The weather resistance of Q235NH weathering steel is 2 to 8 times that of ordinary carbon steel, and the coating property is 1.5 to 10 times that of ordinary carbon steel. Mainly used for steel structures exposed to the atmosphere for a long time, such as
Different from ordinary steel plate, A242 type1 weathering steel plate has good corrosion resistance. In the acid rain and other severe weather, many buildings began to appear different degrees of corrosion, which not only affects the buildings, but also
Quenching of Q345NH weathering steel plate is a kind of heat treatment to improve the overall hardness. However, there are many Q345NH weathering steel plate used to make mechanical parts that only require hard appearance but soft inside. Q345NH weatherin
The results show that copper is the most important factor affecting the weather resistance of JIS G3125 SPA-H steel plate, while nickel has little effect on it. Copper acts as an active cathode in JIS G3125 SPA-H steel plate.
The mechanical properties of Q355NH steel plate meet the technical requirements. Q355NH steel plate has high strength, low thickness effect, excellent low temperature impact performance and excellent welding joint performance.
GB/T 4171 Q355GNH weathering steel is widely used in Vehicle, Bridge, Tower, Container and so on fields. BBN is a professional GB/T 4171 Q355GNH weathering steel supplier in China. We have a large of GB/T 4171 Q355GNH weathering steel stock every month.
S355J2WP steel plate is under the European standard EN 10155 used for welding, bolted connection and riveting component. The component of S355J2WP steel plate has better atmospheric corrosion resistance. S355J2WP steel plate should not do the heat treatme
Corrosion is one of the main broken forms of the genus gold. The metal loss caused by corrosion is 10% of the total amount of gold in the world every year, among which the large gas corrosion is one of them.
Rust stabilization treatment is to use chemical method (rust liquid) on the surface of A242 type 1 weathering steel plate to make it produce rust stabilizing film. It is a kind of inhibiting rust flowing out of A242 type 1 weathering steel plate at the in
If ASTM A242 Type1 weather resistant steel plate is heated to a certain high temperature in the air during welding or grinding, chrome oxide heat return color will appear on both sides of the weld, the lower surface and the bottom of the weld.
