薄Q345B钢板 是用热轧或冷轧方法生产的厚度在0.2-4mm之间的Q345B钢板 。薄Q345B钢板 宽度在500-1400mm之间。根据不同的用途，薄Q345B钢板 采用不同材质钢坯轧制而成。
Thin Q345B plate is a Q345B steel plate produced by hot rolling or cold rolling method with the thickness of 0.2-4mm. Thin Q345B steel plate width between 500-1400mm. According to different purposes, the thin Q345B steel plate with different steel billet rolling.
通常采用材质有普碳钢、优碳钢、合金结构钢、碳素工具钢、不锈钢、弹簧钢和电工用硅钢等。它们主要用于汽车工业、航空工业、搪瓷工业、电气工业、机械工业等部门。薄Q345B钢板 除轧制后直接交货之外，还有经过酸洗的、镀锌和镀锡等种类。
Materials are usually carbon steel, carbon steel, alloy structural steel, carbon tool steel, stainless steel, spring steel and electrical steel, etc.. They are mainly used in automobile industry, aviation industry, enamel industry, electric industry, machinery industry and so on. In addition to the direct delivery of thin Q345B plate after direct delivery, but also after pickling, galvanized and tin and other types of.

厚Q345B钢板 是厚度在4mm以上的Q345B钢板 的统称，在实际工作中，常将厚度小于20mm的Q345B钢板 称为中板，厚度＞20mm至60mm的Q345B钢板 称为厚板，厚度＞60mm的Q345B钢板 则需在专门的特厚板轧机上轧制，故称特厚板。
The thickness of the Q345B plate is referred to as Q345B plate in thickness above 4mm, in actual work, often Q345B steel plate with thickness less than 20mm is called plate, plate thickness more than Q345B 20mm to 60mm called plate, plate thickness more than Q345B 60mm is rolling in the thick plate rolling mill special, so special plate.
厚Q345B钢板 的宽度从0.6mm-3.0mm。厚板按用途又分造船Q345B钢板 、桥梁Q345B钢板 、锅炉Q345B钢板 、高压容器Q345B钢板 、花纹Q345B钢板 、汽车Q345B钢板 、装甲Q345B钢板 和复合Q345B钢板等。汽车Q345B钢板 、装甲Q345B钢板 和复合Q345B钢板等。
The width of thick Q345B steel plate from 0.6mm-3.0mm. Thick plate by the use of sub shipbuilding Q345B steel, bridge Q345B steel, boiler Q345B steel, high pressure vessel Q345B steel, pattern Q345B steel, automotive Q345B steel, armored Q345B steel and composite Q345B steel plate, etc.. Automobile Q345B steel plate, armored Q345B steel plate and composite Q345B steel plate, etc..
