Q345 Carbon Steel Material
steel Product Introduction
Q345B steel plate Product introduction: Q345A (GB/T 1591-1994) ω/% Performance and application: a naming method similar to Q235. Q345a,Q345b,Q345c,Q345d,Q345e. This is the classification of grades, which represents that the impact temperature is different! For Q345A, there is no impact; The impact is 345B at room temperature; Q345C, 0 degree impact; Q345D is – 20 degree impact; Q345E is – 40 degree impact. At different impact temperature, the impact value is also different. In plate, it belongs to low alloy series. Among the low alloy materials, this kind of material is the most common. Q345 used to be called 16Mn.
