Mechanical Properties - S235JR vs S235J2
| Qib | Yield zog ReH (MPa) | Tensile zog Rm (MPa) | Elongation A (%) | Charpy V Test Temp (degree) | Impact Zog Longitudinal (J) |
|---|---|---|---|---|---|
| S235 JR | 235 | 360–510 | 26 | +20 | 27 |
| S235J2 | 235 | 360–510 | 24 | -20 | 27 |
Qhov cuam tshuam qhov kub ntawm qhov sib txawv yog qhov tseem ceeb rau cov kws tsim khoom xaiv cov hlau rau qis - qhov kub thiab txias.
Daim ntawv thov ntawm S235JR thiab S235J2 Steel Phaj
Ob qib yog siv dav hauv:
- Freight tsheb thiab trailer
- Transmission towers
- cranes thiab lifting khoom
- bulldozers thiab excavators
- Cov tsheb thauj khoom pov tseg thiab kev lag luam machinery
S235JR yog qhov zoo tagnrho rau kev siv cov qauv siv nyob rau hauv ib puag ncig qhov kub thiab txias, thaum S235J2 nyiam rau cov mob khaub thuas uas yuav tsum tau muaj zog ntxiv.
Vim li cas thiaj xaiv GNEE rau S235JR thiab S235J2 Steel
GNEE Steel muab:
- Cov khoom siv ncaj qha los ntawm cov chaw tsim khoom nrog cov khoom muaj nyob
- EN 10204 / Mill Test Certificate (MTC)
- Kev sib tham pub dawb thiab qauv kev txhawb nqa
- Kev cai txiav thiab fabrication kev pab
- Kev tswj xyuas nruj zoo nrog rau kev kuaj tshuab thiab tshuaj lom neeg
Qhov no ua kom muaj qhov zoo ib yam thiab kev ntseeg siab rau txhua qhov koj xav tau ntawm cov qauv steel.
Rau siab - zoo S235JR thiab S235J2 steel daim hlau, GNEE Steel yog koj tus khub ntseeg siab. Ob leeg qis- carbon structural steels muab zoo weldability, txias- tsim cov khoom, thiab toughness haum rau ntau yam kev lag luam thiab kev tsim kho.
Tiv tauj peb hnub no rau qhov tseeb S235JR & S235J2 steel phaj nqe daim ntawv teev npe
S235JR khoom yog dab tsi?
Steel qib S235JR yog ib qho kev siv dav dav thiab tshuab hlau uas tau ua raws li EN 10025-2 tus qauv. Kev faib tawm: Tsis yog - alloy structural steel. Cov khoom lag luam: Semi-cov khoom tiav, cov khoom siv ntev thiab cov ntawv kub dov, hlau pas nrig thiab forgings.
S235JR steel sib npaug yog dab tsi?
ASTM A36: ASTM A36 yog ib qho American standard carbon structural steel specification, uas yog feem ntau siv nyob rau hauv cov qauv siv. Nws yog ze tshaj rau S235JR hais txog cov tshuaj muaj pes tsawg leeg.
JR sawv cev rau dab tsi hauv S235JR?
S235JR: Tsab ntawv "S" sawv cev rau "Structural," qhia tias cov hlau yog cov hlau tsim. Tus lej "235" sawv cev rau qhov tsawg kawg nkaus yield zog, piv txwv li, 235 MPa (megapascals). Lub cim "JR" yog hais txog qhov toughness thiab cuam tshuam tsis kam ntawm cov hlau.
Lub zog tawm los ntawm S 235 Jr yog dab tsi?
Qib S235JR muaj qhov tsawg kawg nkaus tawm lub zog ntawm 235 MPa. Lub zog cuam tshuam ntawm chav tsev kub ntawm 20℃yog tsawg kawg yog 27 joules. Cov hlau ntawm qib S235JR yog qhov tsim nyog rau qis- qhov kev ntxhov siab hauv steel thiab mechanical engineering.
