High Temperature Refractory Corundum Mullite Saggar for Firing Stainless Steel Products

In the demanding field of high-temperature metallurgy and advanced ceramics sintering, the choice of kiln furniture is paramount to product quality, operational efficiency, and cost-effectiveness. Our High Temperature Corrosion-Resistant Corundum Mullite Saggar is engineered specifically for the challenging environment of firing stainless steel and other alloy products, offering unmatched performance and durability.

Superior Material Composition & Properties
Crafted from a meticulously formulated blend of high-purity fused corundum (Al₂O₃) and premium mullite (3Al₂O₃·2SiO₂), this saggar delivers an exceptional combination of properties essential for extreme conditions:

Extreme Temperature Resistance: Stable operation at temperatures up to 1750°C, ensuring integrity during the high-fire cycles required for stainless steel processing.

Outstanding Thermal Shock Resistance: The unique composite microstructure boasts a low thermal expansion coefficient and high thermal conductivity, preventing cracking and spalling during rapid temperature changes.

Superior Chemical Inertness: Exhibits excellent resistance to molten salts, metal oxides, and the corrosive atmospheres (reducing or oxidizing) prevalent during stainless steel firing. This prevents contamination and reaction with the valuable product loads.

High Mechanical Strength: Exceptional load-bearing capacity and creep resistance at peak temperatures prevent deformation and sagging, even under heavy loads over prolonged cycles.

Advanced Design for Optimal Performance
Beyond the material, our saggars feature an optimized design:

Precision Engineering: Uniform wall thickness and tailored geometries ensure consistent heat distribution, minimizing thermal gradients for superior product uniformity.

Enhanced Durability: Reinforced edges and corners combat mechanical wear during handling and stacking, extending service life significantly.

Customization Available: We offer design adaptations to fit specific kiln dimensions and accommodate unique product shapes or firing processes.

Key Application Benefits
When used for firing stainless steel components, powder metallurgy parts, or other high-value metal products, this saggar provides tangible operational advantages:

Prolonged Service Life: Outperforms traditional alumina or clay-based saggars by 3-5 times, drastically reducing downtime and replacement costs.

Product Protection: Its non-reactive surface safeguards stainless steel products from surface defects, discoloration, and chemical contamination, ensuring high yield and superior finish.

Improved Kiln Efficiency: Excellent thermal properties contribute to more efficient heating cycles and potential energy savings.

Reduced Operational Costs: The combination of long lifespan, product protection, and efficiency translates to a significantly lower total cost of ownership.
