All materials weaken with increasing temperature and steel is no exception. Strength loss for steel is generally accepted to begin at about 300°C and increases rapidly after 400°C. By 550°C the most common grades (S275 and S355) of hot rolled structural steel retain about 60% of its room temperature yield strength. This is usually considered to be the failure temperature for structural steel. Frequently Asked Questions Reflectix, Inc.Materials that are low (or resistant) to heat flow have higher R-values. Example:If a heat lamp is positioned shining on a 0.5 (width) panel of plywood (R-0.62), within a very short time, the opposite side of the panel will become hot to the touch (the wood has transferred the heat from one side to the other).

Steel material properties - SteelConstructionfoThermomechanically rolled (TMR) steel Quenched and tempered (Q&T) steel. Steel cools as it is rolled, with a typical rolling finish temperature of around 750°C. Steel that is then allowed to cool naturally is termed 'as-rolled' material.
