Q345 C Steel Channel
Channel C Steel Product Description
Q345 c seem steel yog cov khoom siv hlau. Nws yog cov hlau tsis tshua muaj hlau (C<0.2%) and is widely used in buildings, bridges, vehicles, ships, pressure vessels, etc.
Q345 channel beam hom kev taw qhia: Q sawv cev rau lub zog ntawm cov khoom siv no; 345 yog hais txog tus nqi tawm los ntawm cov khoom siv no, uas yog nyob ib ncig ntawm 345 MPa, thiab tus nqi tawm los yuav txo qis thaum lub thickness ntawm cov khoom nce.
Q345 cov qauv channel tuaj yeem muab faib ua Q345A c channel bar, Q345B c channel beam, Q345C steel channel seem, Q345D c bar steel, Q345E structural steel channel raws li qib.
Q345 cov qauv c channel series qib sawv cev rau qhov sib txawv ntawm qhov kub thiab txias. Q345A qib c zoo li tus hlau tsis muaj kev cuam tshuam; Q345B qib c seem steel nqaj muaj qhov cuam tshuam ntawm 20 degrees qhov kub thiab txias; Q345C c seem channel muaj kev cuam tshuam ntawm 0 degrees; Q345D qib c channel steel nqaj muaj qhov cuam tshuam -20 degree; Q345E c di ncauj channel muaj qhov cuam tshuam -40 degree. Degree ntawm kev cuam tshuam, ntawm qhov sib txawv ntawm qhov kub thiab txias, qhov cuam tshuam qhov tseem ceeb kuj txawv.
Q345 steel hlau channel muaj cov cuab yeej zoo txhua yam, zoo plasticity thiab weldability. Nws yog siv los ua cov qauv, cov khoom siv kho tshuab, cov qauv hauv tsev, thiab cov qauv hlau dav dav uas dais dynamic loads xws li nruab nrab thiab tsis tshua muaj siab cov hlab ntsha, roj tso tsheb hlau luam, tsheb, cranes, mining machinery, fais fab chaw nres tsheb, txuas hniav, thiab lwm yam., siv nyob rau hauv kub dov los yog normalized tej yam kev mob, yuav siv tau nyob rau hauv ntau yam qauv nyob rau hauv txias cheeb tsam hauv qab no -40 degree .
