The cutting speed has a parabolic relationship with the cut surface roughness of A 709 Grade 50W weathering steel plate. As the cutting speed decreases, the surface roughness of A 709 Grade 50W weathering steel plate increases rapidly. With the increase o
When the rolling thickness of ASTM Corten A steel plate is more than 10 mm in the rolling pit, after the wear-resistant liner bites into the rolling mill, the splint should be opened quickly to reduce the friction between the splint and the bimetallic AST
Q235NH weathering steel plate cracking causes and countermeasures, poor weldability, resulting in failure to weld; set appropriate welding conditions. Repair bad weldments, resulting in poor welding. Matters needing attention in the cutting process. Conta
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
