China A387 gr 5 pressure vessel steel sheet production and operation maintained stable

A387 gr 5 pressure vessel steel sheet, VL E460 steel plate is a kind of structural steel plate for ship and ocean engineering. "VL" stands for the abbreviation of "DNV-GL", which is a standard jointly certified by DNV (Norway) and GL (Germany), "E" means the grade of steel plate is E, and "460" means the min. yield of VL E460 steel plate is 460 Mpa. The delivery status of VL E460 steel plate: TM (thermo mechanical control rolling), QT (quenching + tempering), TM + T (thermo mechanical control rolling + tempering).

The company has always put service and quality first, offered reasonable price, taken small profits and quick turnover as the principle, honest and trustworthy as the purpose. The success of the company is not only the hard work and wisdom of all the employees of the company, but also the deep love of our customers. We will continue to achieve new leaps and create greater brilliance of the A387 gr 5 pressure vessel steel sheet enterprise, and make our own contribution to the development of the world economy.

The effect of nitrogen (N) on the properties of A387 gr 5 pressure vessel steel sheet and so on steel is similar to that of carbon and phosphorus. With the increase of nitrogen content, the strength of steel can be significantly improved, especially the plasticity, especially toughness, and the weldability will be decreased, and the cold brittleness will be intensified. At the same time, aging tendency, cold brittleness and hot brittleness will be increased, which will damage the weldability and cold bending property of steel. Therefore, the nitrogen content in A387 gr 5 pressure vessel steel sheet and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.
