Heat-resistant steel castings quality is largely dependent on the quality of heat-resistant steel, heat-resistant steel because the varieties are more different types of performance and value are also different, so the selection of the time to know how to identify heat-resistant steel quality, so as to ensure the use of heat-resistant steel castings to achieve application requirements.

Identification of some heat-resistant steels really get serious, it must first clear imprint of steel material, under normal circumstances can be identified according to the quality of the product certificate and logo on the package. The distinction between heat-resistant steel on components, there will be some little difficulty, either through color resolution, can also be used to test the relevant judgment.
Among the most obvious way is simple qualitative chemical method, heat-resistant steel products in order to determine the chemical composition, performance characteristics, and so on. In practice, once the temperature after use, you can use this mode to select the appropriate heat-resistant steel products.
