09CuPCrNi-A weather-resistant steel plate performance

09CuPCrNi-A weather-resistant steel plate performance

Cupcrni-a weathering steel plate is A kind of outdoor corrosion resistant engineering steel, belonging to ordinary low alloy steel, mainly used in railway, vehicles, Bridges, iron towers and other steel structures. This kind of steel plate is exposed to the atmosphere for a long time, and has the characteristics of rust prevention, corrosion prevention and life prolonging, thinning and consumption reduction, labor saving and energy saving.

09CuPCrNi-A weather-resistant steel plate characteristics

Weather resistance: Compared with ordinary carbon steel, the weather resistance of 09CuPCrNi-A weathering steel plate is 2-8 times that of ordinary carbon steel, and the coating performance is 1.5-10 times that of ordinary carbon steel.

Corrosion resistance: By coating a layer of corrosion-resistant alloy layer on the surface of the steel plate, 09CuPCrNi-A weathering steel plate has excellent corrosion resistance and can adapt to various harsh environmental conditions, such as Marine environment, industrial gases and so on.

Excellent mechanical properties: the steel plate has the characteristics of toughness, ductility, formability, weldability and cutting, wear resistance, high temperature resistance and fatigue resistance of high-quality steel.

09CuPCrNi-A weathering steel plate the main chemical components include:

Carbon (C) : ≤0.12%

Silicon (Si) : ≤0.80%

Manganese (Mn) : ≤1.20%

Phosphorus (P) : ≤0.15%

Sulfur (S) : ≤0.03%

Copper (Cu) : ≥0.25%

Chromium (Cr) : ≥0.30%

Nickel (Ni) : ≥0.30%

The content of these elements has a direct impact on the performance of 09CuPCrNi-A weathering steel plate. The combination of copper and phosphorus plays an important role in resisting atmospheric corrosion, while the addition of chromium and nickel improves the corrosion resistance and strength of the steel.

09CuPCrNi-A weather-resistant steel plate mechanical properties include:

Yield strength: about 275MPa

Tensile strength: about 390MPa

Elongation: About 31%

Hardness: About 150HB

09CuPCrNi-A weather resistant steel plate delivery status:

Delivered in hot-rolled or hot-rolled annealed condition.

Hot-rolled steel plates may be delivered after pickling upon agreement between the supply and demand parties.

When delivered in flat form, the four sides of the steel plate should be cut neatly and at right angles.
