Why is the service temperature of heat-resistant steel castings limited?
Heat-resistant steel casting manufacturers: Even though it has good high temperature resistance, the use temperature of heat-resistant steel castings is still subject to certain restrictions, and there are many factors that limit this temperature. If you want to obtain good application effects, These factors must be taken into consideration.
On the one hand, it is related to the chemical cost of heat-resistant steel castings, which is mainly reflected in the impact on the high-temperature strength, anti-oxidation performance and anti-corrosion performance of heat-resistant steel castings. Correspondingly, these properties also have an impact on its use temperature. direct impact.
On the other hand, there is the influence of casting specifications and dimensions, because when heat-resistant steel castings work in high-temperature environments, they have to withstand deformation caused by their own weight. At the same time, the relationship between size and oxidation rate must also be considered.
In addition, the working environment of heat-resistant steel castings is also another major factor. In the same environmental medium, different temperatures will have different results, which may cause damage to the surface of the castings.
