What is the use of material of 09CuPCrNi-A

Preheating cutting: The most effective way to prevent steel plate cutting cracks is to preheat before cutting. Before flame cutting, the steel plate is usually preheated, and the preheating temperature mainly depends on the quality level and thickness of the steel plate. The preheating method can be carried out with flame burner, electronic heating pad, or heating furnace. In order to determine the preheating effect of the steel plate, the required temperature should be tested at the heating point.

The effect of nitrogen (N) on the properties of material of 09CuPCrNi-A and so on steel is similar to that of carbon and phosphorus. With the increase of nitrogen content, the strength of steel can be significantly improved, especially the plasticity, especially toughness, and the weldability will be decreased, and the cold brittleness will be intensified. At the same time, aging tendency, cold brittleness and hot brittleness will be increased, which will damage the weldability and cold bending property of steel. Therefore, the nitrogen content in material of 09CuPCrNi-A and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.

For the material of 09CuPCrNi-A construction industry, the largest consumer sector of the steel industry and the least affected industry in the EU this year, it is estimated that material of 09CuPCrNi-A steel consumption will account for 35% of the EU steel consumption market this year. Uestf forecasts that the output of the construction industry will decline by 5.3% in 2020 and rise by 4% in 2021.

AR400 wear resistant steel is a special structural steel with high wear resistance. Generally speaking, the higher the hardness, the higher the wear resistance of the steel, material of 09CuPCrNi-A. The average hardness of AR400 wear-resistant special structural steel is 400HB. After quenching, AR400 wear resistant steel has good martensite bainite microstructure. The addition of Molybdenum (Mo), Nickel (Ni) and Boron (B) alloys ensures uniform texture in the whole thickness direction of AR400 wear resistant steel.
