Q355 A572GR50 H kem steel
【GNEE Group cov neeg siv khoom tuaj xyuas lub Hoobkas】
Khoom Description
Cov khoom siv ceev ntawm Q355H profile hlauyog 7.85 grams / cubic centimeter. Raws li GB / T 1591-2018, Q355 steel H beam muab faib ua peb qib zoo: Q355B, Q355C thiab Q355D. "Q" yog thawj tsab ntawv ntawm Suav Pinyin, qhia tias muaj zog tawm los. "355" yog qhov tsawg kawg nkaus tawm lub zog ntawm 355MPa thiab lub zog tensile ntawm 470 txog 630Mpa thaum cov hlau thickness tsawg dua 16 hli.
A572Gr50 H- zoo li cov hlau muaj me me ntawm cov ntsiab lus alloying ntxiv rau hauv cov hlau kom muaj zog ntawm cov hlau, yog li nws tuaj yeem hu ua qis- alloy siab- lub zog steel. A572Gr50 H-beam belongs rau qib American standard, thiab nws kuj ua raws li American cov qauv.

Kev sib piv ntawm Q355 thiab A572Gr50 H seem nqaj
Q355 thiab A572GR50 H channel steel yog ob hom hlau feem ntau siv hauv kev tsim kho. Txawm hais tias lawv yuav zoo sib xws thaum xub thawj siab ib muag, muaj qee qhov sib txawv tseem ceeb uas ua rau lawv sib nrug.
Ua ntej tshaj plaws, Q355 H steel beam yog Suav tus qauv hlau, thaum A572GR50 H nqaj hlau yog Asmeskas tus qauv hlau. Qhov no txhais tau hais tias ob lub steels muaj cov tshuaj sib txawv thiab cov khoom siv kho tshuab.
Los ntawm qhov kev xav ntawm cov tshuaj muaj pes tsawg leeg, Q355 H ntu muaj Si, Mn thiab Cu cov ntsiab lus siab dua, thaum A572GR50 beam steel qauv muaj ntau dua C thiab V cov ntsiab lus. Qhov sib txawv ntawm qhov sib xyaw ua rau muaj qhov sib txawv hardness thiab lub zog muaj zog.
Mechanically, Q355 beam ntawm steel muaj siab zog yield zog thiab tensile zog tshaj A572GR50 H zoo li tus hlau beam. Qhov no txhais tau tias Q355 H-beam yog cov hlau ruaj khov thiab ua haujlwm zoo dua qub, zoo tagnrho rau cov ntawv thov uas muaj zog thiab lub neej ntev yog qhov tseem ceeb.
