2, working conditions on the corrosion resistance of materials on the requirements;

3, the working temperature of the material heat resistance (high temperature strength, oxidation resistance) requirements;

4, the production process on the material processing performance requirements;

5, other aspects, such as weight, price, procurement factors should be considered.


Through the five aspects of a comprehensive, comprehensive consideration, the final selection of the relevant national standards for the application of stainless steel.
