Tungsten-Coated Molybdenum for Graphite-Lined Furnaces
Tungsten-Coated Molybdenum for Graphite-Lined Furnaces Progressive Description Example: S24-MO18(W6")-AL-U-PJ-15.75" At temperatures above 2010˚ F (1100˚ C), graphite dust from graphite liners/shields or heating elements can attack and carburize molybdenum sheaths. This causes the sheath to crystallize and become porous, losing its protective properties. The thermal elements in turn crystal..
