The iron oxide skin on surface of 09CuPCrNi-A curtain wall steel

Customer service center has provided after-sales service for many large-scale information systems, and has accumulated rich working experience in the process of 09CuPCrNi-A curtain wall steel service for many years. It can provide accurate, timely and high-quality support and service for users, which is well received by users.

ASTM A285 steel can be made into a variety of steel product forms, such as steel plates, 09CuPCrNi-A curtain wall steel steel coils, and steel pipes. It has good welding ability and can be used for fusion welding required by pressure vessel equipment. Its maximum thickness is limited to 09CuPCrNi-A curtain wall steel 50mm to ensure its mechanical properties.

The Performance requirements of low alloy structural steel, 09CuPCrNi-A curtain wall steel:(1) High strength: generally, the yield strength is above 300Mpa.(2) High toughness: the elongation is required to be 15% - 20%, and the room temperature impact toughness is greater than 600kJ/m ~ 800kJ/m. For large welded components, higher fracture toughness is required.(3) Good weldability and cold forming property.(4) Low cold brittle transition temperature. (5) Good corrosion resistance.

X-rays or γ-rays are projected on the surface of the steel plate, and rubber can be placed on the other side of the steel plate. Since the radiation propagates through the steel plate and is absorbed, the intensity is different due to the presence or absence of defects, so the film can record the shape and position of the defects. This 09CuPCrNi-A curtain wall steel method is sensitive to the detection of common steel plate defects such as slag inclusions, porosity and pores. The disadvantage is that it is difficult to find the specific depth of the defect and it is not easy to find cracks.

The company is mainly engaged in 09CuPCrNi-A curtain wall steel steel plates manufacturing and deep processing, sales and distribution. It is committed to building a complete modern steel purchase and sale network. Here we would like to express our sincere gratitude to our old and new friends who have always given care, support, affirmation and help, and sincerely hope to establish a long-term cooperative relationship with them for mutual benefit, win-win and common development, and work 09CuPCrNi-A curtain wall steel together for a better tomorrow.

Our company has a strong, professional R & D team and advanced and perfect sales service concept, which makes our 09CuPCrNi-A curtain wall steel products have a high visibility and market share at home and abroad. At the same time, we will always bear the principle of "credit first, customer first", always put the interests of customers first, and wholeheartedly provide each of our customers with the best products and services.
