JIS 3101 SS400 STEEL YEEB NKAB

JIS 3101 yog ib tus qauv rau cov qauv kev tsim qauv uas tau cov qauv siv rau cov tshuaj lom neeg Japanese thiab cov khoom siv kho tshuab ntawm cov ntaub ntawv.

SS400 yog qib pib hauv cov qauv no, qhov twg "steel qauv" (tus lej "400" qhia tias nws lub zog tsawg tshaj plaws yog 400 mpa.

Cov tshuaj lom neeg cov tshuaj lom neeg yuav tsum muaj rau SS400 yog nyob rau sab nrauv thiab nws yog qhov tsim nyog rau cov kev siv qauv tsim.

• Pa roj carbon (c): tsawg dua los yog sib npaug rau 0. 30%

• manganese (mn): tsawg dua lossis sib npaug nrog 1.60%

• Phosphorus (p): tsawg dua lossis sib npaug rau 0. 050%

• Cov tub rog Sulphur: tsawg dua lossis sib npaug rau 0. 050%

• Silicon (Si): tsis txwv tsis pub tsawg, feem ntau tsawg dua lossis sib npaug nrog 0. 35}. 35\/30%

NCO TSEG: SS400 muaj qhov tsis tshua muaj qhov yuav tsum muaj rau cov khoom siv alloy thiab tsom rau cov nqi them rau cov nqi thiab kev ua haujlwm.

• Lub zog tensile: {400-510 mpa mpa
• Paib lub zog: ntau dua los yog sib npaug rau 245 MPa
• Elongation: ntau dua los yog sib npaug rau 17% (ntsuas cua (gauge ntev 50 hli)
• Kev Cuam Tshuam Cov Khoom Siv Boughness: Feem ntau, cuam tshuam kub kev ua tau zoo tsis tas yuav tsum tau, thiab nws yog qhov haum rau ib puag ncig kub li qub.

• Ntaus: Nws tuaj yeem yog welded steel yeeb nkab (xws li erw resistance vuam) lossis seamless steel yeeb nkab, nyob ntawm cov ntawv thov kev cai.

1. Welded Steel Kav: Tus nqi qis, haum rau cov raj xa hluav taws xob tsawg lossis cov qauv tsim qauv kev txhawb nqa.
2. Seamless steel kav: Lawv muaj lub zog siab dua thiab siv rau cov khoom siv hluav taws xob siab lossis cov khoom siv tshuab.

• Siv Tshuab:Kub rolling lossis txias kos duab sib sau ua ke, qhov saum npoo yuav yog galvanized, pleev xim lossis tawv dub (tsis kho).

• Lub Tsev Cov Qauv: Scaffolding, Ru Trades, Cov Ntawv Txhawb Nqa.
• Machinery Raug:Kev ua liaj ua teb machinery yam, conveyor thav ntawv.
• Cov Webing System:Dej thauj khoom thiab roj tsheb thauj khoom (xeb kev pab tiv thaiv).
• Kev Lag Luam Automotive:Tsis yog tus qauv tseem ceeb, xws li chassis seem.

• Suav GB \/ T 700:Sib raug rau Q235B (cov khoom siv neeg kho mob tau kaw, tab sis cov phosphorus thiab cov tub ntxhais sau ntawv ntawm Q235B yog qis dua).

• American Astm:Zoo ib yam li ANTM A36, tab sis cov txiaj ntsig lub zog ntawm A36 yog qhov siab dua me ntsis (ntau dua lossis sib npaug nrog 250 MPA).

• European EN:Zoo ib yam li S235JR (EN 10025).

• Ntawj ntom:7.85 g \/ cm³

• Elastic modulus: {200-210 GPA

• Coefficient ntawm thermal expansion:Kwv yees li 11.7 × 10⁻⁶ \/ degree (20-100 degree)

• Hwj txwv: Zoo. Preheating yog yuav tsum tau (yog tias cov pa roj carbon yog ze rau qhov txwv sab saud) kom tiv thaiv kev tawg.

• Lub cev muaj peev xwm: Haum rau cov txheej txheem xws li kev puas yog khoov thiab khib nyiab, tab sis kev kho anevering yog xav tau thaum cov ntsiab lus carbon yog siab.

• Luam ntawv: Nruab nrab, xav kom tsim nyog lubrication.

• Tshuaj Ntsuam Xyuas: Tensile kuaj, khoov xeem (los xyuas cov qauv ua haujlwm), kuaj qhov ntev.
• Nto Zoo: Tsis muaj kab nrib pleb, nti lossis lwm yam tsis xws luag, thiab txheej me ntsis xeb.

• Corrosion Kuj:Pluag, yuav tsum tau pleev xim, galvanizing lossis tu ib txwm.
• Tsawg-kub siv: Tsis pom zoo rau kev siv hauv qhov tsawg-kub kev chim ib puag ncig (xws li hauv qab {1}} degree).
• Lwm Txoj Kev Xaiv: Thaum muaj lub zog siab lossis huab cua tsis kam, SM490 (JIS G3106) lossis coated steel kav poom tuaj yeem xaiv tau.

JIS 3101 SS400 STEEL PIPES tau dav siv nyob rau hauv cov qauv txheej txheem ib txwm vim lawv kev lag luam, ua haujlwm zoo thiab ua haujlwm. Txawm li cas los xij, cov neeg siv yuav tsum tau txheeb xyuas seb cov ntaub ntawv ua tau zoo dua lossis kev tiv thaiv ntxiv, xws li kub, thiab txias, thiab muaj zog. Qhov raug xaiv kom raug raws li cov khoom siv tau sib npaug thiab ua kom ruaj khov thiab ua kom muaj kev nyab xeeb ntawm txoj haujlwm.
