Hot rolled plate hardox 400 steel yield strength Malaysia
Hot-rolled steel sheet / cold-rolled steel sheet: Steel ingots or slabs are difficult to deform at normal temperature and difficult to process. They need to be heated to 1100 ° C to 1250 ° C for rolling. This HARDOX 400 steel yield strength rolling process is called hot rolling. Rolling at room temperature is generally understood as cold rolling. However, from the point of view of metallurgy, the boundary between hot rolling and cold rolling should be distinguished by the temperature of metal recrystallization, that is, rolling below the recrystallization temperature is cold rolling; Rolling above the recrystallization temperature is hot rolling.
According to the data released by the world iron and Steel Association, the world pig iron production in March 2020 was 103 million tons, a year-on-year decrease of 3.5%, a year-on-year increase of 1.8% in February, and the overseas pig iron HARDOX 400 steel yield strength production excluding China was 36.309 million tons, a year-on-year decrease of 11%.
Temperature has a great influence on the strength of the material, HARDOX 400 steel yield strength. 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.
HARDOX 400 steel yield strength, NM series wear-resistant plates combine high hardness, high strength and high toughness, suitable for those severely worn occasions. The high wear resistance of the wear plate extends the service life of dump truck bodies, excavator buckets, crushers and similar equipment. The hardness of the wear-resistant steel plate is obtained through an effective quenching process. This method can not only achieve higher hardness, but also maintain a lower alloy composition in the steel. The produced wear-resistant plates are easy to machine, twist and weld.
