Txheej txheem ha tw w21x122 w21x132 steel profile
h nqaj profile specification loj sib piv
W21x122 Hlau Baj H: "W21" txhais tau tias qhov siab ntawm cov hlau yog li 212 phaus, txog 181.5kg / m.
W21x132 H Profile Steel: Qhov siab yog tseem 21 nti (533.4MM), thiab qhov hnyav ib txhais ko taw yog 132 phaus, txog 196.2kg / m.
H Hlau profile Cov Khoom Siv Sib Pauv
A36 cov khoom siv hlau: C Tsawg dua lossis sib npaug ntawm {{1 {}}}}}}}}}}}}}}}}}}}}}}} 0.05, cu ntau dua los yog sib npaug rau 0.20 (thaum tooj liab-muaj hlau yog teev); yield strength Greater than or equal to 250MPa, tensile strength 400 - 550MPa, elongation Greater than or equal to 20%; Muaj cov cuab yeej siv cov khoom siv kho zoo, vuam cov khoom thiab kev ua cov khoom.
A572Gr5 {0 nqaj hlau steel khoom: c l ntau dua lossis sib npaug lossis sib npaug lossis sib npaug rau 0.05, nb 0. {005 - 0. 05; yield strength Greater than or equal to 345MPa, tensile strength 490 - 600MPa, elongation 22 - 35%, Charpy impact energy at 0 degree Greater than or equal to 45J; Muaj lub zog siab, siab tawv, zoo nkees ua hauj lwm thiab corrosion tsis kam.
A992 cov khoom siv: nws yog cov khoom siv tshwj xeeb siv rau cov qauv hlau. Nws cov txiaj ntsig lub zog yog feem ntau tsis tsawg tshaj li 345mpa, thiab nws lub zog tensile yog nruab nrab ntawm {2}} mpa mpa mpa. Nws muaj cov khoom muaj zog zoo, Weldability thiab txias. Nws yog feem ntau siv nyob rau hauv cov liaj teb nrog high qhov yuav tsum tau rau cov hlau ua haujlwm, xws li lub tsev qauv.
Kev sib piv ntawm W21x122 H nqaj seem thiab W21X132 steel h profile
Cov lus qhia tshwj xeeb: Ob qho tib si yog li 533.4Mm siab, tab sis qhov hnyav rau ib txhais ko taw (txog 181.5kg / m) phaus ib txhais ko taw (txog xyoo 196.2kg / m). Lub W21x132 steel profile muaj qhov chaw loj dua-ntu thiab nyhav dua nyob rau tib lub ntev.
Nqa khoom muaj peev xwm: vim qhov chaw muaj peev xwm hla ntawm W21X132 qauv hlau nqaj, lub peev xwm nqa tau yog qhov siab dua. Nyob rau hauv tib lub thauj khoom, qhov deformation ntawm W21x132 steel profile yuav me dua.
Tiffness: Lub sijhawm ntu ntawm inertia thiab kev tiv thaiv lub sijhawm ntawm W21x132 H steel profile loj dua li cov ntawm W21X122 steel nqaj, yog li nws lub pob tw zoo dua. Thaum raug thauj mus los, nws tsis tshua khoov thiab deform, thiab tuaj yeem ua kom muaj kev ruaj ntseg ruaj khov ntawm tus qauv.
