Selection of standard material considerations.

1. The requirements for standard parts materials in terms of mechanical properties, especially strength;

2. The requirements of working conditions on the corrosion resistance of the material;

3, The working temperature of the material's heat resistance (high temperature strength, anti-oxidation performance) requirements;

4, The production process aspects of the material processing performance requirements;

5. Other aspects, such as weight, price, and purchase, must be considered.
