EN39 S235GT thiab Q235 yog ob qib steel siv rau kev tsim kho.
EN39 S235GT yog European qauv steel qib uas hais txog cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab ntawm cov hlau. Nws muaj Max. 0.2% carbon, 1.40% manganese, 0.040% phosphorus, 0.045% sulfur, thiab tsawg dua 0.020% Al. Lub zog tensile kawg ntawm EN39 S235GT yog 340-520 MPa.
Q235, ntawm qhov tod tes, yog Suav tus qauv steel qib. Nws yog sib npaug rau EN tus qauv S235JR steel qib uas feem ntau siv hauv Tebchaws Europe. Q235 steel muaj cov ntsiab lus carbon ntawm 0.14% -0.22%, manganese cov ntsiab lus tsawg dua 1.4%, phosphorus ntsiab lus ntawm 0.035%, sulfur ntsiab lus ntawm 0.04%, thiab cov ntsiab lus silicon ntawm 0.12%. Lub zog tensile kawg ntawm Q235 yog 370-500 MPa.
Hauv cov ntsiab lus, EN39 S235GT thiab Q235 muaj cov tshuaj lom neeg zoo sib xws tab sis cov khoom sib txawv me ntsis. Kev xaiv ntawm ob yog nyob ntawm daim ntawv thov tshwj xeeb thiab cov kev xav tau ntawm qhov project.
