Even with good heat resistance, but the highest temperature heat-resistant steel castings still subject to certain restrictions, to limit the temperature of many factors, if you want to get a good use of effects, it is necessary to take into account these factors .

On the one hand and the cost of chemical resistant steel castings, primarily manifested in three areas of the heat-resistant steel castings high temperature strength, oxidation resistance and corrosion resistance other effects, corresponding to these properties also have their maximum use temperature a direct impact. On the other hand the impact of casting Size, because when the heat-resistant steel castings in high-temperature environment, and have to withstand deformation due to its own weight, and have to consider the relationship between the size and oxidation rate.
In addition, heat-resistant steel castings working environment is another major factor, the same environmental media, different temperatures, then there will be different results, may cause damage to the surface of the casting.
