S235JR khoom yog dab tsi?
Steel qib S235JR yog ib tug nrov kev tsim kho thiab tshuab hlau uas yog ua raws li EN 10025-2 tus qauv. Kev faib tawm:Tsis yog - alloy structural steel. Cov khoom: Semi-cov khoom tiav, cov khoom ntev thiab cov ntawv kub- cov khoom 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 tustoughness 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 yield zog ntawm235 MPa rau. 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.
