xar 400 steel material PVQ steel plate

API 5L X70 pipeline steel belongs to ultra-low carbon microalloyed steel. The production of API 5L X70 pipeline steel has almost applied all the new technological achievements in the field of metallurgy for more than 20 years. API 5L X70 pipeline steel is a product with high technology content and high added value. API 5L X70 hot rolled xar 400 steel material high strength pipeline steel is one of the important products in pipeline steel, which requires high precision of hot rolling equipment and difficult process control.

Since it was established in 2000. Based on the domestic rich xar 400 steel material product resources and the great steel demand of the international market, our xar 400 steel material service has already spread many countries in Europe , America, Southeast Asia, Middle East, South America, Africa, etc, and we have won an outstanding reputation for its professional exporting steel products

Primary processing, steel plate cutting processing cutting method, it is a flame cutting, because it to the accuracy requirement of the cutting size is not very high, the thickness of the xar 400 steel material plates in a certain range can be a good cutting quality and cutting effect, and the cut surface can be very smooth, however, it is important to note that in this work, is the need to pay attention to steel plate deformation at high temperature.

Due to the existence of this dense oxide film, the infiltration of oxygen and water into the steel matrix in the atmosphere is prevented, the development of corrosion into steel material is slowed down, and the atmospheric corrosion resistance of steel material is greatly improved. xar 400 steel material, Weathering steel is a kind of steel system which can be used thinly, exposed or simply painted, and make products resistant to corrosion, prolong life, save labor and reduce consumption, upgrade and replace.

Through the operation and management, brand advantage and improve pre-sales, sale of after-sales service, the efforts of the company into the industry leading enterprises.Relying on perfect quality management system, it has built up competition predominance and provided high quality, favorable price and perfect after service for customers.
