EN39 S235GT thiab Q235 yog ob hom hlau siv rau kev tsim kho.
EN39 S235GT yog qib hlau txheem European uas hais txog cov tshuaj lom neeg 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 qib hlau Suav. Nws sib npaug rau EN tus qauv S235JR qib hlau uas feem ntau siv hauv Tebchaws Europe. Q235 hlau muaj cov ntsiab lus carbon ntawm 0.14% -0.22%, cov ntsiab lus manganese tsawg dua 1.4%, cov ntsiab lus phosphorus ntawm 0.035%, cov ntsiab lus sulfur ntawm 0.04%, thiab cov ntsiab lus silicon ntawm 0.12%. Lub zog tensile kawg ntawm Q235 yog 370-500 MPa.
Hauv kev xaus, EN39 S235GT thiab Q235 muaj cov tshuaj sib xws tab sis cov khoom siv kho tshuab sib txawv me ntsis. Qhov kev xaiv ntawm ob qho no nyob ntawm daim ntawv thov tshwj xeeb thiab cov kev xav tau ntawm qhov project.
