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
A588 Gr.A weathering steel plate adopts the lean production method of filtering and pouring thick steel slab + extrusion forming + cold rolling to obtain high-quality wear-resistant steel. It is a composite type of general carbon and nickel, chromium, mol
Crystal growth and thickening of SPA-C weathering steel plate. Depending on the composition of the metal material, the degree of roughening is also different. SPA-C weathering steel plate containing carbon, manganese, and phosphorus is easy to roughen, wh
Q235NH weathering steel plate full name: atmospheric corrosion-resistant hot-rolled steel, also known as Corden steel, corrosion-resistant steel, widely used in outdoor steel such as large outdoor sculpture steel such as containers, power plant chimneys,
On December 31, the latest price of hot-rolled weathering steel in the Shanghai market showed an upward trend. Among them, the price of 3.0*1250*C SPA-H hot-rolled weathering steel was 4,680 yuan per ton, an increase of 20 yuan per ton. Tons; the price of
Corten A weathering steel plate is a kind of steel, a type of steel plate that resists corrosion and wear resistance. For Corten A weathering steel plate, it is more to ensure the properties of weathering board, which is mostly used in many buildings. In
