How to distinguish the normal floating rust and rusting of corten a steel density

Our company specializes in the production of steel plates, steel coil, steel sections, welded pipes and seamless pipes products, sales of GB, ASME, ASTM, JIS, DIN, EN, API and other standards and specifications of steel corten a steel density and deep-processed products, facing the domestic and foreign markets, welcome to call for inquiries. It is a modern high-tech professional enterprise integrating scientific research, production and sales.

Pressure vessel steel plate is mainly used for manufacturing pressure vessel or other similar equipment for gas separation and gas storage and transportation in petroleum and chemical industry. Generally, the working pressure of corten a steel density pressure vessel steel plate is 320kg / cm2 or 630kg / cm2 under normal pressure, and the temperature is within the range of - 20-450 ° C. It is required that the pressure vessel steel plate has not only certain strength and good plasticity and toughness, but also good cold bending and welding performance.

Stainless steel plate is a general term for stainless steel plate and acid-resistant steel plate, and is a steel plate with good corrosion resistance and rust resistance on the surface. The surface of corten a steel density, stainless steel plate is very smooth and clean. It has high toughness, plasticity, and is not easy to be corroded and rusted. Stainless steel plate has corrosion resistance and high temperature oxidation resistance. Stainless steel is durable, can be stored outdoors for a long time, and will not be damaged in bad weather. Stainless steel plate is not easy to rust, but it is not absolutely not rusty.

Corrosion resistance mechanism of corten a steel density, stainless steel: obvious Cr2O3 film is formed on the surface of stainless steel, and the minimum content of O and Cr (10.5%) is required to obtain continuous protective film to prevent corrosion. If the protective film is damaged, it can recover naturally.

DIN 17102 TStE285 steel plate/sheet, DIN 17102 TStE285 steel plate/sheet, under DIN standard, we can regard TStE285 steel plate/sheet as fine-grain structural steels, normalised rolled steels. corten a steel density, DIN 17102 TStE285 is mainly used as ine-grain structural steels, normalised rolled steels. corten a steel density, TStE285 steel plate/sheet is a hot rolled structural steels, which technical delivery conditions for normalized or normalized rolled in weldable fine grain structural steel grade. It is also regarded asEN10025:S275NL.UNE36081:AE285KT

The company's products corten a steel density have excellent quality, reasonable prices and strong usability, and are well received by users. Survive by quality, expand the market with integrity, continuously research and develop new products, expand varieties, to meet market demand, and make the company continue to grow. The needs and interests of users are our high philosophy of service and commitment, and customer satisfaction is our eternal pursuit.
