What Temperature Does TZM Oxidize?

The recommended temperatures for using TZM is between 700 and 1,400 degrees Celsius. However, like pure molybdenum, TZM begins to oxidize at 400 degrees Celsius and oxides rapidly in oxidizing atmospheres above 500 Celsius. Similar in strength to pure molybdenum at room temperatures, at operating temperatures exceeding the recrystallization temperature of pure molybdenum (900 to 1,100 degrees Celsius), TZM is much stronger. And in load-bearing applications exceeding 1300 degrees Celsius, TZM is twice as strong as pure molybdenum.
