Q355NH weathering steel plate quickly forms a stable rust red oxide film, with uniform color and thickness, and is not easy to wipe off. Generally, the rust removal process is completed within 3 hours at an outdoor temperature of 25 degrees Celsius.
Q235NH weathering steel is characterized in that the alloy composition and weight percentage content of weathering steel are: carbon: 0.12, silicon: 0.25-0.75, manganese: 0.2-0.5, sulfur 0.02, phosphorus: 0.06-0.12, copper: 0.25-0.5, Chromium: through all
Q345NH weathering steel plate is a new type of alloy raw material. The reason is that copper, nickel, chromium, phosphorus and other components are added to Q345NH weathering steel plate to change the growth of the rust layer from the original sheet-like
S235J2W steel plate is an enhanced atmospheric corrosion resistant steel plate, which is a European standard steel plate. S235J2W steel plate implements the EN10025-5 standard, and the corresponding number in the EN10027-2 standard is 1.8961.
To distinguish the authenticity of EN10025-5 S235J2W weathering steel plate, we must first understand the rusting process of weathering steel and ordinary steel. The following can clearly reflect the difference between ordinary steel plate and EN10025-5 S
Weathering steel plate thickness is usually 1.5mm~4mm, medium plate thickness is 4mm~20mm, thick plate is 20mm~60mm, extra-thick plate can reach 80mm, and width is conventional 0.5m, 1m, 1.2m, 1.5mm, 2m and so on. (Different manufacturers have their own d
Rust stabilization treatment method for S355K2G1W weathering steel: The rust stabilization treatment method uses a chemical method (rust liquid) to slowly melt the surface film of the S355K2G1W weathering steel to produce rust stability and form a uniform
Unique performance characteristics of A709 grade 50W weathering steel plate: A709 grade 50W weathering steel plate has outstanding visual performance, and rusted steel will change over time. The color, brightness and saturation of A709 grade 50W weatherin
Ferritic stainless steel: 12% to 30% chromium. Its corrosion resistance, toughness and weldability increase with the increase of chromium content, and its resistance to chloride stress corrosion is better than other types of stainless steel.
EN 10155 S355J2G1W weathering steel plate is made by adding phosphorus, nickel, copper and other trace elements to the ordinary steel plate in the smelting process. Dense and highly protective film is formed on the steel surface, which hinders the further
