1. Good weather resistance
In 09CuPCrNi-A steel, copper, chromium, nickel and other elements are added, and at the same time, the content of Si and P in the steel is controlled, which makes the steel have a good weather resistance. In the harsh external environment, it can resist oxidation and corrosion well, so it can be used for a long time.
2. Excellent mechanical properties
09CuPCrNi-A steel also has good performance in terms of mechanical properties. Its tensile strength is 435-490MPa, yield strength reaches 290-345MPa, and elongation at break can reach 22%. These are relatively excellent data.

3. Easy to process and weld
09CuPCrNi-A steel performs very well in machining and welding. It has excellent weldability and heat resistance, and is easy to machine due to its high plasticity and toughness.
4. Low maintenance cost
When using 09CuPCrNi-A material, its maintenance cost is very low. Due to its good weather resistance, it does not require much care and maintenance during use. In some occasions where the environment is extremely harsh, the use of this material can reduce the maintenance workload and save a lot of time and cost.
