An industrial heating element is an electro-thermal device converting electrical energy into precise heat through Joule heating. At Leader Steel, we engineer our elements using high-resistance Nichrome alloy (80% Ni, 20% Cr) delivering:
Oxidation resistance up to 1,200°C in air atmospheres
Stable resistivity (±1.5%) across operational temperatures
Mechanical durability with 25% higher yield strength than standard alloys
Rapid thermal response (0.8°C/sec heating rate)
Core Construction: Nichrome wire → MgO insulation → Incoloy 800 sheath → Hermetic seal.
Hermetically sealed units with 99.5% pure magnesia insulation ensuring thermal conductivity > 40 W/m·K
