Another paper for those who are interested.

Journal of Constructional Steel Research
Volume 66, Issue 5, May 2010, Pages 634-647

Ultimate strength reduction factors for different stainless steel grades from EN 1993-1-2 and Euro Inox/SCI design manual for structural stainless steel.

Thus, from the freezing point of water to about 120 F the tested steels loose about 0.2% of their strength.

Also, the issue of absorbing radiant energy from the Sun was brought up. Yes, steel absorbs both visible and infrared light.

Absorption wavelength spectrum for different materials: glass, metal and others.

Thus, because steel absorbs both visible and infrared radiation from the sun it will be warmer than surrounding air temperature. https://endurancelasers.com/ab...different-materials/
