Strength of heat-resistant steel castings depends on those factors

- Apr 15, 2019-

The properties of heat-resistant steel castings are subject to change, especially after the influence of certain factors.


On the one hand it must be the temperature, the temperature fluctuations have a very large effect on whatever the material is, and that includes heat-resistant steel.Due to many factors such as starting, stopping or overload, the working temperature will fluctuate, and the temperature fluctuation will accelerate the creep process of the material, thus reducing the lasting strength.


There is the effect of stress on one hand, in the face temperature, gap geometry, durable plastic steel, heat treatment process and under the influence of factors such as the composition of the steel, heat-resistant steel castings in stress have different size, and thus affect the brittle material, so this factor must be given enough attention in the design.
