What is the anti-rust steel grade SMA490BW surface treatment

Focusing on the energy conservation and emission reduction objectives proposed by the municipal government, the company gives full play to the advantages of anti-rust steel grade SMA490BW circular economy formed after the comprehensive completion and operation, and vigorously promotes the implementation of energy conservation objectives. Through measures such as energy saving, technological innovation and anti-rust steel grade SMA490BW management strengthening, the energy saving target of annual reduction of added value energy consumption by 7%. It has made great contribution to energy saving of over completion.

Q345 steel has good comprehensive mechanical properties, acceptable low temperature performance, good plasticity and weldability. Q345 steel is used to make mechanical parts, building structures, general metal structural parts for medium and low pressure containers, oil tanks, vehicles, cranes, mining machinery, power stations, bridges and other structures that bear dynamic loads. anti-rust steel grade SMA490BW It is used in hot rolled or normalized state. In addition, Q345 steel is also widely used in construction, bridges, vehicles, ships, pressure vessels, etc.

anti-rust steel grade SMA490BW, Q345B low alloy plate performance:
1) High strength: Generally its yield strength is above 300MPa;
2) High toughness: The elongation is required to be 15% to 20%, and the room temperature impact toughness is greater than 600kJ/m to 800kJ/m. For large welded components, higher fracture toughness is also required;
3) Good welding performance and cold forming performance;
4) Low cold brittle transition temperature;
5) Good corrosion resistance.

anti-rust steel grade SMA490BW, Wear-resistant steel plates are composed of two parts, namely carbon steel plate and alloy wear-resistant layer. Under normal circumstances, the thickness of the alloy wear-resistant layer of the wear-resistant steel plate is 1/3-1/2 of the total thickness. When working, the matrix provides comprehensive properties such as strength, toughness and plasticity against external forces. And the alloy wear-resistant layer provides wear-resistant properties to meet the requirements of specified working conditions.

10 to 20mm thick anti-rust steel grade SMA490BW product: 10*2200*7200, 10*2200*8000, 12*2000*11850, 12.5*2900*11000, 12.9*2987*10384, 13.6*2940*11455, 14*2000*10000, 14*2000*11181, 14*2000*13500, 14*2070*9060, 14*2200*10030, 15*2200*10270, 15*2500*10000, 15*2992*10185, 16*1500*9340, 16*1800*6000, 16*2000*10713, 16*2120*6080, 16*2200*10000, 16*2230*7650, 18.5*2320*6600, 20*1400*11400, 20*2100*7000.

For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate anti-rust steel grade SMA490BW EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.
