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.

Puas yog S235JR yog cov hlau me me?

S235JR yog ib qib tshwj xeeb ntawm cov hlau me metxhais raws li EN 10025. Thaum nws zaum hauv cov hlau me me, nws tau tswj cov tshuaj thiab cov khoom siv kho tshuab uas ua rau nws xav tau ntau dua li cov hlau tsis zoo lossis tsis zoo.

S235JR steel khoom yog dab tsi?

S235JR yog alow-carbon, tsis yog- alloy structural steeltxhais los ntawm EN 10025-2 tus qauv. "S" sawv cev rau "structural," txhais tau hais tias nws yog npaj rau siv nyob rau hauv load-bearing qhov chaw ntawm lub tsev, machinery, los yog infrastructure.

Qhov txawv ntawm S235JR thiab S355JR yog dab tsi?

Yield zog:S235JR muaj lub zog nominal yield ntawm 235 MPa, thaum S355JR muaj lub zog ntau dua ntawm 355 MPa. Qhov no 50% nce nyob rau hauv lub zog tawm los ua rau S355JR muaj peev xwm tiv taus cov loads ntau dua, ua rau nws tsim nyog rau siab - cov ntawv thov kev ntxhov siab.
