Brief introduction of weathering steel 09CuPCrNi-A

09CuPCrNi-A steel belongs to low temperature weathering steel, 09CuPCrNi-A has strong resistance to low temperature corrosion.

Chemical composition of weathering steel 09CuPCrNi-A: C: ≤ 0.06, Si: ≤ 0.57, Mn: 0.48, P: 0.018, S: 0.013, Ni: 0.15, Cr: 0.47, Cu: 0.3.

The mechanical properties of weathering steel 09CuPCrNi-A:
Lower yield strength: 355MPa
Tensile strength: 490 - 630MPa
Elongation after fracture: ≥ 22%

Characteristics and application of weathering steel 09CuPCrNi-A:
Weathering steel 09CuPCrNi-A is generally used in air preheaters, sulfur-containing flue gas, economizers, boiler air preheaters, to prevent acid dew points and so on.

Weathering steel 09CuPCrNi-A has corrosion resistance. For example, when it is used on the exterior of a building, the facade of the building does not need to be painted with protective paint. Once the "rust film" is formed, it has 80 years of anti-corrosion effect, and 80 years does not need to be painted with protective paint.
