Q355GNH Z35 plate ASTM equivalent steel grade

BEBON cpompany practice new development concepts, expand in an all-round way, deepen reform and innovation, speed up transformation and upgrading, become stronger, better and bigger, accelerate the implementation of BEBON Steel's Q355GNH Z35 plate industrial planning, and realize the revitalization and development of enterprises.Fully implement the corporate Q355GNH Z35 plate market dominant position, comprehensively promote contractual management, and promote the transition from "internal production" to "market operation”.

The carbon Q355GNH Z35 plate content of the pipeline steel is required to be low, and the strength of the pipeline steel is ensured by increasing the manganese content and adding trace elements such as niobium, titanium, vanadium and molybdenum. For pipeline steel, in addition to the required strength and plasticity index, the requirement for toughness index is an outstanding feature, including the impact energy of pipeline steel plate, impact transition temperature and toughness index of welding heat affected zone and welding metal. In addition, there are requirements for strain aging, weldability, stress corrosion and other indicators.

It is easy to confuse ship plate with ordinary steel plate. What are the differences between ship plate and ordinary steel plate? First, compared with the ordinary steel plate, the thickness of the ship plate is thicker and the accuracy is better. Otherwise, it will be broken by the impact of sea water during the operation, which will bring life danger to the personnel on the ship. Second, compared with ordinary steel plate, Q355GNH Z35 plate, the corrosion resistance of ship plate is more outstanding. The ship is immersed in sea water for a long time, if it does not have good corrosion resistance, then the ship plate will rust easily, and the weight of the ship will become larger, and it will also bring pollution to the sea water and cause ecological damage.

The Q355GNH Z35 plate, heavy steel marine steel plate has the characteristics of pure steel, stable performance and good surface quality, and can be delivered at full scale. The marine steel plates are widely used in the construction of the main structure and superstructure of 10,000-ton ocean-going ships, and can also be used to manufacture the hull structure of inland ships. With the improvement of equipment level and the continuous progress of technology, heavy steel marine plate has made great progress in the production of high-strength shipbuilding steel plates, and its products are extending to the high-end market.
