Introdution of Anson Shipbuilding Steel Plate

Reducing weight and increasing energy efficiency have been prime concerns to achieve the large size ships such as ultra large crude oil carriers,very large crude oil carriers,liquefied gas carriers,cargo ships,and passenger carriers,while reducing construction cost and time also has been increasingly required in shipbuilding steel plate industry.Steel plates produced by thermo-mechanical control processes have provided an effective solution to those requirements,offering better combinations of strength and toughness without losing weldablity,as compared with conventional normalized steel plates.

shipbuilding plate

The use of the shipbuilding steel plates with higher strength has made it possible not only to reduce the weight of the ship but also to apply high speed,high heat input welding to the construction because of better weldability and toughness.Being combined with shipbuilding steel plate,a variety of welding technologies have also been developed to increase welding speed,deposition rate and integrity of welds.

More recently,concerns have been extended to the safety and duability of ships,and thereby,improved toughness,crack arrestablity,corrosion resistance and fatigue strength have been demanded for structural steel plates for shipbuilding.

Anson brand shipbuilding steel plate will be your right steel for your shipbuilding industry.
