Q235 Q355 H Beam Steel
Khoom Description
Q235 yog cov khoom siv carbon steel. Cov pa roj carbon steel yog cov hlau uas muaj hlau thiab carbon, tab sis cov ntsiab lus carbon tsawg dua 2%. Tseem muaj qee qhov me me ntawm silicon, manganese, sulfur, thiab phosphorus. Cov hlau uas muaj leej faj thiab phosphorus nrog cov ntsiab lus ntau dua 0.35% tab sis tsawg dua 0.5% yog hu ua "cov pa roj carbon zoo tib yam". Cov ntsiab lus ntawm sulfur nyob rau hauv high carbon steel thiab high carbon steel yog tsawg heev, thaum cov sulfur thiab phosphorus cov ntsiab lus nyob rau hauv high carbon steel yog ob qho tib si hauv qab no 0.3%.
Q355 steel muaj ntau yam zoo dua lwm yam steels. Nws muaj cov khoom siv zoo heev, siab zog thiab zoo weldability. Tsis tas li ntawd, Q355 steel kuj muaj qhov zoo corrosion kuj, siab kub tsis tshua muaj zog toughness thiab siab qaug zog. Nws haum rau ntau yam kev lag luam thiab yog tus nqi - cov khoom siv tau zoo thiab txhim khu kev qha.
