 E355: Qib siab muaj zog nrog cov cim qhia txog lub zog zoo dua thiab kev cuam tshuam zoo dua li E235, tsim nyog rau cov ntawv thov uas xav tau kev thauj khoom ntau dua.

 2.2 Cov Tshuaj Lom Zem (E235 ua Piv Txwv)

 Khoom C Si Mn P S

Cov ntsiab lus (%) 0.17-0.22 0.10-0.35 0.40-0.80 ≤0.035 ≤0.035

2.3 Cov Khoom Siv Kho Tshuab (E235 ua Tus Siv)

 Lub zog tensile: 440-540 MPa

 Lub Zog Tawm:≥290 MPa

 Feem Pua ntawm Kev Ntev:≥12%

 2.4 Cov Cai ntawm Kev Xa Khoom

 Tus qauv tso cai rau ntau yam kev xa khoom, raws li kev pom zoo ntawm tus neeg muag khoom thiab tus neeg yuav khoom:

 BK (Kub-tiav lawm tawv): Muab tsis muaj kev kho cua sov, khaws cia qhov nyuaj tom qab ua haujlwm txias

 BKW (Ua haujlwm txias me ntsis): Ua haujlwm txias me ntsis nrog kev ua kom zoo nkauj

 GBK (Annealed): Annealed tom qab ua haujlwm txias

 NBK (Normalized): Muab rau hauv qhov xwm txheej normalized

 3. Kev Lag Luam Daim Ntawv Thov

EN 10305-5 cov kav hlau feem ntau yog siv rau hauv cov ntawv thov kev tsim khoom raug. Cov kev siv feem ntau suav nrog:

 Cov Txheej Txheem Kis Hydraulic: Cov roj hydraulic hauv cov tshuab siv hauv kev tsim kho thiab cov cuab yeej siv tshuab, xav tau qhov loj me meej thiab cov nplaim sab hauv du kom ntseeg tau tias kev kis kua dej zoo.

 Cov Txheej Txheem Tswj Xyuas Pneumatic: Cov kab xa cua compressed nrog cov kev cai nruj rau kev sib khi kom raug.

 Kev Tsim Khoom Siv Tsheb: Cov kav dej txhaj roj siab thiab cov kav dej tswj lub zog—ob qho tib si tseem ceeb ntawm kev nyab xeeb.

 Kev Siv Tshuab Dav Dav: Siv ua cov khoom seem rau cov tes tsho precision shaft, cov tes tsho qhia, thiab cov qauv txhawb nqa rau kev ua haujlwm machining tom qab.

 Kev Sib Koom Tes Khoom Siv Hauv Kev Lag Luam: Cov tes tsho sensor, cov raj ntsuas, thiab cov ntawv thov precision zoo sib xws.

 4. Cov Lag Luam Tseem Ceeb

Cov khoom lag luam nyob rau hauv EN 10305-5 feem ntau yog pab cov lag luam hauv qab no:

Kev Tsim Tsheb thiab Tsheb Lag Luam

Cov Tshuab Siv Thiab Cov Khoom Siv Ua Liaj Ua Teb

Kev Tsim Khoom Siv Hydraulic thiab Pneumatic

Cov Khoom Siv Dav Dav thiab Kev Ua Haujlwm Zoo

Kev Sib Koom Tes Hauv Kev Lag Luam Automation thiab Kev Tswj Xyuas Systems

5. Kev Tso Chaw Ua Lag Luam thiab Tus Nqi

EN 10305-5 tsis yog cov kav hlau dav dav. Nws yog lub hom phiaj rau kev lag luam kav hlau tshwj xeeb uas muaj kev ua haujlwm siab, kev ntseeg siab siab, thiab muaj txiaj ntsig zoo. Nws cov txiaj ntsig tseem ceeb suav nrog:

Muab cov neeg siv khoom nrog kev kwv yees thiab kev txheeb xyuas qhov ntev thiab cov ntsuas kev ua tau zoo

Txo cov khoom pov tseg thiab cov nqi kho dua tshiab rau cov neeg siv khoom downstream thaum lub sijhawm machining thiab sib dhos ua ke

Xyuas kom ruaj khov ua haujlwm ntev ntawm cov khoom siv kawg hauv qab kev ua haujlwm siab thiab kev ua haujlwm siab

Rau cov neeg xa khoom xa tawm cov yeeb nkab hlau hauv Suav teb, EN 10305-5 yog ib qho ntawm cov qauv nkag mus rau theem pib rau kev nkag mus rau European high-end precision manufacturing supply chain. Kev muaj peev xwm muab cov khoom lag luam raws li tus qauv no ua rau muaj kev lees paub los ntawm cov neeg siv khoom European nruab nrab mus rau qib siab hauv cov khoom siv tsheb, cov tshuab hydraulic, thiab lwm yam.
