S355K2 steel material vs A283 Grade C

Steel is the main raw material for shipbuilding and marine engineering structure construction, accounting for 20% ~ 30% of the construction cost of hull and marine engineering. The steel S355K2 steel material products involved mainly include steel plates and section steel (marine bulb flat steel, H-beam, angle steel, etc.), casting and forging steel and supporting welding materials, etc. Among them, the amount of steel consumed for hull construction accounts for about 60% of the total ship mass, and sheet metal accounts for about 88%.

The S355K2 steel material plate products have passed the EU CE certification, and have been recognized by China, France, the United States, the United Kingdom, Germany, Italy, Japan, South Korea and other eight classification societies for high-strength ship plates. The steel strand products have passed the United States (PTI) certification. The S355K2 steel material products enjoy a high reputation in the domestic and foreign markets. The products are applied to national key projects and sold to 37 countries and regions such as EU, Middle East, Southeast Asia and America.

Semi-endless rolling technology has three advantages: the S355K2 steel material product's limit thickness and limit width specification range has been significantly expanded. The thinnest thickness of SPHC steel has been expanded from 1.0 mm to 0.78 mm, and the limit specification product width has been expanded from 1100 mm to 1300 mm; The thinnest thickness of Q235B steel has been expanded from 1.2 mm to 1.0 mm, and the width range of the limit specification products has also been further expanded.

Sulfur is a very harmful element in {keyword steel. The presence of sulfur will increase the hot brittleness of steel, reduce the various mechanical properties of {keyword steel, and reduce the weldability, impact toughness, fatigue resistance and corrosion resistance of steel.
