At elevated temperatures, conventional steels, unlike ASTM A 335 P91 pipes, begin to lose their microstructural form, leading to failure. A burst or crack in the pipe is a visible fault. But since SA 335 P91 chrome-plated welded pipe is well suited to sustain itself at high temperatures, failure rates are extremely low.
