Q370q steel is a kind of bridge steel plate. It is delivered in hot rolled, normalized condition. There are three quality levels Q370qC, Q370qD, and Q370qE. Bridge steel Q370qC, Q370qD, A514 grade P structural steel and Q370qE steel plates have different impact temperatures: C represents 0℃, D represents -20 ℃, and E represents -40℃. Q370qC-Z25 steel plate can be hot-rolled and normalized heat-treated. When mechanical properties are required, large thickness must be normalized. The thickness of Q370q steel plate we supply is above 8mm.
What is the specific use of A514 grade P structural steel, hot rolled plate in daily life? First of all, hot rolled plate is used in bridge, vehicle structure, frame and other fields to play a role of bearing pressure. Secondly, high pressure boiler vessels are also made of hot rolled plates, which can be heat-resistant and airtight, and can stably seal the hot gas in the container. Thirdly, stainless steel hot rolled plate can be used to process hardware products. It has excellent corrosion resistance, and is easy for processing.
How to distinguish the inferior steel plate? 1. The surface of the fake and inferior steel plate is easy to produce scab. 2. The material of fake and inferior steel plate is not uniform and there are many impurities. The surface of fake and inferior steel plate is often pitted. Pitting is an irregular and uneven defect on the surface of A514 grade P structural steel, steel plate caused by serious wear of rolling groove. Due to the pursuit of profit by the manufacturers of fake and inferior steel plates, the groove rolling often exceeds the standard.
