Factors to consider when using stainless steel chains in high temperature environments

Factors that need to be considered when stainless steel chains are used at high temperatures exceeding 400°C:

(1) The wear of parts under high temperature is greater than under normal temperature;

(2) Due to the different coefficients of thermal expansion, welding of different materials together may cause thermal fatigue;

(3) When the ambient temperature exceeds 400℃, the thermal ductility of the material and the gap of the chain need to be considered;

(4) Creep;

(5) The influence of temperature fluctuations (chain cooling and expansion will affect the transmission accuracy of the chain);

(6) The chain strength decreases as the temperature rises. In a high temperature environment above 400°C, the minimum ultimate tensile strength of a stainless steel chain is: normal temperature (0-400°C) minimum ultimate tensile strength/Kt, see the following table:
