Supply Length: Txheem txheej txheej 19-127 mm, ntev 4-6 m; qhov ntev sab nraum qhov no yuav tsum tau kev cai dov. Ua ntej muab qhov kev txiav txim, xyuas lub tshuab qhov siab tshaj plaws ua txoj kab uas hla thiab cov khoom siv ntev kom txo cov khib nyiab los ntawm cov saw hlau thib ob.
