What is the Corten A building material extrusion technology

With the development of China's Corten A building material market economy, the company vigorously implements the strategy of industrialization, internationalization and diversification, promotes group operation, intensive development and lean management, and builds the company into a company with scientific development concept, continuous innovation vitality, excellent corporate culture and strong sense of social responsibility through rich series of Corten A building material products and project portfolio and complete operation network And international first-class competitiveness of modern enterprises.

SA387 Gr 11 Cl 1 steel has high brittle resistance, and also has good impact toughness in low temperature environments. It is suitable for refining and gas treatment in hydrogenation reaction and conversion equipment at high temperature. The maximum thickness of Corten A building material products can reach 250mm. According to different thickness and impact requirements, the heat treatment of A387 Gr 11 Cl 1 plate can choose normalizing and tempering or normalizing and rapid cooling and tempering.

With the development of science, technology and industry, higher requirements are put forward for steel materials, such as higher strength, resistance to high temperature, high pressure, low temperature, corrosion resistance, abrasion, and other special physical and chemical properties. Corten A building material, carbon steel can no longer fully meet the requirements, so alloy steel plates appeared. Improving the strength of steel is one of the main purposes of adding alloying elements.

Q355GNHE corten steel is characterized by adding a small amount of Cu, P, Cr, Ni and other alloying elements to the steel, so that the steel material forms a dense layer between the rust layer and the substrate with a thickness of about 50 to 100 μm and good adhesion to the substrate metal. The amorphous spinel oxide layer prevents oxygen and water in the atmosphere from penetrating into the steel substrate, slows down the rust development to the steel material, Corten A building material, and greatly improves the steel material's resistance to atmospheric corrosion.

S355J2 steel plate belongs to European standard low alloy steel, the executive standard is EN10025-2. Delivery status: normalizing, hot rolling or control rolling. S355J2 corresponds to the Chinese Q345D, but the executive standard is different, the chemical composition is slightly different, but their mechanical properties are the same. S355J2 low alloy steel plate tensile strength (MPA): 450-680, impact value: - 20 ℃: ≥ 27J. Corten A building material, S355J2 low alloy steel plate is widely used in bridges, vehicles, ships, buildings, steel structures, etc.
