What tests need to go through in the nm300 plate chemical composition production process
Temperature has a great influence on the strength of the material, nm300 plate chemical composition. When the temperature exceeds a certain value, the strength limit of the steel will be reduced. The higher the temperature, the lower the strength. In addition, the longer the steel is used at high temperature, the lower the strength. Therefore, if the steel works at high temperature for a long time, the instantaneous strength of the steel can not be used as its performance index, nor can the room temperature performance replace the high temperature performance.
BBN Group's first blast furnace blast dehumidification system: The project started construction on May 2 and began trial operation on August 28. All data are balanced and stable, blast furnace output indicators have improved significantly, and the daily dehydration capacity of the two blast furnaces is as high as 124 tons, with a daily increase of about 200 tons nm300 plate chemical composition, and the blast furnace is running smoothly.
If customers have any difficult problems during use of the steel materials, they can contact the company's after-sales service department to feedback the existing problems. The after-sales department will reply as soon as possible to ensure that each customer has a good after-sales experience. Under special circumstances, the after-sales service department will start the problem-solving process, and the engineers in charge of the area will quickly follow up to solve the problem.
nm300 plate chemical composition, NM400 wear resistant plate is a special structural steel with high wear resistance. Generally speaking, the higher the hardness is, the higher the wear resistance is. The average hardness of NM400 wear resistant plate is 400HB. After quenching, NM400 wear resistant plate has a good martensite bainite microstructure. The addition of Mo, Ni and B alloy ensures the uniform texture in the whole thickness direction.
