09CuPCrNi-A Weathering Steel

Cold rolled sheet 09CuPCrNi-A is equivalent to Q345GNHL.

09CuPCrNiA weathering steel plate is a kind of weathering steel (ie, atmospheric corrosion-resistant steel), used in sulfur-containing flue gas, air preheater, economizer, air preheater of boiler, preventing acid dew point, etc. Low-temperature weathering steel has strong resistance to low-temperature corrosion.

09CuPCrNi-A weathering steel manufacturing process:
09CuPCrNi-A weathering steel generally adopts the process route of fine material feeding into the furnace - smelting (converter, electric furnace - microalloying treatment - argon blowing - LF refining - low superheat continuous casting (feeding rare earth wire) - controlled rolling and controlled cooling. During smelting, scrap steel is added to the furnace together with the charge, and smelted according to the conventional process. After tapping, the deoxidizer and alloy are added. After the molten steel is treated with argon blowing, it is immediately cast. blank.
Due to the addition of rare earth elements to the steel, the weathering steel is purified and the inclusion content is greatly reduced.
