Q: Dab tsi yog A992 H-Beam steel, thiab nws siv qhov twg?
A:A992 H-Beam steel yog siab-lub zog, qis- alloy structural steel dav siv hauv tsev thav duab, txuas hniav, thiab cov chaw tsim khoom. Nws yog tsim tshwj xeeb los hloov A36 thiab A572 Gr.50 hauv kev tsim kho, muab lub zog zoo dua, weldability, thiab kev ua haujlwm seismic.
Q: Dab tsi yog cov khoom siv ntawm A992 steel beam?
A:A992 H-Beams muaj qhov tsawg kawg nkaus lub zog ntawm 345 MPa (50 ksi) thiab tensile lub zog ntawm 450 txog 620 MPa (65-90 ksi). Lub zog siab no tso cai rau me me hla- ntu, txo qhov hnyav ntawm cov qauv thaum tswj kev thauj khoom{10}}cov kabmob muaj peev xwm thiab ruaj khov.
Q: Yuav ua li cas weldability ntawm A992 H-Beams?
A:A992 steel muaj qhov sib npaug ntawm cov pa roj carbon tsawg, uas ua kom muaj kev sib txuas zoo heev. Nws tuaj yeem welded siv cov txheej txheem txheej txheem xws li SMAW, GMAW, thiab FCAW, nrog tsawg kawg preheating lossis post-weld cua sov yuav tsum tau, ua rau nws zoo tagnrho rau ntawm - qhov chaw tsim kho.
