09CuPCrNi-A corten steel sheet properties

Corrosion resistance of 09CuPCrNi-A corten steel sheet
After adding phosphorus, copper, chromium, nickel and other trace elements to the 09CuPCrNi-A corten steel sheet, a dense and highly adherent protective film is formed on the surface of the steel, which hinders the spread and development of rust and protects the substrate under the rust layer to slow down its corrosion rate. The amorphous spinel-type oxide layer with a thickness of about 50μm-100μm formed between the rust layer and the substrate is dense and has good adhesion to the substrate metal. Due to the existence of this dense oxide film, it prevents oxygen and oxygen in the atmosphere. The penetration of water into the steel matrix slows down the in-depth development of corroded steel materials and greatly improves the atmospheric corrosion resistance of steel materials. Weathering steel is a steel series that can be used in thinner, exposed, or simplified coating, so that it can resist corrosion, extend life, save labor and reduce consumption, and upgrade. It is also a steel system that can be integrated into modern metallurgical new mechanisms, new technologies, and new processes to make it Continuous development and innovation of the steel series.
 
Surface of 09CuPCrNi-A corten steel sheet
There should be no delamination of the steel plate, and there should be no cracks, bubbles, scars, inclusions, or folds on the surface of the steel plate. If the above-mentioned defects on the surface are allowed to be removed, the depth of removal should not exceed half of the steel thickness tolerance, and the removal should be smooth and without edges.
 
09CuPCrNi-A corten steel sheet application range
09CuPCrNi-A corten steel sheet is outdoor steel for containers, power plant chimneys, railway projects, such as steel for large outdoor sculptures. Weathering steel (that is, atmospheric corrosion resistant steel) is a low-alloy steel series between ordinary steel and stainless steel at a low price and good quality.
