09CuPCrNi-A weathering steel characteristics and applications

09CuPCrNi-A is a kind of high-strength weathering steel, which belongs to a kind of atmospheric corrosion resistant steel. It forms a special steel with excellent weather resistance by adding a small amount of alloying elements such as copper (Cu), phosphorus (P), chromium (Cr) and nickel (Ni) on the basis of ordinary low carbon steel (such as Q235 steel). This steel can be used in the atmosphere for a long time without being damaged by corrosion, and has similar corrosion resistance and good durability to stainless steel.

09CuPCrNi-A characteristics

Strong corrosion resistance: due to the inclusion of copper, chromium, nickel and other alloying elements, 09CUPcrNIA can effectively resist the corrosion of atmosphere, seawater and other environments, and its weather resistance is 2 to 8 times that of ordinary carbon steel.

Good wear resistance: the steel has a certain hardness and toughness, and can effectively resist wear and impact.

Good weldability: 09CuPCrNi-A steel has good weldability, easy to process and use.

Strong oxidation resistance: the steel can effectively resist oxidation, has good high temperature resistance, can be used for a long time in a high temperature environment.

Long service life: due to its corrosion resistance, wear resistance, high temperature resistance and other properties, the service life of 09CUPCRNIa steel is longer than ordinary steel, and the service life is 8 times that of ordinary steel without any anti-corrosion treatment, and it can be used for more than 30 years in the case of the use of anti-rust paint.

09CuPCrNi-A application range

09CuPCrNi-A steel is widely used in many fields because of its excellent properties, mainly including:

Bridge construction: used to manufacture the main structure of the bridge, support structure and other components, with good durability and corrosion resistance, can effectively extend the service life of the bridge.

Construction field: Used to manufacture building exterior walls, roofs, Windows and other components, its red or brown surface after natural oxidation, can show a unique aesthetic effect, but also has good wind, rain, fire performance.

Vehicle manufacturing: Used to manufacture vehicle chassis, shell and other components, reduce maintenance costs and improve service life.

Shipbuilding: It is also used in the field of shipbuilding, especially in components that need to be resistant to seawater corrosion.

Petrochemical equipment: used to manufacture containers and other structural parts containing hydrogen sulfide corrosive media in chemical petroleum equipment to meet the corrosion resistance needs in specific environments.
