EN10025-5 05CuPCrNi Weathering Steel 

05CuPCrNi with oxygen in the air reacts at the surface to form a layer of dense oxide protective film; this oxide layer as a protective film which prevents corrosion of the steel layer of protection. This layer constantly renewed, and over time form.

Chemical Composition(%) and Mechanical Property:

Feature of 05CuPCrNi:

• Excellent weather resistance
• Long service life
• Environmental friendly
• Good performance of high mirror polishing
• Anti-acid, anti-rust after heat- treatment
• Good corrosion resistance
• Resistance for erosive attack
• Low deformation rate
• Good stability

Application of 05CuPCrNi :
Used in different weather. It has good anti rust protection and welding ability and is used in shipping container,support frame of outside building etc. Remarkably enhances the anti-corrosive performance of the structural element, lengthens the structural element service life, 05CuPCrNi Weather Resistant Steel coil is used in Vehicle, Bridge, Tower, Container And So On.

Heat Treatment of 05CuPCrNi:

• Hot Rolled
• CR, Normalized
• Quenched, Tempering
• TMCP
• lectroslag Remelting Technical

05CuPCrNi steel Specification:
Thickness: 6mm to 300mm
Width: 1500mm to 4050mm
Length: 3000mm to 15000mm
