What is the s355j2 steel number continuous casting

The s355j2 steel number 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 s355j2 steel number 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.

S50C steel characteristics: the carbon content of the steel (mass fraction, %) ≥ 0.4, excellent wear resistance, reduced ductility, easy to deform and crack after quenching, so quenching is extremely important, and it must be quenched after cutting and tempering to avoid tempering brittleness. By implementing spheroidizing treatment, the cutting performance of this type of carbon steel keyword} can be improved. The steel is usually used after tempering to a hardness of 19~22HRC to increase its cutting performance.

The wear-resistant plate s355j2 steel number shows good wear resistance: the chemical composition of the alloy layer contains 4-5% carbon and 25-30% chromium. The volume fraction of Cr7C3 carbide in the metallographic structure is more than 50%, the macro hardness is HRC56-62, and the hardness of chromium carbide is HV1400-1800. Because of the vertical distribution of carbides in the wear direction, the wear resistance of the cast alloy with the same composition and s355j2 steel number hardness is more than twice as that of the cast alloy with the same composition and hardness. Compared with several typical materials, the wear resistance is as follows: (1) compared with low carbon steel; 20-25:1 (2) with as cast high chromium cast iron; 1.5-2.5:1.

Low alloy high strength steel plate is made by adding a small amount of alloy elements on the basis of carbon structural steel (carbon content 0.16% ~ 0.2%). s355j2 steel number, Low alloy high strength steel plate has good welding performance, plasticity, toughness and processing technology, good corrosion resistance, high strength and low critical transition temperature of cold embrittlement.

A131 EH36 steel is high strength marine grade hull structural steel. Its yield strength is no less than 355Mpa, tensile strength is 490-620 Mpa, and elongation is 19% min. s355j2 steel number, EH36 steel strength is close to S355 steel. However, EH36 steel is shipbuilding steel, while S355 steel is carbon structural steel, and can not be certified by classification society. That is to say, S355 steel is not allowed to be used for ship building when there is certificate requirement. A131 EH36 steel is widely used to build ships working in low temperature water.

The company will rely on its good reputation, excellent hot-rolled plates, steel pipes, steel structure products, and intimate s355j2 steel number after-sales service to customers. I would like to express my heartfelt thanks to the old and new friends and customers who have always given care, support and help to the company! The company sincerely hopes to establish a long-term cooperative relationship with them, mutual benefit and common development. Welcome to come and visit our s355j2 steel number steel mill.
