Nrog rau qhov elongation ntawm 35-40% thiab ib seem shrinkage ntawm 96%, cov hlau ua kom txaus ductility ua ntej tawg, cia nws nqus zog thiab tiv thaiv nkig tsis ua hauj lwm.
Tsis tas li ntawd, cov khoom siv ntawm A992 Wide Flange H Beams yog CE- tau lees paub thiab ua raws li EN10025 / EN10034 cov qauv thoob ntiaj teb, ua kom muaj cov tshuaj lom neeg ruaj khov thiab cov khoom siv kho tshuab. Qhov no ua rau nws tsim nyog rau cov ntawv thov uas xav tau cov khoom siv siab sib xws, xws li cov khoom siv hluav taws xob nuclear.
Txheej txheem ntawm A992 Wide Flange H Beams
A992 H-Beam feem ntau yog siv rau hauv cov qauv hlau, cov khoom siv hluav taws xob nuclear txhawb nqa cov qauv, thiab cov ntawv siv zoo sib xws. Nws cov txheej txheem kub - dov khaws cia cov hlau ntws cov kab, txo qis kev ua haujlwm tsis zoo, ua rau nws tsim nyog rau kev siv ncaj qha lossis ntxiv machining, xws li txiav, drilling, thiab vuam.
Thaum ua tiav, yuav tsum tau ua raws li cov kev ceev faj hauv qab no: ntxuav cov oxide txheej ua ntej vuam kom tiv thaiv hydrogen-induced cracking; txiav yog pom zoo siv cov plasma los yog laser los txo cov cua sov- thaj tsam cuam tshuam; Thaum lub sij hawm sib dhos, kho cov flanges thiab lub vev xaib kom zoo kom ntseeg tau tias tag nrho cov qauv kev ruaj ntseg. Tsis tas li ntawd, A992 Structural Steel Beams raug xa mus rau hauv thawj lub ntim ntim, uas yuav pab txo qis xeb thaum thauj mus los.
