What is the difference between q235b mild steel sheet and mild steel material

Therefore, on the premise of meeting the use requirements, q235b mild steel sheet carbon steel should be preferred. However, alloy steel should still be used for stainless steel parts with large size, complex shape, high strengthening performance and high precision, or parts with thermal hardness and other special properties.

q235b mild steel sheet, SN490 steel is one of the most widely used structural steel for building in contemporary society. Because of its special construction method requirements, it improves the "strength", "toughness" and "weldability", and has better shock resistance effect. SN490 steel is different from the earlier SS series and SM series steel. Because there is no provision for the yield strength or tensile strength, the strength of building materials may be too high, the problem of yield ratio and the lack of alloy elements make it difficult to control.

When talking about our team, it is hard not to mention our QC department (Quality Control). We have built strict qualitycontrol system to guarantee the steel quality. During the steel materials production, we have strict monitoring measures and indicators, and ensure no chemical composition, mechnical properties and so on technical problems for the steel materials q235b mild steel sheet. After production, our QC department will conduct another inspection regarding to the steel quantity, dimension, mark and so on points before delivery.

Under the action of the roller and the plug, a cavity is formed in the blank, which is called the blank. Then send it to the automatic tube rolling machine to continue rolling. Finally, the wall thickness of the whole machine is equalized and the diameter is calibrated by the sizing machine to meet the specification requirements. It is an advanced method to produce q235b mild steel sheet, hot-rolled seamless steel tube by continuous rolling mill.
