The company adopts modern management concept, adheres to “quality for survival, integrity for development”, and provides customers with high-quality and reliable EN S460ML steel steel products and wholehearted service. The company continuously deepens the internal reform of the enterprise, innovates in the reform, develops in the innovation, and gradually forms a set of management and operation mechanism which adapts to the market and has strong competitiveness.

S355NL normalized steel has different impact energy requirement for impact tests at different temperature environment. S355NL plate shall be done impacting test in longitudinal direction under -50℃ with the minimum energy 27J. When customers request done charpy_V notch test under -20℃, then the impacting energy shall be above 47J. For the transverse direction, the engery shall be above 16J under the temperature -50℃. The EN S460ML steel, steel Grade S355NL making process shall according to EN10025-1.

The main reference for structural design of steel structure engineering is the static and dynamic characteristics of the steel used under various actions, such as elasticity, plasticity, strength, toughness, fatigue and other mechanical properties. Therefore, the EN S460ML steel and so on steel used in the construction of steel structure engineering will limit its strength, plasticity, impact toughness and weldability. Steel structure engineering requires high tensile strength and yield point of steel. High yield point can reduce the cross-section of the component, so as to reduce the weight, save steel and reduce the cost. High tensile strength can increase the safety of the structure.

BBN Steel Company adheres to the marketing concept of "first-class technology, first-class steel quality, and first-class logistics services". It is our goal to build high-quality carbon steel EN S460ML steel, alloy steel plates and high-strength structural steel plate international-class boutique bases. Our logistic team will make customs clearance documents, track products production process, and update shipping information for customers. Creating value for customers is our pursuit.
