Development of 09CuPCrNi-A chemical composition in China

Heat treatment process: heat treatment refers to a kind of process operation in which the metal or alloy can change the internal structure through certain heating, heat preservation and cooling methods in the solid range to obtain the required performance. 09CuPCrNi-A chemical composition Heat treatment process refers to the ability to change the microstructure and properties of 09CuPCrNi-A chemical composition after heat treatment, including hardenability, hardenability, temper brittleness, etc.

Due to the existence of this dense oxide film, the infiltration of oxygen and water into the steel matrix in the atmosphere is prevented, the development of corrosion into steel material is slowed down, and the atmospheric corrosion resistance of steel material is greatly improved. 09CuPCrNi-A chemical composition, Weathering steel is a kind of steel system which can be used thinly, exposed or simply painted, and make products resistant to corrosion, prolong life, save labor and reduce consumption, upgrade and replace.

The technical characteristics of activated coke dry desulfurization and denitrification are as follows: (1) In view of the complex flue gas working conditions with sulfur, nitrogen, oxygen, high water content and large fluctuations produced by sintering, as well as working conditions with high requirements for removal efficiency and index stability, advanced two-stage activated coke drying Method purification technology; (2) In order to meet the ultra-low emission requirements of particulate matter, proprietary porous plate and microporous plate technology are adopted; (3) Activated coke feeding and unloading adopts advanced rotary sealing valve technology to reduce the powdering rate of activated coke and improve the sealing effect.
