A36/A572GR50/A992 W12x65 W12x72 W12x79 H Beam Profile
A36 h hom beam yog American standard carbon structural steel uas ua raws li ASTM A36 / A36M tus qauv. Nws yog dav siv nyob rau hauv kev tsim kho, txuas hniav, machinery manufacturing thiab lwm yam teb. Nws yog haum rau welded los yog bolted yam ntxwv qhov chaw thiab yog sib npaug rau lub domestic Q235 h seem hlau.
Lub zog yield ntawm A36 h zoo li tus nqaj yog ntau dua lossis sib npaug li 250 MPa (tus nqi tsawg kawg), lub zog tensile yog 400 ~ 550 MPa, thiab elongation yog ntau dua lossis sib npaug li 20% (zoo heev yas deformation muaj peev xwm).
A572GR50 h beam seem yog Asmeskas tus qauv siab -lub zog qis- alloy structural steel uas ua raws li ASTM A572 / A572M tus qauv. Lub zog tawm ntawm A572GR50 steel h profile yog ntau dua lossis sib npaug ntawm 345 MPa (50ksi), lub zog tensile yog 450–585 MPa (65–85ksi), thiab elongation yog ntau dua lossis sib npaug li 18%. Nws haum rau siab -load scenarios xws li txuas hniav thiab vaj tse.
A992 h hlau beam yog tus qauv American siab -lub zog qis- alloy structural steel, tshwj xeeb tsim rau kev tsim kho, thiab ua raws li tus qauv ASTM A992. Lub zog tawm los (MPa) ntawm A992 h seem hlau yog ntau dua lossis sib npaug li 345. Nws muaj cov khoom ntawm lub zog siab, siab tawv thiab corrosion kuj, thiab yog dav siv hauv siab - nce vaj tsev, txuas hniav thiab lwm yam khoom thauj -cov kabmob.
