Its advantages are good flatness and high gloss of weathering steel plate after production and processing. Its defects are high labor efficiency, serious environmental pollution, and complex weather resistant steel plate can not be produced and processed,
After the surface of S355K2G2W weathering steel is heated and cooled, the metal heat treatment process of the surface properties changes. The performance of S355K2G2W weathering steel cannot be improved without heat treatment, and solution treatment is on
In order to achieve good practical results, BS4360 WR50A weathering steel plate must be cut and laser cut. Because the weathering board is durable and strong, it will inevitably take time in the case of laser cutting.
Add a small amount of copper, phosphorus, chromium, and nickel to the steel grades of high weather resistance structural steel to form a protective layer on the surface of the metal collective to improve the performance of atmospheric corrosion resistant
ASTM A588 Grade C weathering steel corrosion resistance: Many bridges are designed to be close to the water surface, and some are even cross-sea bridges. No matter whether it is sea water or river water, there will be high tide to some extent, which will
The base material of ASTM A 709 Gr.50W weathering steel plate is low carbon steel or low alloy. A tough material like stainless steel embodies the superiority of bimetal. The wear-resistant layer is resistant to media and abrasion, and the base material b
In today's society, JIS G3114 SMA 50 CP weathering steel plate can be seen everywhere. A large number of JIS G3114 SMA 50 CP weathering steel plate have been built and used in various industries. However, we usually see rusty weathering steel plates.
The cold galvanizing of SPA-C weathering steel sheet is electro-galvanized, and the amount of galvanizing is very small, only 10-50g/m2. Its corrosion resistance is very different from that of SPA-C weathering steel sheet hot-dip galvanizing.
Hot-dip galvanizing is to make the molten metal react with the iron matrix to form an alloy layer, so that the matrix and the coating are combined. The manufacture of SPA-C weathering steel plate processing is to pickle the weather-resistant steel plate t
The reason for the cracks of ASTM A242 Type1 steel plate is the strength, hydrogen efficiency, welding method and other factors. In fact, cracks are not easy to damage the wear resistance of ASTM A242 Type1 steel plate, and the quality of ASTM A242 Type1
