Factors to be considered in high and low temperature environment are as follows:
I. Low temperature environmental factors
Cold brittleness of materials, that is, the impact strength of materials decreases at low temperature, generally depends on the chemical composition of materials, and stainless steel chains should not be used below the specified temperature.
Minimum working temperature of stainless steel chain
| Chain material | Minimum operating temperature/℃ |
| Martensite type stainless steel | -70 |
| Austenitic stainless steel | -100 |
II. High temperature environmental factors
The strength of chain decreases with the increase of temperature. The minimum ultimate tensile strength of stainless steel chain in high temperature environment above 400℃ is: the minimum ultimate tensile strength /Kt in general applicable environment temperature (-20℃ ~ 400℃), and the Kt value is shown in the following table:
Temperature coefficient of stainless steel chain
| Ambient temperature | Temperature coefficient Kt |
| Below 400℃ | 1.0 |
| 400℃~500℃ | 1.2 |
| 500℃~600℃ | 1.5 |
| 600℃~700℃ | 1.8 |
| 700℃以上 | Not available |
