Dab tsi yog qhov tseem ceeb ntawm Q355 steel kauj hauv kev lag luam tsheb?
① Lub zog siab ua kom lub teeb yuag (15% - 20% qhov hnyav txo), txhim kho roj / hluav taws xob efficiency; ② Zoo toughness thiab weldability, haum rau automotive manufacturing txheej txheem; ③ Tus nqi zoo dua- ua tau zoo dua li cov hlau alloy muaj zog, txo nqi tsheb tag nrho.
Dab tsi yog qhov zoo ntawm Q355 steel kauj hloov Q345 steel kauj?
Lub zog muaj zog ntau dua (355MPa vs 345MPa), zoo dua weldability, zoo dua qis-kub toughness, thiab ntxiv qhov hnyav txo nyob rau hauv tib lub load, ua rau nws hloov dua tshiab rau Q345.
Dab tsi yog qhov tsis zoo ntawm Q355 steel kauj piv rau aluminium alloy hauv kev siv tsheb?
Higher density (limited weight reduction), slightly worse formability, but lower cost, mature welding/processing technology, and convenient maintenance, making it suitable for heavy-duty applications such as commercial vehicles.
Dab tsi yog qhov cuam tshuam ntawm Q355 steel coil yuav cov nqi ntawm tag nrho lub tsheb? Txawm hais tias tus nqi tsev yog me ntsis siab dua Q235, nws lub teeb yuag tsim txo cov khoom siv thiab txo cov roj / hluav taws xob noj, uas ua rau txo qis tag nrho cov nqi mus sij hawm ntev -, tshwj xeeb tshaj yog nyob rau hauv lub lag luam tsheb sector uas nws muaj txiaj ntsig zoo.
Yuav ruaj khov npaum li cas ntawm Q355 steel coils?
Loj hauv tsev steel mills xws li Baosteel, Maanshan Iron & Steel, thiab Ansteel yog tag nrho cov tsim nws nyob rau hauv ntau qhov ntau, kom muaj ib tug ruaj khov khoom nrog ib tug ntau yam ntawm specifications (thickness 1.5-20mm, dav 1000-2000mm), haum rau bulk xav tau ntawm kev lag luam automotive.
