Q345qC H steel yog ib yam ntawm lub zog siab thiab siab toughness structural steel, lub zog tensile ntawm Q345qC steel h beam yog ntau dua li cov hlau zoo tib yam, uas yog ib qho ntawm cov laj thawj tseem ceeb vim li cas nws tau siv dav hauv choj, nkoj, kev tsim kho, tshuab. manufacturing thiab lwm yam kev lag luam. Lub zog siab Q345qC hlau h beam tuaj yeem tiv taus ntau dua qhov hnyav thiab qhov hnyav, ua rau cov qauv muaj zog thiab ruaj khov dua. Nyob rau tib lub sijhawm, lub zog siab Q345qC h zoo li cov hlau kuj tuaj yeem txo qhov hnyav ntawm cov qauv, txhim kho kev ua haujlwm tag nrho thiab kev pabcuam lub neej ntawm cov qauv.
Q345qC H seem steel yog siv nyob rau hauv txuas hniav, nkoj, kev tsim kho, machinery manufacturing thiab lwm yam teb. Hauv kev tsim cov choj, Q345qC h beam hlau feem ntau yog siv rau hauv kev tsim cov choj girders, kab teeb, kev txhawb nqa thiab lwm yam khoom siv; nyob rau hauv shipbuilding, Q345qC h beam qauv yog feem ntau siv nyob rau hauv zus tau tej cov nkoj hulls, nkoj txuas hniav, nkoj txhawb nqa qauv, thiab lwm yam .; nyob rau hauv kev tsim kho, Q345qC h seem beam yog feem ntau siv nyob rau hauv zus tau tej cov high-sawv vaj tse txhawb nqa, thav duab, kab teeb thiab kab, thiab lwm yam .; nyob rau hauv lub tshav pob ntawm mechanical engineering, Q345qC steel h kem yog feem ntau siv nyob rau hauv zus tau tej cov machinery hnyav txhawb cov qauv, lub moj khaum, kab teeb thiab kab. Nyob rau hauv lub teb ntawm machinery manufacturing, Q345qC structural h beam yog feem ntau siv nyob rau hauv zus tau tej cov machinery hnyav txhawb cov qauv, hauv paus, bearings, thiab lwm yam.
