I wish to add to the argument.
Temperature and Strength of Metals
Influence of temperature on the strength of metals
Some common types of steel lose 10% of their strength at 450 C (840 F), and 40% at 550 C (1022 F). At temperatures above 800 C ( 1475 F), it has lost 90% of its strength. Other types of steel are made to stand higher tmperatures before losing 10% of their strength, but they are much more expensive (and are weaker at room temperature).
And there are types which actually get stronger, up to 450 F (but then get a lot weaker at higher temperatures
