    316 fittings corrosion

    How does the 2.5% Mo in 316 Stainless steel metallurgically increases the ability to combat pitting corrosion against chloride ion? Which phase in the 316 is reponsible to combat pitting corrosion?

    Molybdenum disilicide heating elements

    Thanks for the response MTbadger (materials). Response opens up few more and other questions. • The furnace temperature is 1534C for 512 h (elements must be working at 1650C). Cycle duration is 512 h at 1534C. Question: Scenario like this how many hours of life can be expected from the...

    Molybdenum disilicide heating elements

    Thanks to Metalhead97! What if you produce initially too thick a silica layer and expect longer service life? Specially, when I run non-stop continuous cycle for 21 days, I have problems with these elements. The silica layer gets depleted completely from the surface. I had measured ~2 to 3 µm...

    Molybdenum disilicide heating elements

    Hi,Met1CO (Materials: A typical ‘U’ shape MoSi2 heating element with dimensions (Le= 10.5”, Lu = 6.5”, and A= 1”) will weigh 0.72 pounds. Approximate cost of this will be $300 in this country. MoSi2 elements sustain high power densities, 14 W/cm2. But they are brittle at room temperature. Hope...
