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 QT steel plate 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.
Both parties shall confirm the A514 grade P QT steel plate material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the A514 grade P QT steel plate steel plant.
Standing at a new historical starting point, we adapt to the requirements of supply side A514 grade P QT steel plate structural reform, adhere to the overall strategy of "innovation driven, quality leading, quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the International leading A514 grade P QT steel plate steel materials supplier.
High strength steel is mainly used in offshore engineering, lifting equipment, construction machinery, container storage tank and other important steel structures with harsh working conditions, hoping to reduce weight. The application of A514 grade P QT steel plate, high strength steel can not only reduce material cost, transportation cost and production cost, but also save welding material consumption, welding work hour; reduce post welding stress, preheating temperature and post weld heat treatment requirements.
