pipe S690QL Vs A 36 Steel

Corrosion-resistant steel plate significantly improves the corrosion resistance of structural parts and prolongs the service life of structural parts. It can be used to make various structural parts that work in atmospheric environments and corrosive gases and liquids. Plate pipe S690QL delivery status: According to performance and user needs, steel plates can be delivered in hot rolling, controlled rolling, normalizing, annealing, tempering, normalizing + tempering, quenching and tempering.

Our company was founded in 2000, which initially committed to providing high-quality steel pipe S690QL products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export pipe S690QL steel to the international market, opening up the international steel market.

The user of S355NC grade must make sure that his calculation, design and processing methods are appropriate for the pipe S690QL material. The forming process used must be suitable for the intended application and comply with the state-ofthe- art; it is of fundamental importance to the processing behaviour of this pipe S690QL steel grade.

Phosphorus is a very harmful element in pipe S690QL steel. With the increase of phosphorus content, the strength, flexion ratio and hardness of pipe S690QL steel increased, but the plasticity and toughness decreased significantly. In particular, the lower the temperature, the greater the impact on plasticity and toughness, increase the cold brittleness of steel.
