Hai Dipil,
WLL work load limit is determined by the manufacturers but SWL is determined by a third party inspection authority.SWL is always lower than the WLL.
I have no idea regarding the effects of temperature on metalic slings.I Have no experience in such cases or never seen high temperature effects on metalic slings or ropes.
