Q355 yog ib hom hlau. Nws yog ib hom low-alloy high-strength steel structural steel, dav siv nyob rau hauv choj, tsheb, nkoj, tsev, siab hlab ntsha, khoom siv tshwj xeeb, thiab lwm yam., qhov "Q" txhais tau tias yield zog, 355 txhais tau hais tias lub yield zog ntawm no. steel yog 355MPa, thiab yuav hloov nrog lub sijhawm. Raws li cov thickness ntawm cov khoom nce, nws cov nqi tawm los txo.
Q355 yog cov hlau tsis tshua muaj hlau uas muaj zog heev.
Daim ntawv thov teb ntawm Q355:
Q355 steel yog dav siv nyob rau hauv txuas hniav, tsheb, nkoj, kev tsim kho, siab hlab ntsha, khoom siv tshwj xeeb thiab lwm yam teb.
Q355 steel yog haum rau nws zoo heev vuam kev ua tau zoo, toughness, processability thiab corrosion kuj.
Cov yam ntxwv ntawm Q355:
Lub zog tawm ntawm Q355 steel yog 355MPa, uas txhais tau hais tias nws tuaj yeem tiv thaiv sab nraud ntawm 355MPa yam tsis muaj cov yas deformation nyob rau hauv qee yam mob.
Tus nqi tawm los ntawm Q355 steel yuav txo qis thaum lub thickness ntawm cov khoom nce.
Cov ntsiab lus carbon ntawm Q355 steel yog nyob nruab nrab ntawm 0.1% thiab 0.25%, thiab alloying ntsiab xws li manganese , silicon , vanadium , niobium thiab titanium ntxiv, thiab cov tag nrho cov ntsiab lus alloy yog kwv yees li 3%.
Kev sib piv ntawm Q355 thiab Q345:
Q355 yog qhov ua tiav ntawm Q345 thiab muaj cov khoom zoo sib xws ntawm lub cev thiab tshuaj lom neeg tab sis nrog qee yam kev txhim kho.
