Welding is mainly used for manufacturing metal structure parts, and also for manufacturing machine parts. The welding connection performance is good, and it is convenient to weld A514 grade C alloy steel plate steel plates, profiles or castings and forgings according to the needs. At the same time, welding can also connect different shapes and sizes (plate thickness, pipe diameter) or even different materials, so as to reduce weight, save materials, optimize resources and other purposes. The welding structure has high rigidity, good integrity, and easy to ensure air tightness and water tightness, so it is especially suitable for A514 grade C alloy steel plate manufacturing hollow structures with high strength and large rigidity (such as pressure vessels, pipes, boilers, etc.).
EN10025-6 S690 steel is a quenched and tempered high-strength non-alloy steel plate. The series of grades are S690Q, S690QL, and S690QL1. They are in accordance with the European standard EN10025-6. The steel specified in this standard can be used for the production of hot-rolled plates with steel grades A514 grade C alloy steel plate, S460, S500, S550, S620, S690, S890, S960 series steel plates with a minimum nominal thickness of 3mm and a maximum nominal thickness of ≤150mm.
The company adheres to the business philosophy of "excellent quality and integrity", aims to create a first-class enterprise in the A514 grade C alloy steel plate industry, takes circular economy and resource reuse as the main line, takes energy conservation, emission reduction and sustainable development as the purpose, relies on advanced equipment, perfect transportation infrastructure and good reputation, and strives to become a leading enterprise in the A514 grade C alloy steel plate industry with scientific management, high quality, first-class service and harmonious development
The large diameter cold drawn seamless steel pipe is a steel pipe with an outer diameter of more than 1000mm. The large diameter seamless steel pipe is made of steel ingot or solid billet through perforation and then hot rolling, cold rolling or cold drawing. If they are long, they need to remove the redundant parts, that is, cut them out. Their length A514 grade C alloy steel plate is suitable for the length required by the construction of steel pipes.
