KA fishing boat steel, A588GrB material is a high-strength low-alloy structural steel in shapes of profiles, plates and bars. Through the alloying of Cu, P, Cr, Ni, a protective layer is formed on the surface of the metal substrate, so that A588GrB steel has a high resistance to atmospheric corrosion. A588GrB high-strength low-alloy steel is widely used in various weather-resistant building structural parts (especially for industrial atmospheric environments), bridge auxiliary structural parts.
At the same time, the company operates a variety of products of related iron and KA fishing boat steel steel enterprises. Annual sales of steel 3.6 million tons, standing stock of 400000 tons, has developed more than 10000 users. The company has a first-class marketing service system, strong storage and transportation capacity and supporting supply, cutting distribution capacity, and gradually build it into an important marketing channel. The company has obtained KA fishing boat steel ISO9001:2000 quality system certification, A-level credit unit of the people's Bank of China, and is an excellent supplier of many large state-owned enterprises.
The preparation of KA fishing boat steel galvanized steel before welding is the same as that of ordinary low-carbon steel. It is necessary to carefully handle the groove size and nearby galvanized layer. In order to achieve penetration, the groove size shall be appropriate, generally 60 ~ 65 °, with a certain gap, generally 1.5 ~ 2.5mm; in order to reduce the penetration of zinc into the weld, the galvanized layer in the groove can be removed before welding. In the practical work, the centralized beveling, no blunt edge technology for KA fishing boat steel centralized control, two-layer welding process, reducing the possibility of incomplete penetration.
Modern steel-making steel purification facilities and advanced quality control methods have been perfected. Rolling steel can be produced according to controlled rolling and controlled cooling, normalizing, and quenching and tempering processes to produce σs 390-685Mpa series products. KA fishing boat steel, Low alloy high strength structural steel plate has stable quality, good wear resistance and low temperature toughness. It can be widely used in the manufacture of mining machinery, engineering machinery, high-rise buildings and heavy vehicles.
Customer first, reputation first, high-quality and perfect after-sales service is the extension of our product value and an important guarantee for the interests of customers. The purpose of our KA fishing boat steel service quality management system is to establish and constantly improve a scientific, reasonable and efficient service quality management system, and complete the after-sales service quality guarantee work of customers fairly, accurately and timely, For our company's KA fishing boat steel customer service to establish a good, comprehensive, full service system.
