The sale of products implementing national standards t91 alloy tube manufacturers, together for before construction, mining, textile, electric power, boilers, machinery, military, and other leading post-weld heat treatment T91 in t91 alloy tube, cooling temperature is not lower than 100 ℃, If cooled at room temperature, and the environment and more humid how much time t91 alloy tube, prone to stress corrosion cracking. In Germany: Before post weld heat treatment must be cooled to below 150 ℃. In the thicker workpiece, and the presence of fillet has geometry bad circumstances, the cooling temperature is not lower than 100 ℃. If cooling at room temperature, non humid, or prone to stress corrosion cracking
