The steel plate for hull structure is also called marine plate or shipbuilding steel. Due to the harsh working environment of the ship, the hull shell is subject to the chemical corrosion of seawater, so the requirements for steel for the hull structure are strict. First of all, good toughness for marine plate S420M steelis the most critical requirement. In addition, it requires higher strength, good corrosion resistance, welding performance, processing performance and surface quality.

There are many kinds of heat treatment processes for wear-resistant composite plate, S420M steel, and they are applicable to different ranges. For example, direct quenching and low-temperature tempering can not refine the grain size of steel, the quenching deformation of workpiece is large, and the surface residual austenite volume of carburized parts of hardfacing wear-resistant composite plate is more, and the surface hardness is lower. It is suitable for gas carburizing and liquid carburizing.

LSAW Pipe to Peru. In the beginning of 2014, Peru government released an international tender for one of the hydroelectric power plant. Finally they chose us as the contractor, we purchased the steel plate and then fabricate the S420M steel steel plate into steel pipe, and then make the corrosion protect on the surface, we also supply the fitting with our steel plate, the total value of this order is about 2 million USD.
