Carbon And Low-Alloy High-Strength Steel Plate

Carbon Steel, main point is that the mass fraction of carbon is less than 2.11% and does not contain the alloy elements and are specially added. Low-alloy high-strength steel is a kind of engineering structural steel developed by adding a small amount of Mn, Si and trace elements such as Nb, V, Ti and Al in the basis of Carbon structural steel.
The so-called low alloy is that the total alloy elements in the steel do not exceed 3%, which are mainly used for manufacturing various engineering structures with high strength, such as bridges, ships, vehicles, high pressure vessels, oil and gas transmission pipelines, large steel structures and so on.
Carbon steel plate and low alloy high strength steel plate, is the most common and widely used steel plate, strong supply capacity, the domestic production of the largest steel plate, we can cut processing according to customer requirements, and also can be processed according to the requirements of the drawings by grinder, our finished products are praised by our many customers, welcome to send us the enquiries and the drawing.

Shipbuilding Or Offshore Structural Steel Plate

Marine steel plate refers to the hot rolled steel plate used to manufacture the hull structure according to the standard requirements of the Classification Society. Shipbuilding or Offshore structural steel plate, first, good toughness is the most critical requirement. In addition, it requires high strength, good corrosion resistance, welding performance, processing performance and surface quality. In order to ensure quality and ensure enough toughness, the chemical composition of Mn/C is above 2.5, and the carbon equivalent is also strictly required, and it is produced by a steel factory approved by the Ship Inspection Department. With the development of marine industry, the steel demand is rising dramatically, in addition to the ordinary ship plate, offshore platform steel plate in recent years is the demanded for a wide range. Our Steel's EN10225 standard steel plate, get the praise of our many customers, including S355G7, S355G8.
