Four-shank elements in 6/12, 9/18, and 12/24 diameters are engineered specifically for furnaces with low chamber heights where elements must be mounted horizontally without sagging.
Moly-D heating elements are manufactured by powder metallurgy. They consist of molybdenum disilicide with additives that prevent recrystallization. Completely stable up to 1800ºC (3270°F), it surpasses other heating element types for high-temperature performance.
Self-Healing Quartz Layer: The oxidation resistance lies in forming an impermeable quartz or glass-like layer. If exposed to contaminants, a lower melting phase forms and drips off, exposing fresh MoSi₂ which generates a new protective oxide barrier.
Electrical Stability: Low specific electrical resistivity with a positive resistance-temperature characteristic. Electrical resistance remains constant over its useful life, permitting mixed use of old and new elements in series.
Nominal Operation: Operates between 1300°C and 1750°C (2372–3182°F). Maximum surface temperature in air is 1800°C (3270°F).
Low Temperature & Harsh Gas Use: May be used below 1300°C (2372°F) in atmospheres harmful to silicon carbide elements (e.g., sulfur dioxide, water-steam). Ductile behavior begins at approximately 1200°C (2190°F).
Select the ideal element grade formulated for your target process temperatures and atmosphere conditions.
