Cold rolled 09CuPCrNi-A weathering steel mechanical properties

The quality of carbon steel is distinguished by the amount of sulfur (s) and phosphorus (P) in the steel. When the 09CuPCrNi-A weathering steel sulfur content in carbon steel is not more than 0.050% and the phosphorus content is not more than 0.045%, it is ordinary carbon steel; when the sulfur content and phosphorus content in carbon steel are less than 0.040%, it is high-quality carbon steel; when the 09CuPCrNi-A weathering steel sulfur content in carbon steel is less than 0.030% and the phosphorus content is less than 0.035%, it is high-quality carbon steel.

Try to use 09CuPCrNi-A weathering steel high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the 09CuPCrNi-A weathering steel temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.

Alloy steel plate: The primary purpose of adding alloy elements to steel is to improve the hardenability of the steel, and it is easy to obtain martensite during quenching. The second is to improve the tempering stability of the steel to keep the martensite at a higher temperature, so that the carbides precipitated during the tempering of the quenched steel are smaller, uniform and stable. In this way, under the same conditions, alloy steel has higher strength than carbon steel, 09CuPCrNi-A weathering steel.

Our quality and service commitment: 09CuPCrNi-A weathering steel product quality problems, life-long replacement.In the process of using, any time if you find we supplied steel materials not conform to the requirements of technical standards, we can replace it for you free of charge.
