Thats the problem with simpletons like you. You get your "facts" from clowns just like you.
"All materials weaken with increasing temperature and steel is no exception. Strength loss for steel is generally accepted to begin at about 300ºC and increases rapidly after 400ºC, by 550ºC steel retains about 60% of its room temperature yield strength."
You are a fucking retard. Sorry, i cant say it in a more polite way.
