Material selection
QT450-10 material characteristics
High strength and toughness:
QT450-10 as a ductile iron, its tensile strength and yield strength is similar to that of ordinary steel, and has good plasticity and toughness. This enables it to maintain structural stability and integrity under high pressure and impact loads.
Good wear and corrosion resistance:
QT450-10 material has good wear resistance, which can reduce wear and extend service life during long-term use. At the same time, it also has a certain corrosion resistance, can maintain good performance in a more harsh environment.
Excellent processing performance:
QT450-10 has many advantages in processing, such as fast cutting speed and large cutting depth, which can greatly improve processing efficiency. In addition, the work hardening speed is slow, and it is not easy to crack and break the edge, which is conducive to extending the service life of the tool.
Advantages in Tie plate applications
Strong carrying capacity:
As an important part of the railway track, the Tie plate needs to bear the weight of the train and the dynamic load during operation. The high strength and toughness of the QT450-10 can meet this requirement, ensuring the stability and safety of the track.
Good durability:
Rubber pads need to withstand frequent friction and wear during use. The wear resistance of the QT450-10 can reduce the wear rate of the pad, extend its service life, and reduce the frequency and cost of replacement.
Strong adaptability:
The QT450-10 material can maintain good performance in harsh environments, such as high temperature, humidity or corrosive environments. This enables it to maintain stable performance under various climatic and geological conditions, meeting the needs of Tie plate use.
