China supply carbon steel EN 10025 S460QL1 high strength steel price

Q690D steel belongs to high-strength welded structural steel. Among them, Q represents the yield strength, 690 represents the yield strength value, and D represents the grade of the steel plate. The quality grades of common Q690 series steel are A, B, C, D, E. The impact of grade D steel plate is -20°C. Q690D steel can be called a low temperature resistant high strength steel with a yield strength of 690Mpa.

Rolling of steel plates is the core of the entire steel rolling production process. The billet is deformed by rolling. The rolling process plays a decisive role in product quality. The quality requirements of rolled EN 10025 S460QL1 high strength steel products include the three aspects of product geometry and dimensional accuracy, internal organization and performance, and product finish. Finishing: It is the last process in the EN 10025 S460QL1 high strength steel rolling process, and it is also a more complicated process. It plays a final role in guaranteeing the quality of the product.

Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of EN 10025 S460QL1 high strength steel etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in EN 10025 S460QL1 high strength steel etc. steel is strictly controlled.
