What is temperature of stainless steel chain used for?

Low temperature will cause material brittleness. Lowest temperature of Martensitic stainless stell is -70℃。 Lowest temperature of Austenitic stainless steel is -100℃. 

Normal stainless steel chain using in the field with temperature above 400℃ will cause material heat fatigue, expansion, deformation, pitch accuracy loss and breaking load decrease significantly.
