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.
Under the rust treatment, the surface of the SPA-C steel plate has a rough surface feel, which makes the structure thicker and more textured, sublimates the visual and sensory effects, rapidly improves the effect of garden design, and improves economic an
As we know, SPA-C weathering steel sheet is usually resistant to corrosion. SPA-C weathering steel sheet is very necessary for the corrosion surface treatment. It can not only extend the service life of SPA-C weathering steel sheet, but also realize the s
The principle of weather resistance of A588 Grade A steel plate: After adding phosphorus, copper, chromium, nickel and other weathering elements to the steel, the A588 Grade A steel plate forms a dense and highly adherent oxide layer between the rust laye
